We love testing gems. Did like seeing these tests? Would you like to see more tests in the future? Let us know!
You guys should do a video on the complexity and variety of Feldspars! Read my comment I posted and you will see why that is a good idea.
Also thank you for posting videos on gemstones I love gems and minerals, mainly gemstones though.
Yes, please do another test video.👩🏫💎
If like to see the crew try the visual optics technique. It allows a person to see the electromagnetic spectrum with no tools but the gem and a specific light source. When you see it ,it's AMAZING. Check caver461 visual optics video for a good detailed explanation of what it is and how and why to do it.
I like the trinket...I take it!I really don't care what it is.
This opal make me invisible...
what book is being used in this video?
I can listen to her all day talking about anything she has a really calm and beautiful voice
Incredible teacher. Very clear, very understandable. Learned a lot in a small amount of time, thanks you so much for that.
❤ I absolutely love her accent. She is so elegantly refined. I could listen to her talk all day
These ladies do gentle data transfer.... Please do more!
I really like the Learning tools that are used in the demonstrations used on this video. Thank you very much! 😊
You're very welcome!
This is fascinating. I love the videos that show some of the scientific side of gemology. Thanks for sharing this.
Clear and insightful tips and observations from a very talented gemmologist. Thanks for making such an excellent video.
That was a great video demonstrating some of the key points of Gemstone identification. You can never tell from a digital photograph what you are looking at, that’s why testing is so important. From my experience, Specific Gravity is quite a precise science so you have to be very careful or you can be way out. Thanks Sam & Rebecca for another great share. 😀👍 from Wales 🏴.
Yes.
Shes got the most adorable voice and accent ever and shes just adorable 🥰 good episode also💕
@Raul Banegas ha!
Y’all make a great duo
Feldspar and Quartz are quite literally the most variable and complex gemstone species in the world. That includes for Quartz: Chalcedony/Chrysoprase, Quartz(Lemon, Lavender, Amethyst, Smoky, etc etc), Tiger's Eye, etc. For Feldspar: Moonstone, Labradorite, Adularia, Amazonite, Sunstone, Afghanite, Sodalite, etc etc. Quartz has variety in terms of formation, and Feldspar has variety in terms of there being so many different sub-species such as Microcline, Plagioclase, Oligoclase, Anorthite, Albite, and a few others and they form different varieties of Feldspar depending on the type of Feldspar layers that form on top of one another. You could have Oligoclase layers, Plagioclase layers, and Orthoclase layers all stacked on top of each other and that could be the reason there is schiller on two or all four of the perfect cleavage sides and I have even found clear white Feldspar that has schiller on the two imperfect cleavage sides.
That is why Quartz and Feldspar are in my Top 10 favorite gemstone species, Feldspar is probably my #1 all-time favorite though.
Edit: by the way I don't have an education and haven't even graduated high school yet (working on it online though), I have just been collecting gemstones since I was 5 years old so I have gained a lot of knowledge of gemstones over the last 20 years. Not only that, but you can simply go online and read through all the different articles and you will retain all the information and be able to sift through the misinformation, so long as you actually enjoy gems and minerals. That is how I know so much, though.
Good for you. Keep up the studying, I find it’s an amazing & interesting hobby to combine as a skill. Hopefully one day Tyler you will become a great Gemologist. Remember, a good Gemologist is always learning. Best of luck for your future. From Wales U.K. 🏴. 😀👍
@@rogerhargreaves2272 Where I am at right now people don't want to see me do well, they disrespect my grandmother and abuse the animals she saves and pays to get fixed and pays for their rabies shots, and they make stories up about us. So if I want to do anything I have to move to a different state because this gated community is full of aggressive cowards and karens who don't know how to fight and have mental issues or something.
Someone even tried to poison me while I was taking a nap on the front porch.
As long as you don't give people too much trust you will be alright, remember that.
Also I haven't done anything to anyone, people are just aggressive and cowardly when it comes to people who live in gated communities more so than anywhere else I have seen in my life.
This neighborhood is so toxic it literally made me not like humans and has changed my outlook on the world. Other than that I am doing pretty well. Thank you for your support and I hope you have a good life and be kind to others.
@@Nervii_Champion - Sorry to hear about your circumstances, it sounds like your neighbors are not very nice at all. Concentrate on your Geology and Gemomogy, it will help you mentally and you will do well in life. 👍
@@rogerhargreaves2272 I am actually trying to join the US Army and go to RASP and Ranger School because I want to be in 75th Ranger Regiment, which I have also wanted to do since I was about 5 years old. I have also been shooting and fighting since I was 5 years old so I may as well put it to use taking down ISIS guys or some other evil men.
@@Nervii_Champion - Hey Tyler, do it my friend. You really do have multiple skills. I think you will go a long way in this world. Just keep safe. Rog. 😀👍
That was absolutely lovely and informative.
Thank you so much for sharing your knowledge and making this video. Spot on for sure. ❤
You have a lovely voice, Ms. Lloyd, very pretty and soothing.
Great knowledge share for gems.
You guys are just awesome. I learn a lot at Gemstones.
Neeed that measuring gage
As a novice GG myself I always love watching these videos. Also, do you have any resources on where we can purchase these instruments used in this video specially? I’d love to be able to do this test at home. Thank you.
You can find a millimeter gauge and scale at JTV, and Gem-A also often sells kits for measuring specific gravity.

@@gems thank you so much. ✨
Love the video! 👌😃💎
That was great!
I love it thank you.
How can you tell if Tanzanite is real or fake? Please. I don't have the machine for refracting. Will water work for the doubling effect? Thanks. What kinda books do you recommend for all stones?
It's so incredible to see the technology🔬⚗ that are used to identify gemstones.🙎♀️😀💎 I find it very interesting that you have know the length, scale⚖, water density and of course math📘✍➕➗ to know each gem like to tell the difference🤔 between diamonds💍 and cubic zirconia💠. Good video and thanks for teaching and showing us these devices.👩🏫🙂💎
Very interesting 😊
Thank you 😊
thank you
You're welcome!
I have a question! Why isn't just volumic mass used instead? It seems easier to me to calculate. It's just mass in air on volume of water (by displacement). Maybe it's less precise, but it's easier I think
Where can I buy a rig like that to weigh stones in water?
That’s super-dee-duper!
Is there anything in North Texas worth trying to find?
Nothing...
9.3 coming from?
My total weight (14.14+12.11)/2*13.125*7.19*3.52*.002 is 8.72... How did I get my math? Educate me please.,
Rebecca is more beautiful than any diomond in the world..Love you from indonesia
I’m really confused, doing it this was drastically changes the results, as a pose to just dividing weight in air by weight in water.
Eu tiro a medida de densidade em água comum o que manda é a calculadora a minha calculadora da uma diferença de menos 3 pra mais de 4 até o 9 descobrir através do crisoberilo
My goodness she reminds me of Myrtle from harry potter.
Gj ladies :)
Rebecca is beautiful 😍.
😃🇧🇷
But how do I ID a stone that's stuck in a ring 💍
Probably have to remove it. Take it with a grain of salt but selling jewelry seems to be better separated. Sell gold separately from the gems unless it's some amazingly beautiful piece together then don't mess with it.
Matpat sent me
If you don't mind where is 9.3 coming from?
My total weight (14.14+12.11)/2*13.125*7.19*3.52*.002 is 8.72... How did I get my math? Educate me please.,
But thats just a theory.... a *gem* theory
1st
nobody cares
