Exactly what the titles says and very clear cut explanation (pun intended) TY!
Very nice
Hello! I’m a 22 year old gem cutter from the Americas. This video was super helpful thank you! I’m still new to gem cutting but this helped me with better ideas on how to compare my custom cuts to commercial cuts. I’m incredibly ADHD so I won’t take not perfect for an answer if I can avoid it! Haha currently re cutting the crown to the whirlpool design because I made a mistake😪
Thanks again!
You're welcome... happy to have helped.
I too am an ADD'r (ADHD Adult Residual Type to be exact. LOL).
I hear you regarding being picky if not a bit "anal" about getting the meet points exactly right. I won't settle for anything less ... although I have had to a couple times.
After 3 years using a 60 year old Graves Mk 1, I just upgraded to a brand new Ultra-Tec VL Classic (Digital) just this week. I haven't even finished my first stone on it yet but I already love it because it is so much easier and faster to make accurate cuts and to repeat "goofy angles" (anything past the decimal) compared to using only 1 degree increments on the Vernier Scale.
It pays to take the time necessary to cut a stone well to eliminate Windowing and Maximize Colour Intensity, Carat Weight and Brilliance.
I think crooked lines are an obvious sign, but I never thought about the window. Very informative indeed
Thanks! Happy to have helped.
We're really pleased you like the video and found it informative! :) I'm in the process of making another short tutorial on Oregon Sunstone...unfortunately not a birthstone, it is still an extremely fascinating gem. Anyways, if you're interested I hope to be done with it by the end of next week...approximately!
Still holding my breath for your Oregon Sunstone video
@@gfaraghan It will be up soon ;)
Very well done John! It is nice to see you offering such incredibly easy to understand and well illustrated information.
Like your gems, your video is beautiful!

Thanks for sharing..love to learn how to identify the good cut and bad one!
Great video for newbies!
Thank you for this video!
a tutorial on Oregon Sunstone will be very cool, hope to see it soon!
As a geologist I don't fully understand (by heart) why to take so much natural beauty out of most gems by cutting away their history (of their birth/creation). However, this video was still quite informative and easy to understand as it gives simple tips which even people like me can easily apply next time seeing a cut gem. Thanks for sharing.
to help you understand a little better , would you want your gf to not shave her legs or underarms ? just kidding

Yes, I (would) want her to be proud of her natural beauty. For the sake of a different look, too many people are inclined to sacrifice part of their own person(onality) or that of e.g. an object like that gems. That's just my opinion. I understand that the optical effects you can achieve are intesting in a way, however, you almost totally negate the gems background that way, the chemical fingerprint set aside of course.
in my opinion its turning that history into beauty so it could be even better appreciated by the rest of the world for centuries
Its history is also on the inside, I think you'd agree. Even when cut&polished, every gemstone remains unique and its history is still in there. Polishing it allows us to see what on the inside.
But I can definitely understand the geologist's perspective.
I love gemstones, and I collect them as a hobby, but I'm equally interested in meteorites and nuggets of metals, for example. On the other hand, I also love pure metal bars.
I guess I see both perspectives.
Not many rough specimens are rare, unique, or interesting enough to warrant preserving their "natural" beauty. Cut gems are (or should be!) pieces of art similar to a sculpture cut from a block of marble.
Thank you. got it, window, meet points, straight even girdle, and polish.☺👍☕
;) 👍
Although there are rare exceptions ie. a window in and emerald to decentuate the vvs inclusions in the center; this educational video is just what the trade should be more aware of. To take the idea from Ty, this video is a cut above. Bravo!
Hi Faud,
We don't offer classes on cutting, just trying to educate everyone one what a well cut gem should look like.
Regards, John
Is there anywhere we can turn to to get our gems properly cut in your magnificent style? I have a beautiful VVS clarity platinum-peachy pink morganite purchased from Afghanistan, but it does have a small window which takes away from the stones beauty.
Good detailed video, explaining how to add more value in stone by faceting quality.
I also take care same. I look artistic gem cutting in RMC Gems.
Great video! Thank you!
There is very valuable informations. Thanks alot
You're welcome!
Very informative
thanks for showing well done
You're welcome!
I by myself have cut a emerald cut on a Quarz yesterday and had to recut the 4 facets which meet at the Centerpoint of the pavilion from 43° to 35° because I broke it while polishing (chipped at the holder of the lap). You can clearly see a window now (if you know what you are looking for). Also some of my gems have poor meeting points here and there but it's not because of fast working but because of the faceting head which is not so accurate in terms of precision unfortunately. I'm sitting 10 hours + sometimes on one stone, but I'm limited to the tools I have.. You have to start somewhere right? Also, the majority of my customers love to buy handmade jewelry, as long as it has fancy glittering to it. Private customers most likely don't give a s*** about precision. But That doesn't mean that I don't care about a good cut. More sales are meaning more money to invest in better tools. :)
I really thank your I leaned allot I think I have a lot of junk from now on I will look better and be more satisfied
Happy to have helped.

You're welcome
very informative :)
Thanks!
Welcome! Hope it helped
nice
Thank you!
Thank for a good v d o
ขอบคุณคับทุกคนโอเคเยี่ยม
There are two ways of cutting ...the bad and the good..gift is already given but learning comes from experience...gift is fast but experience need more time and faillure
Do you offer faceting training classes?
Great video love it 😎👍💯
thanks
Nice video
I think you have confused a few cuts. A traditional princess & emerald cuts (0:55-2:07) and modified step cut and what looks like concave(millennium 5:07) cuts. totally different cuts. Traditional emerald cuts are to highlight a perfect (flawless) material. True the faceting needs to be at proportionate angles to be correct. It's easier to hide mtrl imperfections in in some of the cuts you highlight. What you re saying always holds true to diamonds not always to colored stones I don't think your being completely fair..It's unfortunate not everyone has $800 for a fine cut common topaz .
Very interesting video
Almost certainly the best cutter in the world... and a nice guy! What more can you ask for?
Thank you! :)
Wow! You explained that so well - thank you. We have just started fossicking for zircons in Australia and have got 100s of stones, but we are clueless as to which ones will cut well & who to get them by. We were advised to use a company in Thailand, but other people have told us to get them cut by a good gem cutter here. Any tips on finding someone who can cut well?
Hi Emma, we don't know any one in Australia who can help you there, but we do know someone in the US who can help you, if you want we can send you he contact
@@JohnDyerGems hi John that would be great, if I can’t find anyone good here :-)
@@emmafifield2400 You can contact chriswolfsberg.com/
Thanks so much john :-)
@@emmafifield2400 You're welcome. ;)
I just want to know what cut those blue gemstones are in the thumbnail @John Dyer
Wee call it a Starbrite cut.
Great video and very informative. Hats off to ya
Thanks Michael!
Highly interesting and informative, thank you.
welcome
this is very2 good
thanks 😉
Now we know
;)
I needa be very careful cutting gems. thanks. This is going to be useful when I facet an Alexandrite.
Oooo.... yes! Lmk how that goes. I have several Alexandrite pieces and i very much enjoy them.
No se que significa eso de los diamantes, pero hize el comentarios.
Total internal reflection, the old classic... ;)
Andy Web thanks! 😊
John Dyer Hi John. Is it possible to make a living faceting stones?
This is why I like chatoyant/Asterism/Cat's Eye cuts. All you have to do is dome them in the proper direction, like Moonstone/Sunstone Feldspars or Star Sapphire/Ruby Corundum.
Fantasy cuts and Cabochons are what I like personally, I don't like the thought of perfection in gemstones. Perfection is boring.
Hi 🧡❤️
Hello
There are countable cutters in every country.
How much does it cost to fix?
We don't fix gemstones, but if you want, we can refer you to someone.
So that means
Good Gemstone no reflection?
Bad Gemstone have refection?
