This is really interesting. I've always been fascinated how ancient cultures cut and polished gemstones and made jewelry. I'd really like seeing you delve deeper into this.
I would have liked more detail on the ancient history. Engraved gemstones with detailed and often beautiful pictures were very popular in the Roman Empire.
That was a really good quick history of lapidary! The earliest known examples of ray tracing to achieve maximum light return was done on paper in the 1930s in the US and probably the most important step in creating a truly brilliant SRB.
I was at the edge of my seat just waiting for one of you to mention the refractive indices of the stones. Good job!! I thoroughly enjoyed this episode💎❤🔥
Rob mentioned a perfect example or how it all got started, rounded stones. Natural cabochons that just need a chain or string added. I have several that are exactly that. Very interesting gemstones episode. Thanks!
If you recreate the point cut and table cut in GemCad and GemRay, they actually look a lot better than I would have expected for how simple they are - there's actually some brilliance and dispersion. It's no round brilliant, but it looks cool.
Please tell me where Natalie went? I love all you guys, I remember when rob first showed up to get his geode cut. Please, where is Natalie, is she okay? It’s bad enough I had to search for Elizabeth and find out way later she was well in Arizona at an awesome job.
In addition there's another cut important for diamond industry, 201 facet patent cut designed by coster diamond house, one of the oldest in Europe.. Gives out much more luster than the brilliant cut.
next time, could you please allow Brittany to speak? She could have contributed a lot to the discussion (or...maybe we should just call it Rob lecturing experts for the audience???)
India? Not in the America's? Well then, Chert Arrowheads, are 14,000 years old, & yes Quartzasite hand knives, are 720,000 years old,; yes from North America!
“Let’s have Brittany participate for eye candy.” Her annoyance is evident by the eye rolling and foot tapping. But we’ll let the mullet speak and interrupt her instead of letting her contribute. Sad.
Tiresome young people climbing their woke soapboxes.. Brittany never stops moving her eyes and feet and she’s obviously as knowledgeable as Rob and it’s routinely obvious that Rob knows and respects that. And what might be worse than making an obvious joke?
@@timothysullivan6790 "woke soapboxes?" please go take a nap. Brittany hardly speaks AT ALL in this video and it's frustrating, AS A VIEWER, to have her sitting right there, probably with lots of info and insights to contribute, yet she either isn't given the conversational space to talk, or, if she was, the editors of the video have for some reason deemed what she had to say to be not valuable enough to be featured in the final video-- and BOTH possible reasons are offensive at worst and very rude at best.

I always learn something from you guys! Thanks for the gem history lesson. Enlightening as always!
I was just wondering about this very topic! the history of gemstones and humanity is fascinating, thank you for the informative videos as always!
I was at the edge of my seat just waiting for one of you to mention the refractive indices of the stones. Good job!! I thoroughly enjoyed this episode💎❤🔥
Thanks for putting up with the couch to be eye candy...
That cat sitting in the middle keeps giggling. 🐈⬛
My favorite cut is the Cleopatra's eye!! 😍😍 Thanks for the lesson!!👍👍😁
Love the cat ears
Great vid as always but I would have like to hear a little more about Old Mine cuts and Old Euro Cuts specifically.
Rob mentioned a perfect example or how it all got started, rounded stones. Natural cabochons that just need a chain or string added. I have several that are exactly that. Very interesting gemstones episode. Thanks!
I'm here for the history!
Thank you for sharing your knowledge with us, we’re are learning a lot from you guys ❤
I have great respect for gem cutters because I have tried it myself. Much harder than it looks. 🔷
I learned a lot, thank you! ⭐⭐⭐⭐⭐
Interesting…thanks . Love the cat shirt 🥰.
Doing a catch up on your vids, amazing as always 💖

Very informative and super interesting video 🤔🤔🤔 Thanks for sharing
Buenos días team. Good episode ❤ 🇦🇺 🇨🇱

Natalie is doing well, but she no longer works in the gem industry.
I just bought an 8.6 carat andesine, and would like to see a video on that. Thanks
Thank you Guys. A really interesting video. (But not long enough 😊). I’ve always wondered how gem cutting began. 🇳🇿
In addition there's another cut important for diamond industry, 201 facet patent cut designed by coster diamond house, one of the oldest in Europe.. Gives out much more luster than the brilliant cut.
Thanks
Wow! Never knew why the culet was flattened. I guessed the stone was too long and was poking the wearer. I like yours better.
Yay Dalan Hargrave!
Has to be one of my favorite videos
Iron sharpens iron
The rose cut is back. It looks like bubbles around a center stone.
Hardness and durability aren’t the same gemstones properties. Hardness is about the scratch resistance and durability is shatter resistance
By your definition of “Faceting” you’d have to give it to arrowhead making by early man, no?
No black background? Weird. I'm uncomfortable. 😄
Why you have the other two people if you want only you to keep talking?
I agree, to me it came off as straight-up rude, even though I doubt that was the main speaker's intention.
If you want a morganite without brown extinction, buy a John Dyer cut
🪨*Q:* Why did the little gemstone wanna go to prison?
💎*A:* _Because it heard that's where you go to get cut ..._ 🔪🔪🔪

I want to sell my collection.

I thought you were going to get a haircut bruh?
Well, judging by the response on the last video, rob may never cut it again!
