I just fished watching the whole playlist of gemology for newbs. Such great, useful information. Thank you! I've been studying geology and minerology as a hobby, and this is just one more amazing aspect of what the earth can create. Maybe next time I'm in Bangkok I will stop by your shop to thank you in person and nerd out about rocks together. Excited to watch the other offerings on the channel.
Thank you kindly for these videos. I’ve thoroughly enjoyed going through them the last couple of weeks. I got into buying stones via eBay during lockdown (where all the true gem experts look for stones, I’m sure), so I am finding your advice to be very interesting. I have about 3 shoeboxes full of (almost entirely synthetic) rubies, sapphires, spinel, tourmaline and quartz, and it would be nice if I could figure out exactly what’s what. Who knows. Some of them might even be worth more than I paid for them (narrator: deep down he knew they probably weren’t worth anything at all, but he chose to indulge in what little hope he could muster). So thanks for these vids, and please keep em comin’. Be well.
My pleasure to serve, Daniel. I'm glad you're enjoying what i've got to offer. I've got some more videos planned that might help you with exactly the sort of thing you're talking about. Hopefully sooner than later XD.
Peter, thank you! I love it! Going to re-watch and start prioritizing which pieces I need first. So glad to see you're doing well and making videos again (this is my new favorite)!
Can you add a list of these items, with links to the specific ones you prefer, in the description in the future? Or edit this video to add them? That would be super helpful!!
Hi Peter first off thank you for this video which is exactly the information and guidance that I need. It is 07 October 2024 and the relevance of what you shared in this video has not faded or changed. I have been delaying in trading not being to answer questions in my mind about trainings and what I need to prioritize. Now I have a very good idea! Thank you.
You are so sweet, Peter! Love this video and this was fun to watch and absolutely gold-worthy for the information you packed in. I am just getting into gemstones and love learning all these things. Thank you for sharing your expertise!
You are a gem yourself my friend :-) stay blessed. Now because of you i have enrolled into a diploma of gemology. Let's see where life takes me. All the best
Your video reminds me of my undergrad and grad courses in optical mineralogy and petrology (way back in the last century). I retired a couple of years ago after a long career as a consulting geologist/geochemist. Now that I have a lot of time on my hands, I'll dive into gem and mineral collecting. I wasn't much into gemstones, as a lot of my work involved radioactive minerals and nonmetallic industrial minerals, but I look forward to re-learning things I haven't thought much about i a very long time. It ought to keep me out of the local bars and also out of my wife's hair.
The spectroscope is a tough one, and caused me a lot of anguish at the beginning too. I suggest starting with known red garnets - most of these are pyrope/almandine garnets and their spectrum is really obvious. Spessartite (mandarine garnet) is also good. If you have any access to synthetic ruby, this is also a great one to get comfortable with the spectroscope. Best of luck Cheryl~!
I'd love to if I can get my hands on one. They're not so common in our area, as most people have offices and opt for the fully electrical desk models. I know that the Gem-A people (British Program) often have them in their kits, and im super jealous. My ghetto fix is a pair of polarizing sunglasses, but thats far from a lab-worthy tool XD
Microscope yes I heared some high quality juwellers like Fabergé did and some others use it also with manifacturing jewellery into the detail, not only with a loupe.
I use a microscope myself when engraving - but I started with a loupe for the first half-year, and I know of some excellent engravers that continue to use a loupe. Personally i like having both hands free. As they say, the poor craftsman blames his tools.
Hi Peter the question I have is when I go in the field always I deal with rough gemeston what is the best tools to go in to the field thank you so much
@@abdullahihussein3034 That will depend entirely on the types of stones you're going to encounter. If you're looking for specific stones like ruby, then you'll need to know what tools will differentiate ruby from its simulants or synthetics. If you're looking for "everything" then you'll need a full gem lab. So you'll need to be aware of what you're going to buy first, and take the tools that will support that goal. Of course, a good loupe and strong flashlight is a great start.
Why specifically *iron* tweezers, rather than (for example) stainless steel? Also, what is the Chelsea (sp?) scope actually used for, and do you have a link or recommended type?
Hi Brian - Stainless would also be fine, though i don't know that I've seen many. Most of the quality ones that i've seen have been some variety of iron or steel (no idea on alloy or carbon content as that is outside my need to know on this topic) or otherwise Titanium. Stainless steel would also be soft enough for appropriate use, if you happen to find a pair. Chelsea filter was originally designed in Chelsea, UK for use with sorting emeralds as it helps uncover fluorescence. I've got another video on that topic if you're curious: ua-cam.com/video/4o-9t5C6FHY/v-deo.html
Hey Peter, I’m glad your out of lockdown and looking well; it’s no fun is it, I guess we have all been through a few by now. A very informative video about the equipment needed to verify gemstones. My thoughts are build up your equipment base carefully over time. It’s also good to get a second opinion from a lab if your lucky enough to have one near, even better if you can get stones tested for mates rates. Anyway, I’m glad your back at your office. Keep safe my friend. Rog. 😀✨
Thanks Rog, and I totally agree with you on all accounts. Best to have the right tools, and thats SO hard to do if you've not had the chance to get familiar with the "right" tools before buying from zero experience XD I've done this many times myself. Absolutely on lab second opinions ~ I use them frequently myself. I'm fortunate to be in Bangkok where we've got so many knowledgeable and experienced cohorts about us eh? Cheers sir~
The most important thing in choosing a light source is knowing what wave-lengths are available from the light source. Ideally we want full spectrum light source. The way to double check the source before checking the spectrum on the stone is to look at the light using the spectroscope first, without a stone to see what absorption pattern is there already. LED and fluorescent etc tend to eat more wavelengths/ not emit them in the first place.
@@GemologyforSchmucks Thank you for the information. I found an inexpensive halogen source, I'll start with that. I searched for images of emission data of various light sources, and other than the sun, they all seem to have areas of weakness & strengths. Does that imbalance make spotting the absorption lines that happen to be in those areas, more difficult (with either a spectroscope or spectrometer)?
@@timmsmiithgm557 halogen should be about as good as you get. Those bulbs tend to burn out more quickly, but theyre also a strong and quality spectrum. It should help you get comfortable with reading spectra faster. I suggest starting with pyrope-almandine-spessartite garnets, zircons, and synthetic sapphire and ruby. These are spectra that are typically easier to recognize and will build your confidence.
Hi Peter, I'd love to hear more about the spectroscope. On eBay, I can see diffraction grating types starting at about $32, and prism types starting at $62, while a Gem-A diffraction grating spectroscope is about $126. Is there a big difference between the unbranded cheapies vs. name-brand types? (I followed your advice when I bought my Belomo loupe, and you were right on the money, the Belomo is WAY superior to a cheaper loupe) While you're at it, other resources on using the spectroscope (books you like, for example) would be great. Thanks!
The spectroscope is one where I wouldn't go the ultra cheap route. Its got a learning curve to get competent at using it, and you don't want to be second guessing your equipment and wondering if you can't see the spectra because the tool is janky. Somewhere around $100 is the price i've paid, and I've not been around anyone advocating the cheaper models. I use the smaller OPL spectroscope. There are a few books on spectroscopy, "The Spectroscope and Gemmology" by Basil Anderson et all (link below) seems to be the more widely recommended. Otherwise i'd suggest getting around some red/orange garnets, zircons, rubies, blue sapphires, and red spinels (synthetic ok for this purpose) and get reaaaaally comfortable looking for spectra on those items first before you go out "into the wild". www.amazon.com/Spectroscope-Gemmology-Basil-Anderson/dp/0943763525/ref=sr_1_3?keywords=spectroscope&qid=1636965578&s=books&sr=1-3
A great book for overall gem identification is Richard T. Liddicoat's "The Handbook of Gem Identification" Otherwise there is a phenomenal (and expensive) series called "The Photoatlas of Inclusions Gemstones" by Gubelin and Koivula. This is in like 4-5 volumes now I think. It all depends on what sort of info you're looking for. If you want to get really deep into one type of stone, there are certain books that are specialized. General identification, i'd suggest Liddicoat's handbook.
Hi Jermane, That pouch was provided to us by AIGS when I first started my AG program with them a number of years ago. They were specially made and marked for AIGS. I imagine once someone found the tools that they wanted to take into the market most regularly, a decent leatherworker could make a suitable (or even more deluxe) alternative.
Hey Peter this was very helpful I have many of the items that you have I just don’t know if I can trust my refractometer it is one that you do not have to use oil for.
Hi Christoph~ The RI liquid (especially 1.80/1.81 RI liquid) is essential for optical contact between the stone and the device. If yours doesn't use a liquid i'd be VERY suspicious. Cheers
Can gems that are set in jewelry be tested on a refractometer? I want to be confident in the stones and jewelry that I sell so I would like to learn how to test them.
As long as the stone has a facet that can sit flat on the hemicylinder, yes. For example if the prongs are too high, and stick up above the table of the stone, then it would be a problem.
Now as I got my mother hooked on gems while visiting Vietnam, your series and channel got really really useful. My mother is a new fan beside me 😉💎🔺♦️🔻💎
Absolutely possible. The lighting base is more important for gemology, but generally there is a strong overlap in the quality of optics. The one advantage of some microscopes for stone setting is the optical engineering that builds in a larger depth of field. It's easier to use for longer periods of time without feeling woozy or unduly strained.
Hi Richard, it would be best to seek out a gemologist near you to assist you in identifying your stones. The price of exporting, importing and testing gems will likely be more expensive than buying the instruments and doing it yourself.
Alright, so are the ~150$ refractometers on ebay, that come with the fluid, worth the investment? Slightly useful? Im in estate sale/pawn shop centeral here in the midwest. Lots of opportunities to get cheap jewelery with stones.
Having not used those models myself its hard for me to have a supportive opinion. The "Fable" brand refractometers are quite budget friendly and I have used those (and know several other professionals that use them regularly). I can recommend that brand without issue.
If you can source and "pop outs" or cheaper diamonds I might buy them. Might not be worth your time but if you come across some let me know. Also general stones you want to get rid of at a low price. Im not that picky just looking for a bargain.
Hi Heman ~ I bought this from a local supplier in Bangkok. If you search online id use the term "3 in 1 LED flashlight" and maybe add "gemological flashlight" if you don't find results you like. Cheers
Someonelse might have asked but i didnt read comments , the little carry around case you show does anyone sell a package deal where you get everything in the case you highlighted?
This one was provided by my school AIGS when I started the A.G. program with them. I'm sure there are some independent folk selling kits as well, but I haven't got one to recommend at the moment.
The experienced gemologists (including lab gemologists) I know all use this type of refractometer. There are certain Raman devices that are supposedly highly effective, but not even close to the same price range as the standard gemological refractometer. I havent used the other type of device, and I enjoy the surety that comes with using mechanical devices. They don't lie as long as you know how to properly use them.
Hi Danny - in order for the refractometer to work at all, you need a polished surface. The better the polish, the better your reading will be. Cabochons (also polished, though not faceted) can be read using the standard refractometer with the spot reading technique (not beginner friendly). Some rough with natural crystal faces may be readable, though its typically not as easy due to the irregularity of the surface. Hope that helps clarify the question.
@@dannyd8799 That depends totally on what type of rough you're looking at. If it is a total mystery, you'll need to get a facet put on the stone and have a gemologist do an actual identification. If you can narrow the possibilities down, then you may be able to rule out the others depending on their characteristics. My videos on the spectroscope and polariscope should help you. ua-cam.com/video/seITqf1EWvo/v-deo.htmlsi=D7YoG9zqH_-QClbm ua-cam.com/video/ul3dGfsNW_A/v-deo.htmlsi=Ixc9a4wkIfrXueSQ
As a guitarist, and musician of other kinds, it's generally known as GAS (gear acquisition syndrome). You see the pretty candy, and you want it all for yourself!
So I’m guessing your stones are selling at a lower price? By the way, Peter, I’d like to know if I can mention your name to get a discount on your gem microscope?
Hi Dan ~ Gemstones are an interesting market - there will be some stones (common/ commercial quality) that might experience a flash sale or a discount to get them to move, but investment level stones don't tend to get discounted. Folk would rather pass them to their heirs and let them sell them in another generation. I wish my name would inspire microscope discounts, but I think i'm still small fish to those companies :D
Hello, I enjoy watching and learning from your videos. I have a question... is there a tool that can give you the refractions of stones for identification that are in a setting, like in a ring or necklace. Or do they all have to be loose stones to test?
as long as a facet sticks up above the setting of the jewelry enough to sit on the hemisphere of the refractometer, it will work on set jewelry aswell.
@@GemologyforSchmucks Thank you so much for answering. Now I’m excited to break out all my jewelry and start learning. Thanks again for sharing your knowledge with us, I enjoy the content.
G'day Pete, absolutely love your videos and attitude towards teaching. I have a question if you don't mind! I've been dabbling in gemmology (thinking of doing a diploma next year for fun), but I've been absolutely struggling with the Spectroscope. Can I ask, is it normal to struggle to see through it properly? I've gotten a bit better with it in time (maximising path of light for the scope) but I can't help but feel like I'm peeping through an ant-sized key hole, looking into a movie theatre, that's out of focus, blurry vision, foggy, and like I have a drag-queen's eyelashes at the same time. Is this normal and just expected to push through with?
Howdy, Easton Thanks for your kind words~ as to your question, the spectroscope is a supreme challenge. I love it, but it's not easy to use, and not easy to learn. What I'd suggest doing is getting ahold of some red garnets (pyrope and or almandine, it doesnt matter), and spessartite garnet , zircon (the natural mineral in any colour) and synthetic corundum and or synthetic spinel. These stones all have strong and more obvious spectra. When you have a stone that you KNOW will have a diagnostic spectrum, and you get comfortable finding spectra in other stones more reliably. Cheers and best of luck to you. If you have issues sourcing the stones, send me an email at thegemshepherd@gmail.com
Hi Peter, many thanks for so many awesome videos, I've learnt so much already. I had a question for a new schmuck like me I was wondering A lot of these instruments require practice and experience looking at different stones to know what to look for. Are there any simple field devices used to test sp grav? 25ml measuring cylinder on scales etc (I know I sound thick lol). Reason I ask is it gives an easy measurable number, so check charts rather than needing experience, so would be really helpful with identification for a beginner. Many thanks in advance
I'd say that the value of the tool and the shortness of the learning curve on the dichroscope and loupe are MUUUUCH more impressive than trying to mess about with S.G. Specific gravity is one of the most deceitful pieces of information that many early gemologists cling to. It's like a splintered 2x4 in the midst of the freezing sea. Learn to identify pleochroism with a dichroscope ( have a video on that) and doubling with a loupe (I have a video on that) and you will be miles ahead of what S.G. can tell you most of the time. The big thing in identifying stones is really becoming acquainted with what to look for. If you're wanting to by-pass that, its more danger than it is benefit.
@@GemologyforSchmucks Thank you so much for replying! And for so much useful information, I really appreciate it. The analogy for Sp was hilarious, I will take your advice there. It definitely isn't laziness (optical physics is my weakest science) so I had a natural pull towards the maths. But I will put the time in learning the dichroscope, your advice makes total sense, I can imagine I'm not the first newb to ask you the same thing (apologies) Sorry to ask one more (probably silly) question. If wanting to be safe as a beginner, and buying certified, when looking to buy abroad (eg Pakistan) are all certs legit? I'm spending some time in Peshawar and northern Pk, I want to use the time to learn as much as I can etc, but I don't really know where to start or who to trust (besides my friends there). Would you suggest me taking the time to do a gemology course there if i can? Apologies again for all the waffle, and thank you again for kindly giving me your time, it means a lot
@@tobiasmccallum9697 Don't worry about silly questions. You're on the quest for truth, and I enjoy that very much. To answer your question on gem reports (known to some as certificates... which is a sensitive and inaccurate word in the gem trade, though it is often used) NO. Not all are legit. Some labs peddle lies with paper, and thats how they make money from folk trying to sell mystery gravel. Do I suggest doing a gemology course, sure - as knowledge is power. If you're in that part of the world I think my best advice is two-fold. 1) if you want to buy "intentionally" then pick one type of stone that you're interested in and learn as much as you can about ONE type. They have so many stones flowing out of there in sooooooo many different qualities. 2) Don't buy until you're ready to loose your money. If you're too caught up in having a guarantee, then doom is around the corner. When you let go, then you can start to get analytical and see hidden truths. Its weird, but that's been my experience. Start slow and see what can be seen (and learn how to test and qualify it) and scale from there. Best of luck Tobias~
@@GemologyforSchmucks Thank you so so much Peter, that all makes total sense. I really appreciate all of the help, I will do all those things tbh! Sending all of my best .......I cant help myself asking one more question (promise its the last lol). Of emerald, ruby/sapphire, aquamarine, which one would you say was for a beginner the least difficult to tell apart from simulants, and are lab grown from all of them just as hard to spot without lab kit / years of experience, or do they differ in difficulty?
@@tobiasmccallum9697 I'd say aquamarine is the easiest out of these, and the treatment situation is the simplest, and much less frequent simulants/synthetics.
This partcular set isn't sold as a kit, and unfortunately the manufacturer of this refractometer is no longer making them. Sachitools.com is a good place to start your research on instruments though~
Estimating the value of jewelry has two main roads, so it really depends on who you speak to. Some people do appraisals for insurance purposes (they estimate the replacement value) and their fees will depend entirely on what they want to charge and you'll need to research who is in your area. The saleable value of your piece/ gemstone is much more difficult to estimate, and I wouldn't trust anyone except those that frequently deal in those gemstones. Jade and turquoise can be especially difficult because so few people deal in them. They can have incredibly high values or incredibly low values, and the average price isn't really common knowledge. For example, someone who usually deals in diamonds may be clueless about average prices of popular ruby sizes, qualities and colours. Long-story short. Its important to find an expert on the type of stone you're interested in getting an estimate for, and then shop their prices and those at a similar skill/experience level.
This is why I only order from India. I can get emeralds and color diamonds and tanzanite and sapphires and opals etc and I can buy in bulk all for $12.00 hahaha! Oh okay.. my humor. You have added one more subscriber.
Hi guys, can anyone recommend me a good digital gem microscope? I want to take shots of the gems and upload them to my PC. Thank you and have a nice day everyone!
Many of the popular brands of gem microscopes (leica, olympus, motic, etc) have some models with built in cameras, or my preference is a trinocular model that you can attach a separate camera to. Do be aware that many trinocular models will require some sort of adapter if you are using a DSLR camera.
Glad to hear that there is something more affordable that is serving you. I'd be suspicious unless i'd tested a known stone with it, but otherwise, i'm glad to hear it.
While I love your content and would share you to the whole world, I'd rather gatekeep you and use you as a top grade resource for us hobbyists and traders; Liking and subbing is all I'm able to do without giving up the gift of having found you lmao
Everything has a value/ worth. The bigger question is how the object is positioned and which potential buyers it is put in front of. Some people will spend tens or hundreds of thousands on a time piece, but someone such as myself wouldn't give the object more than a parting glance.
For red gemstones, in jewlery, I have noticed, that under long uv light, they flourence RED, or ORANGe, or nothing For a novice like me, this in confusing. Can you clarify please.
Colour and UV reaction are both deceptive. I don't recommend anyone relying on them. Many early gemology students WANT to trust them, but in my opinion, they're more likely to lead you astray than help.
If you start learning gemology, you don't need to buy high-end tools, you can get all these items from China with half of the price or less, the brand is FABLE from Shenzhen,
I think traditional wisdom is - if a large enough purchase is made, you can often get a free hat. Of course the other traditional wisdom is: there is no such thing as a free lunch.

Absolutely on lab second opinions ~ I use them frequently myself. I'm fortunate to be in Bangkok where we've got so many knowledgeable and experienced cohorts about us eh?
Cheers sir~
Another informative video - thanks! What is the best type of light source when using a spectroscope (halogen, tungsten, led, ...)?
The most important thing in choosing a light source is knowing what wave-lengths are available from the light source. Ideally we want full spectrum light source. The way to double check the source before checking the spectrum on the stone is to look at the light using the spectroscope first, without a stone to see what absorption pattern is there already. LED and fluorescent etc tend to eat more wavelengths/ not emit them in the first place.
@@GemologyforSchmucks Thank you for the information. I found an inexpensive halogen source, I'll start with that. I searched for images of emission data of various light sources, and other than the sun, they all seem to have areas of weakness & strengths. Does that imbalance make spotting the absorption lines that happen to be in those areas, more difficult (with either a spectroscope or spectrometer)?
@@timmsmiithgm557 halogen should be about as good as you get. Those bulbs tend to burn out more quickly, but theyre also a strong and quality spectrum. It should help you get comfortable with reading spectra faster. I suggest starting with pyrope-almandine-spessartite garnets, zircons, and synthetic sapphire and ruby. These are spectra that are typically easier to recognize and will build your confidence.
@@GemologyforSchmucks Thank you, I really appreciate your help & am a big fan of your videos! ;-)
Yay a new video !!
Huzzah~!
Hi Peter, I'd love to hear more about the spectroscope. On eBay, I can see diffraction grating types starting at about $32, and prism types starting at $62, while a Gem-A diffraction grating spectroscope is about $126. Is there a big difference between the unbranded cheapies vs. name-brand types? (I followed your advice when I bought my Belomo loupe, and you were right on the money, the Belomo is WAY superior to a cheaper loupe) While you're at it, other resources on using the spectroscope (books you like, for example) would be great. Thanks!
The spectroscope is one where I wouldn't go the ultra cheap route. Its got a learning curve to get competent at using it, and you don't want to be second guessing your equipment and wondering if you can't see the spectra because the tool is janky. Somewhere around $100 is the price i've paid, and I've not been around anyone advocating the cheaper models. I use the smaller OPL spectroscope. There are a few books on spectroscopy, "The Spectroscope and Gemmology" by Basil Anderson et all (link below) seems to be the more widely recommended. Otherwise i'd suggest getting around some red/orange garnets, zircons, rubies, blue sapphires, and red spinels (synthetic ok for this purpose) and get reaaaaally comfortable looking for spectra on those items first before you go out "into the wild".

Oooo~! Universe cross-over XD
Thanks so much, this was very helpful. Do you recommend any book to use along with these tools to help ID gemstones?
A great book for overall gem identification is Richard T. Liddicoat's "The Handbook of Gem Identification" Otherwise there is a phenomenal (and expensive) series called "The Photoatlas of Inclusions Gemstones" by Gubelin and Koivula. This is in like 4-5 volumes now I think.
It all depends on what sort of info you're looking for. If you want to get really deep into one type of stone, there are certain books that are specialized.
General identification, i'd suggest Liddicoat's handbook.
Can I get some information on that pouch that you carry all of your tools? Thank you
Hi Jermane,
That pouch was provided to us by AIGS when I first started my AG program with them a number of years ago. They were specially made and marked for AIGS. I imagine once someone found the tools that they wanted to take into the market most regularly, a decent leatherworker could make a suitable (or even more deluxe) alternative.
Awesome Stuff. Thanks for sharing.
Thanks, and glad to be of service.
Hey Peter this was very helpful I have many of the items that you have I just don’t know if I can trust my refractometer it is one that you do not have to use oil for.
Hi Christoph~ The RI liquid (especially 1.80/1.81 RI liquid) is essential for optical contact between the stone and the device. If yours doesn't use a liquid i'd be VERY suspicious.
Cheers
Good information.
Thank you~
Can gems that are set in jewelry be tested on a refractometer? I want to be confident in the stones and jewelry that I sell so I would like to learn how to test them.
As long as the stone has a facet that can sit flat on the hemicylinder, yes. For example if the prongs are too high, and stick up above the table of the stone, then it would be a problem.
Great videos! Easy to follow and enjoyable! Xxx
Thanks Kay ~ glad to be of service.

I'm so glad to be of service to such illustrious persons~!
Would I be able to purchase one microscope head, and use it for both gemology, and stone setting, with different bases?
Absolutely possible. The lighting base is more important for gemology, but generally there is a strong overlap in the quality of optics. The one advantage of some microscopes for stone setting is the optical engineering that builds in a larger depth of field. It's easier to use for longer periods of time without feeling woozy or unduly strained.
@@GemologyforSchmucks Alright, awesome. I appreciate all the responses, and content. You really can't watch them just once.
Thank you so much for the great information sir,

What is a good tool to examine alexandrite. Thank you.
A refractometer, a two way torch and a good loupe are indispensable for alexandrite ~ thanks for reaching out.
I have seen stone of types , how can I sample them to you,as I couldn't afford buying the instrument, ? Richard Bassey from Nigeria. Nigeria
Hi Richard, it would be best to seek out a gemologist near you to assist you in identifying your stones. The price of exporting, importing and testing gems will likely be more expensive than buying the instruments and doing it yourself.
Alright, so are the ~150$ refractometers on ebay, that come with the fluid, worth the investment? Slightly useful? Im in estate sale/pawn shop centeral here in the midwest. Lots of opportunities to get cheap jewelery with stones.
Having not used those models myself its hard for me to have a supportive opinion. The "Fable" brand refractometers are quite budget friendly and I have used those (and know several other professionals that use them regularly). I can recommend that brand without issue.
@@GemologyforSchmucks alright, thank you.
If you can source and "pop outs" or cheaper diamonds I might buy them. Might not be worth your time but if you come across some let me know. Also general stones you want to get rid of at a low price. Im not that picky just looking for a bargain.

What can I buy to determine e the gem like components to Eudialyte?
I beg your pardon, but i'm not certain what the question is. Perhaps you can rephrase it for me.
Someonelse might have asked but i didnt read comments , the little carry around case you show does anyone sell a package deal where you get everything in the case you highlighted?
This one was provided by my school AIGS when I started the A.G. program with them. I'm sure there are some independent folk selling kits as well, but I haven't got one to recommend at the moment.
Hi is there an electronic refractometer? or one without any liquid?
Cheers
The experienced gemologists (including lab gemologists) I know all use this type of refractometer. There are certain Raman devices that are supposedly highly effective, but not even close to the same price range as the standard gemological refractometer. I havent used the other type of device, and I enjoy the surety that comes with using mechanical devices. They don't lie as long as you know how to properly use them.
What refractor meter do you recommend for large unfacted rough.
Hi Danny - in order for the refractometer to work at all, you need a polished surface. The better the polish, the better your reading will be. Cabochons (also polished, though not faceted) can be read using the standard refractometer with the spot reading technique (not beginner friendly). Some rough with natural crystal faces may be readable, though its typically not as easy due to the irregularity of the surface. Hope that helps clarify the question.
@@GemologyforSchmuckssorry one more question. How would I then check the legitimacy of gemstone rough? Is there a better way?
@@dannyd8799 That depends totally on what type of rough you're looking at. If it is a total mystery, you'll need to get a facet put on the stone and have a gemologist do an actual identification. If you can narrow the possibilities down, then you may be able to rule out the others depending on their characteristics. My videos on the spectroscope and polariscope should help you.

So I’m guessing your stones are selling at a lower price?
By the way, Peter, I’d like to know if I can mention your name to get a discount on your gem microscope?
Hi Dan ~
Gemstones are an interesting market - there will be some stones (common/ commercial quality) that might experience a flash sale or a discount to get them to move, but investment level stones don't tend to get discounted. Folk would rather pass them to their heirs and let them sell them in another generation.
I wish my name would inspire microscope discounts, but I think i'm still small fish to those companies :D
@@GemologyforSchmucks peter, you may want to look into affiliate sales/marketing. Of course only for products you believe in.
Hello, I enjoy watching and learning from your videos. I have a question... is there a tool that can give you the refractions of stones for identification that are in a setting, like in a ring or necklace. Or do they all have to be loose stones to test?
as long as a facet sticks up above the setting of the jewelry enough to sit on the hemisphere of the refractometer, it will work on set jewelry aswell.
@@GemologyforSchmucks Thank you so much for answering. Now I’m excited to break out all my jewelry and start learning. Thanks again for sharing your knowledge with us, I enjoy the content.
G'day Pete, absolutely love your videos and attitude towards teaching. I have a question if you don't mind! I've been dabbling in gemmology (thinking of doing a diploma next year for fun), but I've been absolutely struggling with the Spectroscope. Can I ask, is it normal to struggle to see through it properly? I've gotten a bit better with it in time (maximising path of light for the scope) but I can't help but feel like I'm peeping through an ant-sized key hole, looking into a movie theatre, that's out of focus, blurry vision, foggy, and like I have a drag-queen's eyelashes at the same time. Is this normal and just expected to push through with?
Howdy, Easton
Thanks for your kind words~ as to your question, the spectroscope is a supreme challenge. I love it, but it's not easy to use, and not easy to learn. What I'd suggest doing is getting ahold of some red garnets (pyrope and or almandine, it doesnt matter), and spessartite garnet , zircon (the natural mineral in any colour) and synthetic corundum and or synthetic spinel. These stones all have strong and more obvious spectra. When you have a stone that you KNOW will have a diagnostic spectrum, and you get comfortable finding spectra in other stones more reliably.
Cheers and best of luck to you.
If you have issues sourcing the stones, send me an email at thegemshepherd@gmail.com
@@GemologyforSchmucks Great advice thank you!
Hi Peter, many thanks for so many awesome videos, I've learnt so much already. I had a question for a new schmuck like me I was wondering
A lot of these instruments require practice and experience looking at different stones to know what to look for. Are there any simple field devices used to test sp grav? 25ml measuring cylinder on scales etc (I know I sound thick lol). Reason I ask is it gives an easy measurable number, so check charts rather than needing experience, so would be really helpful with identification for a beginner. Many thanks in advance
I'd say that the value of the tool and the shortness of the learning curve on the dichroscope and loupe are MUUUUCH more impressive than trying to mess about with S.G. Specific gravity is one of the most deceitful pieces of information that many early gemologists cling to. It's like a splintered 2x4 in the midst of the freezing sea. Learn to identify pleochroism with a dichroscope ( have a video on that) and doubling with a loupe (I have a video on that) and you will be miles ahead of what S.G. can tell you most of the time. The big thing in identifying stones is really becoming acquainted with what to look for. If you're wanting to by-pass that, its more danger than it is benefit.
@@GemologyforSchmucks Thank you so much for replying! And for so much useful information, I really appreciate it. The analogy for Sp was hilarious, I will take your advice there. It definitely isn't laziness (optical physics is my weakest science) so I had a natural pull towards the maths. But I will put the time in learning the dichroscope, your advice makes total sense, I can imagine I'm not the first newb to ask you the same thing (apologies)
Sorry to ask one more (probably silly) question. If wanting to be safe as a beginner, and buying certified, when looking to buy abroad (eg Pakistan) are all certs legit? I'm spending some time in Peshawar and northern Pk, I want to use the time to learn as much as I can etc, but I don't really know where to start or who to trust (besides my friends there). Would you suggest me taking the time to do a gemology course there if i can? Apologies again for all the waffle, and thank you again for kindly giving me your time, it means a lot
@@tobiasmccallum9697 Don't worry about silly questions. You're on the quest for truth, and I enjoy that very much.
To answer your question on gem reports (known to some as certificates... which is a sensitive and inaccurate word in the gem trade, though it is often used) NO. Not all are legit. Some labs peddle lies with paper, and thats how they make money from folk trying to sell mystery gravel.
Do I suggest doing a gemology course, sure - as knowledge is power.
If you're in that part of the world I think my best advice is two-fold. 1) if you want to buy "intentionally" then pick one type of stone that you're interested in and learn as much as you can about ONE type. They have so many stones flowing out of there in sooooooo many different qualities. 2) Don't buy until you're ready to loose your money. If you're too caught up in having a guarantee, then doom is around the corner. When you let go, then you can start to get analytical and see hidden truths. Its weird, but that's been my experience. Start slow and see what can be seen (and learn how to test and qualify it) and scale from there.
Best of luck Tobias~
@@GemologyforSchmucks Thank you so so much Peter, that all makes total sense. I really appreciate all of the help, I will do all those things tbh! Sending all of my best
.......I cant help myself asking one more question (promise its the last lol). Of emerald, ruby/sapphire, aquamarine, which one would you say was for a beginner the least difficult to tell apart from simulants, and are lab grown from all of them just as hard to spot without lab kit / years of experience, or do they differ in difficulty?
@@tobiasmccallum9697 I'd say aquamarine is the easiest out of these, and the treatment situation is the simplest, and much less frequent simulants/synthetics.

What is the cost for estimating a jewelry like turquoise or crystal jade ?
Estimating the value of jewelry has two main roads, so it really depends on who you speak to. Some people do appraisals for insurance purposes (they estimate the replacement value) and their fees will depend entirely on what they want to charge and you'll need to research who is in your area. The saleable value of your piece/ gemstone is much more difficult to estimate, and I wouldn't trust anyone except those that frequently deal in those gemstones. Jade and turquoise can be especially difficult because so few people deal in them. They can have incredibly high values or incredibly low values, and the average price isn't really common knowledge. For example, someone who usually deals in diamonds may be clueless about average prices of popular ruby sizes, qualities and colours. Long-story short. Its important to find an expert on the type of stone you're interested in getting an estimate for, and then shop their prices and those at a similar skill/experience level.

Many of the popular brands of gem microscopes (leica, olympus, motic, etc) have some models with built in cameras, or my preference is a trinocular model that you can attach a separate camera to. Do be aware that many trinocular models will require some sort of adapter if you are using a DSLR camera.
They have decent refractometers on eBay for $70 . They work great
