I absolutely loved this video! Highly informative, perfectly explained, useful graphics and photos, good pace: amazing job! Thank you so much and thanks to Mother Earth for creating such stunning works of art!
Just the second video I've watched from GIA Knowledge series and I'm so impressed with the speakers and technical level of the content. I'm a big fan now. I'm not a gemologist, or geologist, but as a chemist I'm fascinated by all the sciences. More please :)
Stephanie, played this song for me while i was in Ice's, kitchen cleaning. I could only hear throw wall so i walked into livingroom area but i was drawn by the vocals and listened till she interrupted song asking sternly what i thought. You remember that day i hope.. i will never forget it. Can't thank her enough for pushing this in my face!!! 😆😍
This is awesome video as gemologist I watch every GIA TH-cam video and it expend my Knowledge a bundle of thanks 🙏 for GIA for such a great opportunity
Yes, my Mom, Robin Fishburn found some of the largest black tourmaline crystals, in the state of California. This was according to all the local dealers & shop owners in the Madera County area.
Thank you so much for all these Zoominars. I am a GIA alum in the GG program and I am still learning so much. I am a night owl jewelry designer/metalsmith so 10am PST is very early for me. These Zoominars get me up in the morning. :)
Am i to understand that my sample of pyrite underwent the same incredible journey towards it’s formation that a sample of emerald has undergone? But with much more ingredients to work with along the way, the pyrite is much more common? (Referring the the emerald and pyrite samples found right next to each other in the sample photos) Good because i like to stare at my gemstone and appreciate it’s age and it’s journey, but can’t afford emeralds:)
Thanks a lot for this excellent talk. IT's very informative and easily understandable also for a layman like me. However I've a question: I recently heard that Newsealand is the tip of an indivual plate in the pacific area. Is that correct?
I'm in love with colored stones, but am concerned for the durability of some. I am curious about the loss of color in Larimar and the ability of Ethiopian Opal to endure bumps & nicks. Also how to care for Burma rubies.
@Jo Stallworth I'm no expert, but I have listened to a lot of experts on gems. Basically it's science, the harder the gemstones on the Mohs scale(diamond, sapphire etc) are, determines how they are going to take wear better than say opal (5). That said, if you wear your stones every day (wedding ring) all stones will eventually nick, chip and /or crack so you are going to have to repolish them every decade or so no matter what, maybe sooner. Also, ultra sonic jewellery cleaners are good for most gems and jewellery, but some don't fair well so Google or ask an expert about your specific piece. One more thing. Opals are sensitive to oils of any kind, and it may permanently damage the color or luster so keep your opals away from oils and clean after every wear. I do also believe that if your opal gets wet, it may lose its color or brilliance until it completely dries out sometimes 1-2 weeks, but should come back after that. That may also happen if you get your opals hot(that may permanently change the color too I'm not sure about that) so keep them out of the sun and heat. I hope this helps, I'm not an expert but I do listen to them and thought I might be able to give you some sound, quick advice while you wait for the real experts to answer. Good luck!
I've came across a large green mass that look like an emerald by the shape of the crystals. It loaded with small holes the size of a pen head. It could be seen with the naked eye. So I rejected it being a real emerald. Now in this video I see your specimen has hole formed by fluids. Are we seeing that emerald under a microscope or can those water makes be seen with the naked eye?
I have much verious kind of rough ston can be dimond ! I want sell it with proper way , can you help me ? Another thing that , have much magneted ston like sky rok also . different types of colour , so wish you help me.,*
I feel like I may be a bit old to start chasing dreams now but I can't deny this curious fascination of mine a chance to grow and at least try to learn about what fascinates me. GEMS GOLD ROCKS DIAMONDS EARTH....HISTORY HOW IT ALL COMES TO BE WHAT IT IS. I have so many questions. Does anyone feel the way I do? I want to figure out things that no ever did before. But I don't have and never will have the finances i would need to be educated
I am a certified GIA gemologist and the geological formation of gemstones is very very well explained in this video.
Can you provide me with your email address here sir
