I knew I'd eventually see you on here Justin .

[@JustinKPrim]

It was my new years wish. I guess the new years fairy granted it. 10 times 😅

[@Silverity]

That 7-sided sapphire is gorgeous!

[@AJShiningThreads]

Learning the history of the cuts was fascinating - so to speak

[@scottpeters5624]

Justin's cuts are amazing, and the history of diamond cuts was fascinating. Thanks guys

[@TheFacetedFeline]

So interesting to see gems from a lapidary side. Thanks for the education as always!

[@soomcire]

Great episode! Justin’s attitude toward faceting and it’s history has been a big inspiration for me, as an aspiring cutter!

[@JustinKPrim]

😍

[@raeleenrobinson5749]

Love your chanel Justin, I personal could listen to you for hours. Love your work. Keep it up. Cheers.

[@canadiangemstones7636]

Justin K. Prim is a fantastic teacher; I highly recommend his book and YT channel!

[@hannagyllensten475]

Really like that science-aspect of it! Thanks, awesome episode

[@oscarmedina1303]

Fascinating episode. What a great way to learn some history and process of cutting.

[@benjamindejonge3624]

Wooh 3years in gem cutting and wright already a book, you’re a genius

[@lucycabana9970]

This is one of my all time favorite videos about gems. Thanks Justin.

[@LostWithoutHer]

I've been nerding-out on the optics of light play ever since I heard the expression 'table effect' when comparing diamonds to diamond simulants as a teenager. The Moldavite specimen is awesome. I'm visualizing an 'S' shaped finished gem with two separate step cut coned pavillions each with step cutting along the crown and pavillion. Pie in the sky?!? 🤔

[@JustinKPrim]

I would call that pie in an alternate universe 😅

[@Algoldprospecting]

Justin is awesome gem cutter

[@chasecarlson4900]

I own some zandrite myself! My grandfather got the pair years ago and they change from soft green to cranberry red. Super cool pieces and since I can’t seem to find any more that have that color change they’re certainly quite special pieces.

[@kiro9291]

6:45 that seven-sided one is my favorite, hands down 11:25 cube!!!!!!!!!!!!!!!! 16:04 oh my god, yes

[@STRAIGHTJXCKET]

I am in love with this first cut. I wished that we still cut stones this way. The high dome add so much character and the removed tip adds another window of reflectivity all around. I am in love with this cut

[@desilu6657]

I met Justin a couple weeks ago, he gave a presentation for our local rock club.

[@gmariet1391]

Goid guest teacher !

[@HeartTurnedToStone]

Can't wait to see what he does with that Moldavite.

[@gginpar]

Excellent

[@gamorleo3569]

Amazing specimens!

[@selfretired3025]

Nice Moldavite! :)

[@DB-zp9un]

[@gems]

Thank you! 😊

[@troyblueearth7450]

I don’t see any guest info in the description. I was hoping to find his social media and look into that book a little bit.

[@gems]

Our mistake! Added now

[@lorawaring883]

wow

[@reinhardstrickler9666]

Hi Justin Where can I buy your book, teaching of gemcutting? Many thanks for answering.

[@gems]

Check the links in the description or go to justinkprim.com to find the book featured in the video!

[@honorvaziry3381]

Where is Mr. Justin’s workshop, can someone help me please? I have some gemstones to cut and sell.

[@stevenfashionstylest]

Pls I have a row diamond for sale

[@user-se7dn9px4m]

สนใจของผมไหมครับหินอุกาบาตเพชรดำ

[@TuongDaPhongThuyCaoCap-nk5bu]

ok

[@mman6283]

Calling color change glass a gemstone is crazy😂

[@reidrayfield6685]

??

[@mencobagear5874]

The editing of this video sucks. It's not in sync with the stuff he said most of the time. He said something, but the visuals dont show it, or too far to be able to appreciate what he said. Eg, whats the point of showing 2 hands, when he was talking about the effect of modifying emerald cuts? Who cares about their hands? You guys are wasting a quality guest.

[@sandyroo1980]

He should carve a cameo, or face. The faceted stones just don't seem to pop
