I bought a large opal doublet because I love the shimmer in it and I can carry it anywhere as the glass its sandwiched by is protecting it. Allows you to see the beauty for a affordable price
Hi, thank you for the video . Can you show how to identity the gems when they already set in the jewelry, because the stone’s visibility is much less. Thanks
A jewelers loupe can come in handy to identify internal flaws that are characteristic of natural stones like diamond, ruby, sapphire, emerald, tourmaline. Sometimes you can tell by the color, or the way the light refracts through the stone or by the edges. Oftentimes faceted stones with soft or rounded edges are cz or glass. And if there's a bubble it's definitely fake (glass)!
Carefully examine the color across the stone. If it is the same, all the way across, it is most likely dyed Howlite or plastic. If the color varies, it is turquoise.
Try the match test. Touch it with the hot match and see if it melts. That's what I was advised when moving to New Mexico in the seventies. We used to get good size rings for five dollars straight from the natives. All mine was stolen in a home robbery. No increase in value for me.
I have a teardrop shaped diamond (?) earring that's incredibly beautiful, but I don't know if it's an actual diamond, and most jewelers I went to told me they charge to check that kind of stuff, so being able to tell a bit myself would be an incredible skill!
Take it to the pawnshop dumb dumb!!!! And make them test it in front of you!!! If it beeps and gose all the way up ! It's most likely real. And do be careful and watch a few diamond tester videos but taking it to the pawnshop can tell you very quickly whether or not it's real or fake act like you want to pawn it !!!!!😮💨🙄
I have a large red stone that was taken from an antique necklace. A jeweler who was a gemologist said it was a red spinel but would not write a report. I was there by appointment for a paid appraisal. He acted like he really didn't know what it was. But it's eye clear and flawless. Looks like a burmese Ruby actually. Can you do an examination of a Ruby and spinel or even rarer red stone that is clear?
Yep. You can test its hardness. Ruby is red corundum and is a 9 on the Mohs scale of hardness. Spinel is an 8. If the stone is out of its setting, you can also do a specific gravity test, as those values also vary, although that can be tricky, it can be done. You could also purchase a refractometer (30$+) and measure the refractive index as well. Or a dichometer, which is useful to show pleochrosim, or different color shades or variations in gems, as ruby is pleochroic spinel is not. That is because of how they crystallize while they are growing or forming either in nature or in a lab. These are just the few examples that come to mind right now. There could be more ways to test also.
how can you tell if a slice of geode has been tampered with color wise? What are some red flags I bought one and it was a very pretty natural looking blue even my dad who has been into rock a lot longer than I have thought it was real, but two weeks on my table at home by the window and all the color was gone like it was never there, and that window does not get harsh sun either it is very shaded.
I got a small Purpleish blue stone that changes form shiny opaque white too brilliant transparent purple. it also has a almost vermiculite shell coat that i tyhink is causing the drastic color changes.... Its such a weird crystal. it was found in a Creek bed a lot of mineral's and fossils. possible meator strike near by location.... finding alot of green too black glass attached too melted looking limestones.....
I’d like to know a sure way to identify raw sapphires against any similar gems found with them. I’ve bought the sapphire creek-bed dirt bags that contain this dry muddy dirt with a lot of metallic looking fragments but the apparent sapphire looking stones are very different, heavier, dark looking yet contain colour, under light, from green, blue, tan & fiery red. Nothing seems to stick to them & they sometimes have a waxy-like appearance but are tough to grind. Are these sapphire characteristics? Interesting channel you have.
It’s easy for me to mix up my real pearl necklace with my very good imitation pearl necklace that I prefer when traveling. When I reach into my jewelry box, the real pearls always feel cold, and smooth, even if it is very warm in the room. The good imitation pearls, feel closer to the room temperature and almost have a slightly, but not significant, tacky, feeling… Not quite sticky, but not the cold, silky smooth of the real pearls. Has anyone else noticed this?
From your day-to-day experience with real ones; is it crucial that they don't rub against each other or is there a degree to how casual a treatment they can handle?
Made ya look...at this amber. Or is it? 😉 These were some cool tests. I can't wait to check out a gem show in the future. Might take a tip or 2 with me.
Please use a dichroscope I really am trying hard to separate my collections natural and synthetic\treated stones but I've collected decades from various sources so looking for the best tips for separating natural from synthetic...I actually often buyt from j tv collectors since I trust those gems more but some multicolor stones I have trouble identifying
I appreciate the info, so helpful! I am sorry, but I'm finding the music really distracting and unnecessary. It makes it harder to concentrate on what's being said. I prefer the front on camera angles as opposed to the 3/4 view of the speaker.
Oh my beautiful stone I was hoping was real ...is pretty warm. Then I felt my diamonds ...ICE COLD well I'm sad now. Thanks for the "compare to glass" tip though. It's going to be useful
I just use acid when it comes to diamonds and gold. Acid will not etch into a diamond or gold so in a couple of days You will know if it's real or partially authentic. It's just more time consuming! I really learned a lot from Yal! Thank You God
By the way, "refRection" is the bending of light when it travels from one medium to the other, like prizms do, like water does, like diamonds do when light first hits them. Au contraire, "refLetion" bouncing off of the light from a surface, a refLective surface. In addition, it the light travels from one medium like air and hits a tranbsparent but refLective surface, both refRection as well as refLection occur. Some light bounces back at the equal angle but in the opposite direction, whereas some of that light also passes through the other transparent medium and bends or refRects at certain angle, called Refrective Index. And that is different for different materials, based on their density, viscosity, etc.
I appreciate you explaining and showing me , I understand greatly what your talking about ! Thank you ❤️💋🎉 I know more because of you and you friends !...
I've heard, for pearls, you can rub them against each other, you'll feel the resistance in your fingers and if they produce white dust, they're real (but it's a bit destructive)
A common test is also to scratch them gently with your teeth - it should feel fairly granular whereas plastic (a common imitation) is smooth. But it can be destructive and also somewhat risky depending on if the pearl is dyed or has any other chemical on it. :)
There are lots of tests that can be done on gems mounted in jewelry. If it can pass light through, you can try a polariscope. If you have a clean polished facet elevated past any metal in the setting, you can try a refractometer. But, for glass, you can often spot it with a loupe. Look for bubbles. The more stones you look at, the easier spotting it becomes.
I See on tube, gemstones being extracted out of a large rock.. this is in China, or thereabouts. These stones can also be picked up on the beach. There are definitely agates, but the stones are mostly clear and colourful. Some found on the beach have a high chatoyancy like cat's eye. What am I looking at? You can see for yourself by clicking on "Ying" on Tube.
Hmmm...we've seen a lot of channels like this. In the videos we've seen, these "found" stones have a huge range of colors and high degree of polish, which leads us to think they could be a wide range of things, either natural or synthetic.
Why rub the pearls on your teeth? Dr. Lori says don't do that, but you rub them together to see if they are real or not. Plus look at the drilled hole. People who wear dentures/partials can't rub it on their teeth:-( So are you saying that's the ONLY way or can you do what Dr. Lori says and rub the pearls together, if they are rough then they are real? I get jewelry lots in bulk and lately I've gotten what I believe are freshwater pearls in them. I mean almost every big lot. And I love them personally, won't be selling them but if they aren't real I want to know that. Thanks for your help. I LOVE your videos and I just found your website where I can learn even more! Even when you're up in years and disabled? One can STILL learn new things:-) Thanks for helping me do that:-)
The Tooth Test for Pearls looks unsafe, yet I know that Pearls are mainly made of Aragonite which has a hardness of 3.5-4 and your teeth are practically made of Hydroxyapatite which has a hardness of 5.
I love your guys videos I watch every day I’m 10yrs old and I am addicted to gemstones and I make jewelry to and when I meet experts most of the time they learn stuff about gems from me that they don’t know and that’s there career so can you guys make a video for expert +++ about gems because I need to learn more from you guys but I kneed expert expert expert + video so I can learn more.
Your amber test is flawed polyolefins make up a majority of plastics today and ha e a density range of 0.8 to 0.96 g per cc so they will float the hot needle is a more precise test and Amber comes as copal too so you have more than one value proposition
ty for not having a "blonde moment" there and using the sharpie on the white board lol for the second layd tytytytytyty for NOT saying "Expere-mint" lol

Lol I ran to test my diamonds .. they're ICE COLD
...maybe be another reason why diamonds a called "ice"
Try a pawn shop!
@@linkbeast180 that's actually a great idea!

@@Elizabeth912-v6o That's both helpful and rude of you my dear sir/lady, thanksn't?
Do sapphires have a reddish skin? I have one but the light reflects red but shine through is royal blue
The pearl-tooth test is done extremely gently you do not want to scratch the pearls. They just feel like sand paper.
min 6:55 to min 7:19 you make me confused about Amber is it less dense than salt water as you said, then why does it sink?
The genuine amber floated, the fake was the one that sank to the bottom.
What store or vendor is going to allow the customer rub pearls on their teeth? LOL...Hurry, honey they're not looking...😁
You could rub them against each other. If they feel rough and they have a powdery substance between where you rubbed them, then the pearls are real.
None.
The one they own😅.)
When u bite on aluminum and u get that ouch probably means got cavities 😅. )
Rub the pearls against each other. If there is friction (real) versus smooth (fake)

Can you do an examination of a Ruby and spinel or even rarer red stone that is clear?
A ruby will glow red under ultra violet light.
Take it to another jeweler and/or have it sent out to be tested.
Natural Burmese rubies are expensive and rare. Your stone could've been heat treated which improves the color.
Yep. You can test its hardness. Ruby is red corundum and is a 9 on the Mohs scale of hardness. Spinel is an 8. If the stone is out of its setting, you can also do a specific gravity test, as those values also vary, although that can be tricky, it can be done.

Lots of fun and good tests. Thanks!
Would love to be able to use a uv light to distinguish the diffrent RED gemstones.
Thanks.
Unfortunately, fluorescence is not a good indicator of what type of mineral the gemstone is made up of.

Its such a weird crystal. it was found in a Creek bed a lot of mineral's and fossils. possible meator strike near by location.... finding alot of green too black glass attached too melted looking limestones.....
Moldavite is dark green with gas bubbles and it has fallen like meteors do from the sky. Look up photos of Moldavite!
Ty soo much that was the most informative video I have seen soo far!
My gosh. This was so good. Thanks.
Awesome awesome video fantastic knowledge and no equipment needed sweet awesome thank you so much

From your day-to-day experience with real ones; is it crucial that they don't rub against each other or is there a degree to how casual a treatment they can handle?
But, how do you test a gem when it's already mounted in a setting? Like you find a ring in a yard sale, or a secondhand store?
amazing did not know the one with the marker thank you for the video
but at 09:50 you can also put the stone to your face. i always do that. it has to feel cold.
This was very informative thank you.
Made ya look...at this amber. Or is it? 😉
These were some cool tests. I can't wait to check out a gem show in the future. Might take a tip or 2 with me.

This video about testing gemstones is so fascinating and so simple even with objects we have.😯💎🖋🧂💧🔬 Thanks for sharing this to us.🤗

I am sorry, but I'm finding the music really distracting and unnecessary. It makes it harder to concentrate on what's being said. I prefer the front on camera angles as opposed to the 3/4 view of the speaker.

well I'm sad now.

Very informative and so easy to perform. Love the video.
Thanks for sharing this, it was very interesting and informative 👍 👌
These videos are so useful thank you
How do you identify if they are already mounted in a ring or necklace?
How to test mounted stones was shown . Very specific criteria.
What is the large round green stone in the test? Thanks
Is the fog test is any good ??
so if you see a line on a gem with the loop its fake right?
I just use acid when it comes to diamonds and gold. Acid will not etch into a diamond or gold so in a couple of days You will know if it's real or partially authentic. It's just more time consuming! I really learned a lot from Yal! Thank You God

Thank you this helped me so much
The stones are usually already mounted in jewlery, so how can you determine if they are gemstones or glass.
There are lots of tests that can be done on gems mounted in jewelry. If it can pass light through, you can try a polariscope.

I’m so lost “critical fraction degrees “ lol 😂
Please how can I send you .because I have many rocks but i don't have any experience about its
you can rub pearls against each other, if they produce a powdery dust, and yet when you wipe the scratched surface it retains its luster, it is real

UV light on dried up mustard
Yes
The Tooth Test for Pearls looks unsafe, yet I know that Pearls are mainly made of Aragonite which has a hardness of 3.5-4 and your teeth are practically made of Hydroxyapatite which has a hardness of 5.
doing the tooth test on an inconspicous part of the pearl will not really damage it in a noticeable way
Great thank you
What about sapphire stones ?
Obsidian tests please
It’s the same thing as the glass test lol
The point to be made is that a person uneducated about gemstones simply should not try to be an expert about it.
I love your guys videos I watch every day

We're so glad to hear you're enjoying our videos, and that's great to hear how much you love gemstones! Let us know if you have any specific requests!
Ya so I don’t have any specific questions but I just kneed to know more about gemstones so I can enter GIA this age and learn so much.
Maybe more videos like gemologist vs geologist but more expert like stuff with Tim Mathews and the most experts in jtv
AND THANK YOU
😂
Hello. ...🖐I am from 🇱🇰.I have blue crystal sapphire (natural)😃
Subscribed and liked.😉
Thank you
Very interesting
The only problem is most ppl are buying gemstones already set on metal(jewelry ready to use). These test won't help.
What is with 3th Teeth.😅
Can my Grany do the Pearl Test ?😂

Cute pretty lady Elizabeth 🥰😘👌🏼
What did I do before finding this channel? 🤔
I have a ring in a setting and I don't know how to tell if it's real.
சுப்ஹானல்லாஹ் அருமை
Elizabeth sure does say "oh, queso" alot huh..
Pity no 'tick' or 'cross' showed during the pearl test, so... was she right???
She was!
pleas identify saphires.
❤❤
I really thought the tooth test was just something the writers made up on M*A*S*H
ty for not having a "blonde moment" there and using the sharpie on the white board lol
for the second layd tytytytytyty for NOT saying "Expere-mint" lol
🎉🎉🎉🎉
I can you look at a stone for me and identify it
👏👏👏👏
Hmm maybe i should buy myself a loop also
Did tell how to tell a fake opal form a real one.
CZ is cheejee, I no wan'
🌌
Je veux tout et plus encore..
Why don’t you just say Cubic Zirconia?
You could use your nails instead of teeth
You are just beautiful
U sound like u r about to cry
The very first lady
No offense
Stop saying ‘super’ for describing everything. It’s ‘super’ distracting and annoying.
wayyy to much talking ....
😂😂😂 SMH…
Found the channel, fantastic
Dear God, either teach a lapidary class or follow through with the tests.
