[Gemstone Secrets] How to Avoid Glass and Acquire Gems

[@ckcarruth]

Buying a piece of glass is "humiliating and impoverishing." Well said!

[@GemologyforSchmucks]

XD Glad you enjoyed it Cheryl~

[@slwtgf]

Very true initial statement! I’m praying my chrysoprase ring is NOT glass …. Oh please oh please ….

[@ohcar0line]

I’m having the time of my life learning from your videos!

[@GemologyforSchmucks]

High praise indeed~ thanks

[@MandyWoodArtist]

What an awesome teacher you are - really educational and a little bit funny to keep it interesting .

[@GemologyforSchmucks]

Thanks Mandy~ what a fantastic boost this morning :D

[@degenerati]

I buy a lot of antique jewelry online which can be tricky. I always ask for additional pics , and ask if the seller has used a gem tester on the piece. It’s amazing how often I’m sent glass by a seller who has told me that they used a gem tester on it. I don’t even know how many times I’ve referred a bad seller to this video. I always hope that it helps somehow. Your vids are really great, Peter !

[@GemologyforSchmucks]

Thanks ~ i'm glad that my work is of service.

Very helpful video, Peter ❤. In "The Crown" there's a scene where Prince Philip's mother, Princess Alice of Denmark and Greece, now a Nun in Greece, attempts to raise funds by selling her huge Ceylon sapphire surrounded by diamonds. The pawn shop "jeweler", tells the elderly nun no real sapphire is that large. She doesn't argue, but confidently replies, "Test it." Pawn dealer then gets what appears to be a regular pair of glasses and carefully examines the jewel. As he begins to see it may be authentic he takes the sapphire, holds it near his mouth and exhales on it. I am just wondering what information the "technique of exhaling on the stone was supposed to reveal? (The Crown, Season 3, Episode 3 or 4, called "Bubbikins" approx.10 minutes into episode.)

Generally gems tend to feel a little cooler/colder, when you try them on your upper lip (heat sensitive area). Not a valid way to determine if it's really glass or not, but a simple little trick that doesn't require any tools :)

[@richipdaman]

Thanks a bunch! A very easy and straightforward video, looking forward to learning more 😊

Thanks again for an interesting and educational (and fun!) video. I would like to have seen in your video a few good pictures using the dichroscope on glass and then showing the differences to tourmaline or sapphire or garnet (and yes I remember it does not split light) but examples would be really helpful.

[@GemologyforSchmucks]

I appreciate your feedback Don. I agree that some glass or other SR gem photos would be an improvement. I think i was more laser focused on showing some examples of how the colours could look different when sampled from the same spot on the stone. If you'd like to reach out to me on Instagram @obscurventure, i'll get you some pictures of dichroscope with some SR stones and glass.

[@KevinMcLean]

You have amazing camera skills! I make films as a hobby and focusing through small spaces not to mention light bending pieces of glass is super hard!

[@GemologyforSchmucks]

Thanks very much~ it is indeed tough to keep the camera steady, and also take meaningful shots with such focal lengths. I appreciate that you recognize it XD I'm still striving to do better each time I shoot.

[@OmeletTwelve]

Just found this video last night. Watched it twice. :-) Boring? Hardly! Your fun approach makes these kinds of things easier to memorize. Now I'm on my way to chase down the rest of your videos. Thanks so much for being willing to help us hobbyists learn this stuff! I want to create inlaid Art using gold and real gemstones so this will help my craft a lot. I'll save money by Placer mining the gold. lol Cheers and thank you again!

Thanks teach ! Appreciate the very clear explanation given . Here's an interesting but irrelevant comment. On a rainy evening when raindrops are tiny, like fog, the lamp light appears pink. It's quite romantic when it falls on the loved one's skin. Do you know why this pink effect happens ?

[@GemologyforSchmucks]

I'm not sure that i've seen pinkish fog. My first inclination is to wonder about the lamp itself.

I want to this one

[@neelandrennie8791]

I've a blue cute gem 💎 and when I shine my black light on it, it turns the gem 💎 into bright red weather in darkness or daylight... Can tell me why this happens please?

[@GemologyforSchmucks]

Hi Neeland, Without knowing more about the stone, I can just guess, but i'll say that UV fluorescence reactions are typically caused by either Chromium or cobalt. Natural and synthetic stones both can have these elements in them, and the intensity of the stone's reaction is usually related to how much of those elements are in the stone. Cheers and thanks for the question

[@irshadahamedirshada9385]

Sir please explain how to identify taffitte...

[@GemologyforSchmucks]

Id suggest going to a database either online or in a book and checking out the characteristics of Taaffeite. We identify gemstones by using these characteristics such as the refractive index and birefringence and testing them with instruments such as the refractometer. Best of luck to you.

Good job Peter brother, love and respect form Pakistan

[@GemologyforSchmucks]

Thank you Nakaam, glad you enjoyed.

[@roberthamblett9619]

Excellent and informative as always..does this mean at certain angles light could reflect through the gem from the back or sides and be partly polarised creating false pleochroism in the dichroscope

[@GemologyforSchmucks]

Thanks Robert~ To your question: I don't think so, but i'm not a physics instructor. My understanding would be that the stone has pleochroism due to its doubly refractive nature, and if you look from the optic axis, it will seem singly refractive. A singly refractive stone shouldn't somehow become doubly refractive unless it has some ridiculously large doubly refractive included mineral (bizarre but technically possible) or dark wizards are messing with us XD. Again ~ we'd have to check with some of those Ph.D's to really have certainty on this one, but my gut says "no".

[@roberthamblett9619]

Thanks for the fast reply, I was just thinking of the reflections from water example and wondering if the reflections inside the gem could act the same, partly polarising the light reflected back through the scope jusy making a slight lighter/ darker difference. But I think maybe you are correct and it wouldn"t make such a difference. Thanks

[@jerrybowers2119]

Cubic Zirconia Glass usually has bubbles

[@GemologyforSchmucks]

The manufacturing process is a key part in that. As a rule, I try to avoid the word "usually" with gem identification, because it may work often, but when it doesn't... it bites hard. My recommendation is that we stick to what we can prove definitively.

[@peanut924]

I need to know if my garnet is real or glass! What should I do?

[@GemologyforSchmucks]

The best thing would be to get a refractive index reading, and then depending on what colour the stone is, the next thing (or even the first) i'd go for would be the spectroscope. Pyrope-almandine and spessartite all have diagnostic absorption spectra

[@sue3519]

i am starting a business and i want to design gold pieces with real gemstones but i am finding it difficult to learn gemmology just to be able to buy real stones 😅. what’s your advice? do i have to hire a gemologist? or try doing it myself? 😟🤔

[@GemologyforSchmucks]

Hi Sue ~ certainly, learning about gemology will be the long road to success, and it's not a requirement as long as you have a trusted source. A big part of what I do is source gemstones from the market for my clients. We also have access to gem labs here to get 3rd party reports for significant stones. If you'd like, send me an email at [e-mail] and we can discuss the details of what you are looking for and the best way you can go about getting what you need.

[@johnnyllooddte3415]

so?? does light cause 2 colors or not.. you danced around that one

[@GemologyforSchmucks]

Hi Johnny, pardon the confusion. The beginning starts with light. A natural source of light such as noonday sun, or certain other substances burning hotly enough will produce full spectrum light. That means that there are all the wavelengths necessary to create all the colours we are capable of seeing. What the gemstone does is filter that light, absorbing whatever wavelengths of light it is able to, and reflecting back to us what the crystal rejects. Some gemstones have different optical axes (doubly refractive stones), so one direction in the stone may absorb some wavelengths differently from another direction of the crystal, giving us a characteristic called pleochroism. So the shortest answer is: no, light does not cause the multiple colours (2 or 3), the way the crystal absorbs the light is what gives us the multiple colours. Thanks for the question and I hope this clears up the issue.

Yes indeed, it's correlated: scientific progress and understanding only happens in the presence of coffee.

[@brianterence3211]

@@GemologyforSchmucks How right you are. Correlation does not mean the same as causation. My favourite example is that among all children, the size of the big toe correlates with their intelligence; the bigger the toe the higher the intelligence as measured by intelligence tests. Does that mean big toes cause high intelligence ? If you say yes I will know you have a small big toe.
