The sheer concentration and patience an artisan needs to get the stone to look so beautiful is what makes it many times more valuable. Amazing work!
Well said it takes much more time to cut gems to this quality
gonna be a shame when some techbro decides CNC cut gems needs to be a thing
@@trippcailean9594 Machine cut gems are already a thing.
@@stuartgems7593 a quick question, do you cut a part of a larger rock to suit the shape of the gem you make? or do the rocks come in suitable random shapes that you search and salvage?
@@trippcailean9594 The artisan is the one still making the gems but the process of painfully spending much time and concentration on getting the cuts right is removed by using a programmed machine.
Seeing everything that goes in to polishing stones now make you appreciate how people did this freehand and with no special polishing compounds.
me too
When the title said cut I didn't quite expect grind.
@@manfredadams3252 Grinding is type of cutting.
@@manfredadams3252 you can't actually cut them, they are too fragile and could chip. so you have to slowly grind them down.
Yes but, if you go look at the royal jewels in London, most of the older crowns and jewelry pieces have gems without much luster due to inaccurate angles of grinding that reduces the light refraction.
Just imagine how stones in the Georgian and Victorian eras were cut! No matter how the technology advances however, the skill of the artisan is critical and the value of that will never be diminished.
That’s what I came to CZcams to search and then I found this video! Still so interesting
They still cut that way in India and Thailand.
Stones cut today are far better than Victorian stones. They are often poorly cut and polished compared to today's stunning gems.
@@rickrolls3786 Post and peg (jamb peg)? Yes, most of the native cut junk is still bashed out that way. I used to buy them cheap in bulk to use as preforms for my own faceting efforts.

The real beauty of the gemstone lies in the artisan's work and the way the light interacts with it.
Thanks 💎💎
A verdadeira beleza das pedras preciosas está na magnífica forma que foram criadas pela NATUREZA. O homem apenas a molda!
That's a big rock, even for amethyst, being that clean. Nice.
You got that right! thanks for watching!!! 💎💎💎💎
Sweet lord, I've never been into gems but that thing's so beautiful, my eyes are all glowy and stuff.
wow thank you so much 💎💎💎
j
You deserve one.
well the good news is it's only amethyst so it can be had for very cheap! maybe a couple hundered bucks at the most!
@@iWh15tl3 ppl
That was a really cool and thorough demonstration. A little more technical detail would be interesting - for example, how you set the parameters on the dop holder machine to get the right incremental change of angle for each facet, and how that has improved over time when people used to do it by eye.
The diagram of the cut at :50 appears to have the angular sets on the bottom half.
Lmao....that take a whole class to explain
I feel like gem cutting and polishing could be an ASMR video in itself.
I think this is my new favorite cut for gems. I never found princess cuts to be all that pretty and I'm so glad people are more open minded with different cuts for rings now! Your video was wonderful and a great example to show someone that, even with the machines to cut gems, it is still a human-operated process and time consuming.
I totally agree, Thanks for watching!!
One thing about CZcams is that it turns up videos like this where it might be something you didn't realise was interesting till you see it done to this level. Great to watch craftsmen turn out something like the Gem just seen.
👍👍 thanks for watching
I just can not imagine how precise their vision must be to achieve something like that. Marvelous….
I think I gained a liking for precious and semi-precious stones after both having had Geology classes in uni, as well as having collected Synthetic Opal D&D dice. To see everything that comes into play in order to give form and polish these gems is awe-inspiring.
This is beautiful artisanship.
Thanks👍💎💎💎
Algorythm gods brought me here
Glad you enjoyed it!

Just found him out while watching an opal channel.

I've always wondered how stones and gems were cut to create all the different facets. This was a great video! Thank you, beautiful work!
You are so welcome!
youtube.com/@cacadordepedraspreciosas6515
My exact sentiments.
Wow! I always loved jewelry and all types of gemstones and after watching this video, I now have a higher appreciation for them and respect for those who are involved in creating beautiful pieces each step of the way. Thank you for sharing, this was very interesting!
CZcams algorithm brought me here and cutting gems is absolutely therapeutic 👌
If the meets are cooperating 😅
My goodness, I had no idea that this was the process for cutting gemstones. It certainly takes a lot more care and patience than I imagined. And this was a very large gem. Cutting a very small gem must be painstaking.
Thank you! Cheers!
Beautiful work. It's amazing seeing something so precise coming out of something so rough. Do you think you could do a video on how the angles and dimensions of the facets are calculated?
Great suggestion!
@@stuartgems7593 Yes it would e great to watch a video on how you calculate the angles, and dimension. An while doing that video; if you could also tell us about the dials on the grinding arm, and what the equipment you're using does. Thank you for the upload; an looking forward to more informative videos. Best of luck to us all in 2021
@@stuartgems7593 That would be amazing! Another good one would be how you decide what cut/style to use for each gem and why. The last is something I've always wondered. Part of it is just the saze and shape of the rough, but there's always that other reason for using...say an Asscher over a square Emerald, or something like that. :)
@@stuartgems7593 we have lot of raw amethyst..
There is no calculating. The blue prints show where to turn the wheel and what degree ect…
What an extraordinary job you did. I now have a greater respect and appreciation for cut gems versus raw gems. 🙌🏼
👍😊💎
Wow, watching the process of faceting was truly mesmerizing! 😍 It's amazing how much skill and precision goes into cutting and shaping these beautiful gemstones. The intricate angles and facets really enhance the natural beauty of the amethyst. Thanks for sharing this incredible video with us! 👏
Thank you so much 😀
I do some rock tumbling... what I do is neat... what you do is amazing!
thank you so much!
I am studying gemology, maybe that's why the algorithm brought me here. Thank you for amazing work! And also thank you for helping me memorizing that cerium oxide is quartz polisher, I think I'll never forget XD
you are welcome thanks for watching and good luck with you studies
Stuart, thank you for taking the time to make this video. You have educated thousands of people to know how these gemstones are made. Your video was explains so much, is well organized and very educational. And your skill at making them is amazing!!
thanks so much it really mens a lot to me hearing such amazing feedback
Background song sounds like an even more acoustic Star Shopping from Peep
yea kinda
whats the name ?
@@robin-jx5jd star shopping - Lil peep
bcs it is
it is star shopping.
This guy is truly a master of his craft...
Thanks a lot!!😊👍💎💎
Well now I know how shiny rocks are made into even shinier rocks
thanks for watching!
What a process! Amazing video and that stone is gorgeous!!! Thank you for your time on this video.
Glad you enjoyed it!
Awesome to observe. I feel privileged to witness this stone cutting. These are secrets of a select group of initiates. And I think it's amazing to have this tutorial on the www. Thanks!
thanks so much 💎💎👍
This is one of the most mesmerizing and incredible things I've ever seen!
thanks so much!!
Randomly got interested in gem cutting type stuff and this video was the first time I got exactly what I was looking for. Great craftsmanship and editing skills! Super enjoyable to watch.
Awesome! Thank you!
Parabéns pelo trabalho!
💎💎💎
If I had to get a job this is definitely something I could do over and over. It's so beautiful and the process is so therapeutic.
Thanks!!💎
Amazing video and a beautiful stone.
I'm from Brazil and I do that but by handmade, I really needed a machine like that, the faceting is so perfect
Thank you very much! you can do it
I cannot imagine doing this by hand! A lost art some day....
I am in complete awe as to your skill, I hope you know that what you’re doing is extremely satisfying to watch
Thank you so much
As a layman, I was not expecting anything from this video, but at the end of the video my mouth was wide open, my gosh that light ! Then I subscribed and hit that bell icon.
Thanks👍💎💎💎
Gracias por mostrar de una manera tan clara y simple un proceso tan complejo y completo. No hay casi videos como éste por aquí. Gracias de nuevo
As a Portuguese person, I never knew we had our own gem cut, I have to say I absolutely love the end result! I clicked on the video for the beautiful gem and left having learnt a bunch of new things, thank you so much for sharing the process!
Glad you enjoyed it, Thanks for watching!!
of course you do, your country specializes in stolen minerals may as well know how to use them
@@drift163 Let me guess, you're Brazilian and all that you know about our history boils down to us going there and stealing your gold while ignoring everything that we have given back like culture, language, buildings and cityscapes, among many other foreign items. I also have to reinforce that Portugal was the FIRST country in the world to abolish slavery and it also swiftly ended colonialism, which is why Brazil, along with South American colonies that belonged to Spain, was made independent so early when compared to all other colonialized countries in the world. It has been 198 years since Brazil's independence, having happened in the 7th of September of 1822. To put it into perspective, there are ex-colonies that were only made independent around 1990, Portugal had given every single one of their colonies independence by 1975. It had only stayed that long due to a militar dictatorship happening at that same time (fascism in europe) because as soon as it was overtaken, the colonies were given their well deserved independence.
@@FXFGamer Esse aí foi vítima dos golpistas republicanos de 1889 que deturparam toda a história anterior do Brasil. O que não conseguiram destruir, substituíram, como foi o caso do dia do descobrimento (22 de abril) substituído pelo dia de Tiradentes (21 de abril) dito herói, que de herói não tem nada, apenas mais um revolucionário ambicioso que se tivesse sido bem sucedido teria, muito provavelmente, instaurado uma republiqueta aos moldes hispano-americanos. Mais recentemente a leitura marxísta dialética, terminou de desgraçar a coisa toda, tratando a história em ciclos econômicos e colocando a ideia de explorador versus explorado em toda a história do Brasil. Agora, eu sou partidário do Reino Unido Portugal, Brasil e Algarve, quiçá incluindo Angola como Estado autônomo e tornando-nos, portanto, um Império Tri-continental! Divagação minha, eu sei, mas seriamos uma das nações mais poderosas do mundo.
@@drift163 Ayo, relax, he is not the old Portuguese guys that stole gold, he just were born in Portugal. We still have gold, but not so much. Isn't his fold, im Brazilian, but of course if Portugal didn't have stole our gold we would be a rich country
Here all this time I thought cutting gemstones was a sweaty-palm white-nuckle affair with a hammer and chisel.
it is still often a white knuckle affair even with all the gadgets
well it aint RuneScape so I doubt it

This was very interesting to watch! You earned a new subscriber, and I'll definetly be checking out more of your videos!
I just love stuff like this. Gemstones, crystals, all of it. It's just so interesting.
thanks for the sub 💎💎💎💎💎
Love how you said "by gently removing it with the heat torch" because some of these gems, like the amethyst- are very heat sensitive^
Searched for this on a curious whim, it's amazing to me how each face on the gem was cut and polished by hand like that. The way the light reacts when reflected against each face was also mesmerising.
You also have a really relaxing voice, it made it a captivating and calming watch
Wow, thank you!💎💎💎
that's an amazing artform. i'm from brazil and rough gems like those are practically worthless, but in your hands it became at least a thousand times more valuable.
Thank you very much!
@@stuartgems7593 what would you say the value is once finished?
I'm curious to know final value as well.
@@warriormaiden9829 There are a few unique cutting styles seen today that are especially interesting, such as the 'Portuguese-cut'. Portuguese cut gemstones are faceted with an extra row of bezel facets, which result in more sparkle and color; this cutting style is typically seen only with large round or oval stones, minimizing waste. Princess cuts are popular because you don't need as big of a stone to do those, but they're also very DIFFICULT cuts to make.
@@MajimeTV Wonderful information, thank you for sharing! But I think you may have been replying to my other comment, the one asking about what goes into deciding what cut to use. XD
My dad was a successful gem businessman in the 60s through till the 90s and when I was a kid he used to show me all his gems. He passed away in 2001 before he could teach me about gems and this video reminded me of him. I do have some of his gems and I wear one of his Sri Lankan star sapphires as a ring.
thats lovely memory of your dad thanks for sharing 💎💎💎💎
Fascinating! I can’t believe how much of this is done by hand, but so delicate and precise!
Thats kinda funny. I was amazed at how effective the tool he was using is at eliminating human error.
Thank you very much!
As a stone setter I am often amazed by the work of the faceted end result. Thanks
Thanks for watching!!
Beautiful work .Your trade must have taken long hours , years to perfect.
My hats off to you .
Yes, thanks it has taking much time and a few disasters to get ware I am
but i always learn so much from from when tings do not go right it makes me a better cutter
@@stuartgems7593 Just out of curiosity how many hours of work is a piece like that? The work is self looks mind boggling...i wear glasses and am fairly poor sighted..
@@ciroweinstein8627 I did not keep track exactly but 20 hours approx over a few days with filming as this slows things down a bit
@@stuartgems7593 Wow!! Perfection takes time...Thank You for satisfying my curiosity
@@ciroweinstein8627 you are most welcome
I have never seen this done before from start to finish. Extremely skilled work, with beautiful results. Thank you for sharing your expertise. ❤

Thank you so much! 💎💎💎💎👍👍
"The pavilion of the gem is now complete and the gem is transferred to a new dock using a transfer jig"
I laughed thinking, "What if after all that fine craftsmanship, the 'transfer jig' is just him smacking it with a big hammer as hard as he can". lol
the bottom half of the facettes will be missaligned with the top ones if you dont use a jig bra
@@Tubemaster32 a size DD jig bra needed for some of those larger gems 😎
I'd love to buy 7 gems this size and cut, one for each colour of the rainbow.
Now that is a very nice idea!!! 💎💎💎💎💎💎💎
If/When I‘m rich I‘m going to exactly do that! Great Idea!
The Chaos Emeralds!
I taught you wanted to make The Infinity Gauntlet
Never heard of a Portuguese cut before that's pretty awesome.
Also your voice is literally made for ASMR
Never thought I would be genuinely star struck by a gemstone... I guess theres a first time for everything! Stellar work man, what an incredibly satisfying result!

Incredible stone, incredible work! Thanks for the video. For the first time in my life, I saw how jewelers work. I love stones, so beautiful!
Thank you very much!
Admirável sua arte!
this is incredible, the finished product looks so much more amazing than i could have pictured looking at what you started with. now I feel like all jewelry with gemstones in them should be so much more expensive, haha. I can't imagine how hard it would be to facet and polish something very tiny... amazing work!!!
Thank you! Cheers!
This is a forbidden gummy and i love it!

such a nice relaxing video . thank you. i’ve had a really rough day and this made it better.
I'm so glad! you feel better honestly i never dreamed my videos could have such an effect
I learned a lot from this video. It was randomly suggested to me, and I greatly enjoyed it. I never really thought of much work went into process (mostly haven't been interested in gems before) but this was very educational. You have a beautiful craft, and I appreciate the hard work you do. thank you so much for posting this.
Also you have a nice voice, and language in the video (by language I mean terminology), it was easy for me to understand what you were doing.
Glad you enjoyed it!
Hello
measure 1500 times, cut once! Great work!!
Cool, thanks!
So beautiful, now I want one!
thank you I have a website where you can buy my gems
@@stuartgems7593 It is a beautifully cut gem but I am not sure what I should do with a unset stone. Price is not bad.
This is absolutely amazing. The talent this gentleman has is above and beyond
thanks so much
Such an amazing piece of art. Love it!!
Thank you so much!
Very cool process that has raised some questions! 1) would be nice to know what impact to value this process has (if any). 2) You don't "cut off" asymmetrical pieces for small gems, instead you just grind it away?
How many hours of work does a piece like this take? Incredible video, thanks for sharing!
A lot i did not keep track but is was some ting like 30 hours to cut, film and edit
I have got a bit faster with the filming and editing tho
Normally whwen I watch a video showing skill, I think to myself "Well, with a few years of experience, I might be able to do something similar". Looking this video however, I'm like "Nope, never going to be able to do this."
Your skill is absolutely amazing!
You can do it! if you have enough patients 💎💎💎💎
@@stuartgems7593 thanks for your optimism ;)
I am new to faceting and found this to be hugely informative. Thanks so much!
Glad it was helpful!
from 90 to 30 carats that's kind of heart breaking :'l
yet it probably more than tripled in value :P
seems fine. The value of a gemstone is mostly inflated by the industry and also only worth what idiots believe they are worth.
You would be fired if you were a chemist with that kind of yield.
As much as I know, raw gems are sold cheap. That includes diamond. The cut made gems more expensive because it need skill, just like art.
@@zitronentee like how a lump of clay or block of marble is pretty cheap, but turning then into a vase or statue makes them valuable
Gorgeous cut and clean work this was amazing. I only hope this goes to decorate a beautiful piece of jewelry or a jewelry box. I have seen too many Portugese cut gems used for door handels and draw pulls and it makes me so sad, why use something so beautuful for something so tacky :(
Thank you so much!
with each step the gem gets even more beautiful, thank you for sharing your work ! Very lovely
Thank you so much!
Bravo! Excellent work and soothing relaxing! Keep up the great work! 💜👍
Thank you! 😊
There was something in the background music that was grabbing my attention but I couldn't tell what it was... Until it hit me. Star shopping - Lil Peep. Rest in piece bro
I was looking for that comment, I thought exactly the same cheers.
I KNEW IT
the song s called Silky Smooth
Thank you for your video, I never knew how this done. It just seems to me when your hand polishing it that you might wear some of the pattern. is the stone that that strong? Is this the way it was done in the old days with the electrical motors?
Thanks for watching! the proses is similar to the old days tho the machines have changed a lot
and yes it is posable to ware away the pattern when polishing care and carful planning is needed to avoid that
Sheeesh, the patience and accuracy needed to cut them into shapes.. 😶, great job 💯👍
Thanks 👍
Now transfer this degree of precision grinding to knife makery for a his-dark-materials style blade
Now thats an idea
@@stuartgems7593 I wonder if the grinding disc would be affected by the metal. I'd assume that it'd be just fine, given the hardness of Amethyst? i'd love to see how sharp a mirror polished blade edge would be
@@jonathonhebert7042 about $5000 for the machine and you could try. Now if you want 19 degrees in the blade angle, you'll get 19 degrees. 🙃.

Now I know why they say "Gem Of A Person"
💎💎💎
A question- what happens to the dust created by shaping any type of gemstone?
Most is carried off in the water coolant/lubricant. Any landing on the stone, lap etc are carefully wiped off between grit changes.
In our country everyone would say that your hands are made of gold 💜
Great video, love it❤

Fascinating! As a rock collector I love amethyst but to see it cut that way is pretty amazing...👏
Glad you enjoyed it!
Thanks for watching if you have any questions leave a comment below and Ill answer them there.
Your work is beautiful! I have a young teen fascinated with all things geology...any advice on how to learn the art of gem cutting? Is it apprenticeship based or are there degree or certificate programs for this sort of thing?
@@aminad6903 Hi, there are places where you can take a course in gem cutting and lapidary clubs is also a popular place to learn it depends on where you live if it is available, not many apprenticeships on offer Gemmology is the study of the identification of gemstones and you can do a degree in that lookup Gem-A and GIA, and rockhounding is the hobby of looking for and collecting gems and minerals
@@stuartgems7593 thanks!🙂
@@stuartgems7593 Hi! Wonderful work. I was wondering with the gem going from 90 ct to 30 ct, is anything done to try to save the sanded off material? Or how do you best minimize that loss in the planning process?

That is so gorgeous! To think once people used to do this free-hand, how is beyond me.
yes they did but the designs wore much simpler
@@stuartgems7593 Nor did they do them well or at the proper facet angles.

Your Portuguese cut is much more appealing than a traditional Portuguese which can look bloated below the table. You did well and it looks like the labor to create that finished stone is way underrated. Cheers!
First time I’ve been watched this. It’s amazing! I wish you a good health and to be always creative! Be happy!
thank yo so much
Damn from 90 carats to 30....
my next video will explain why this happens
Wow that’s a lot of waste. I mean incredible job, but I never realised quite how much of a gem is lost when you cut it. Literally a third of the original size?.!!!?!!???!!?
that's why these types of cuts are so valued because they maximize the amount of gemstone cut, unless you're doing a literal orb
Much more :( it went from 91 carat to 30
The value only comes out from the cut, otherwise it's simply a stone. A lot of thought goes into which design is best for the individual gem. It may seem like a loss, but without it we could never witness that bling bling
That's not unusual, to create a beautiful design. It's a lovely gem.
There is no other way to get a completely symmetrical stone.
That was such a satisfying video. Beautiful piece, wonderful to watch. Thank you for sharing that with us.
Thank you very much!
Great video. Thats amazing how much work goes into such a beautiful stone.
