How are gemstones cut faceting a 30ct Brazilian amethyst 

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.

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.

That’s what I came to RU-vid 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.

You got that right! thanks for watching!!! 💎💎💎💎

Thanks 💎💎

A verdadeira beleza das pedras preciosas está na magnífica forma que foram criadas pela NATUREZA. O homem apenas a molda!

👍👍 thanks for watching

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

Thanks👍💎💎💎

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 totally agree, Thanks for watching!!

You are so welcome!

My exact sentiments.

If the meets are cooperating 😅

bcs it is

it is star shopping.

it is still often a white knuckle affair even with all the gadgets

well it aint RuneScape so I doubt it

@@JMRabil675 "You forgot to calibrate the machine. You grind the uncut amethyst into dust."

@@JMRabil675 i got 99 crafting cutting all gems in runescape lol my hacked account was called Collect Gems had a 5b+ gem collection

you are welcome thanks for watching and good luck with you studies

👍😊💎

Thank you so much 😀

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…

Thanks a lot!!😊👍💎💎

I cannot imagine doing this by hand! A lost art some day....

thank you so much!

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

thank you so much!!

Thank you so much! 💎💎💎💎👍👍

Thats kinda funny. I was amazed at how effective the tool he was using is at eliminating human error.

Thank you very much!

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 😎

Thanks for watching!!

Thanks!!💎

Wow, thank you!

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

Thank you! Cheers!

I'm so glad! you feel better honestly i never dreamed my videos could have such an effect

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

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?

@@anonymous6687 noting is done with the dust, yes the best way minimize that loss in the planning process I will go into this in more detail in upcoming video

Thank you very much!

thats lovely memory of your dad thanks for sharing 💎💎💎💎

Thanks for watching

Now that is a very nice idea!!! 💎💎💎💎💎💎💎

If/When I‘m rich I‘m going to exactly do that! Great Idea!

Love the song

the song s called Silky Smooth

Gus

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.

Muito bonito mesmo pedra brasileira bem trabalhada com máquina apropriada e bom profissional acaba valendo muito lá fora.

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

Thank you so much!

You’re welcome 😊

✨

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

I was looking for that comment, I thought exactly the same cheers.

I KNEW IT

the song s called Silky Smooth

You are so welcome

it dos look yummy💎💎💎

it tastes like grappe

It looks like candy. I wanna eat it

@@aricre8886 lol

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

Cool, thanks!

💎💎💎

thanks so much

Most is carried off in the water coolant/lubricant. Any landing on the stone, lap etc are carefully wiped off between grit changes.

Thank you so much 😀

Thank you very much!

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. 🙃.

i was looking for this comment! rip indeed
