I Cut a Raw 10 Carat Montana Sapphire Into a Beautiful Gemstone

[@jansalomin]

I'm surprised that channels like these that show the whole process and are really down to earth aren't more popular.

I never thought I would spend my Saturday night watching videos on gem stone cutting. Well done! Please keep them coming.

[@karthikeyanumerologyaravin308]

Stone like a Aquamarine

[@ron.v]

A gorgeous cut that was even prettier after heat treating. Thanks.

[@zelousfoxtrot3390]

Spent the whole video wondering about heat treatment... That is beautiful, and looks great. You did a wonderful job, and I bet they are very happy.

[@LakeOuachita]

Wow! Gorgeous stone, awesome cutting...and the heat treatment made it pop!

[@ArtemysNyx]

wow the final ring looks amazing. def the right choice to heat treat to get that blue color.

[@israelp6068]

Amazing! Never knew these tools existed to show you how the gem will look before you cut it and how you're able to adjust it to get the perfect cut desired. My dream job is to work in the gem/jewelry business one day. Thank you for sharing this wonderful knowledge 🙏🏽

[@MattsCornerofGemCutting]

I really liked seeing this stone go into a beautiful ring! I know a lot of people are going to ask about the value of the sapphire. Value on stones like this depend a lot on who it selling it and I'm not an actual appraiser, but I'd estimate the value of it cut and after heating to be somewhere between $1,000-$2000/carat. Before heating, maybe $800/carat. The piece is 4.62 carats.

[@JulyEmerald]

You do some really good work and just got yourself a new subscriber🎉

[@OrlanOcares-j3w]

Sir I have more rough diamonds

[@fwiffo]

I just found a >9 carat stone in some Eldorado Bar mail-order gravel. It's a pretty nice sky blue color, but has some silk and will need heat treatment. Also, it's got some pretty big fractures down the middle. At what point do cracks make a stone impractical to facet? It's big, and has a nice crystal shape, so I'm confident it would be an impressive stone if it's possible to cut it. But if it's probably just going to fall apart, I'll just keep it as a mineral specimen. (I realize you can't evaluate a stone without seeing it, but I can send pictures if you're curious).

[@andnowi]

I prefer unheated. Is this unusual?

[@iolightning]

Heat treating is such a gamble. Yes: color is richer, clarity generally better, and I'm betting the owner is pretty happy with the result. But... as a collector, I love brighter "sleepy" or silky sapphires, and an unheated Montana over 4 ct is incredibly rare. Well, even a heated one is incredibly rare! Thank you for sharing your process for weight retention while maximizing beauty. It really shows how an expert gem cutter uses science, art, and experience all together.

[@awesomeFrost]

beautiful cut. The heat treatment really brought out the dark blues of that sapphire. the cloudiness might have worked out in their favor if they enjoy a deep navy blue

[@stevenbriggs784]

Im so glad you're still uploading and cutting! so many of my favourite cutters have passed or stopped uploading because of low view count but you're out here smashing it! thankyou!!!! (get a patrion PLEASE so we can support you)

[@DaughterOfDrakes]

I'm not an expert or anything of course but I gotta say, I kinda liked how it looked better before the heat treatment. That super gentle blue with the slight cloudiness kinda reminded me of a sky with some wispy clouds or something.

[@KethrieDyrdahl]

I can’t wait to see you cut the pink sapphire you found!! I’m also curious about that big, long one you said will make an incredible emerald cut!

[@hugotorrado3948]

Very difficult trade, you master the cutting of precious stones, thank for the video. Best Regards.

[@sproutingresilience4787]

Yay more Matt’s corner! I watched all of your videos when i first found your channel and was disappointment when there wasn’t more to watch!

[@katharinatrub1338]

Math, what a Beauty of a Gem you pulled out of your Magic Hat! I am in Awe! Yes, I love the way the Table became kind of a marquise Shape (sorry for my vocabulary). I am fascinated, hypnotized by watching you cutting Stones! Greetings from snowy Quebec.

[@fwiffo]

I'm having a lot of fun searching through Montana sapphire gravel. I don't cut gems myself, so I just (today) sent a parcel back to Gem Mountain to have them cut (and some heat treated as well). It'll be a bit of a wait, but I'm excited to see how they come back. I loved the natural color of this one, but it was pretty cloudy, so I think I would have gone with heat treatment too.

[@Gprince2121]

Dude, I love your channel, please Keep making videos. I’d really like to see more on the process of you designing the facets on the computer. Great work 👍🏻

[@denisecaster1251]

❤It actually turned out very pretty after the heat treatment! What a nice surprise! Very nice cut by the way!❤

[@interestings7866]

Yo the cad and 3d work is awesome! So cool to see that process before you start cutting

[@sandrapicton6349]

Gasp! What a beautiful stone you created, it looks gorgeous in its setting.

[@pamelah6431]

God created the stone. He just cut it. :)

[@cossack814]

8:14 I actually really like the cloudiness when looking at the bottom of the gem

[@iiniijewelry]

Nice work! I live in Montana and am good friends with a lot of the local sapphire mines. Good people.

[@jessie-yz5vz]

this is SO CRAZY. just a curious mind who wanted to know how stuff is made AND THIS IS SUPER INTERESTING i had no clue how mathematical and technical of skills you needed for something like this. Very talented and skilled!!

[@kdkrueger112]

Really enjoy these videos. Beautiful work

[@nancyhainline2517]

Wow. Have gone thru nuckets and buckets from Spokane Bar Mine. The sapphires I've retrieved have been small and fractured. Congratulations on a lovely find.

[@wigtea5620]

That was the best stone I’ve ever seen

[@sinch4044]

Oh it's so beautiful after the heat treatment but I prefer it much more before I think. It's such a gorgeous cloudy mysterious green

[@christinewebb1485]

When I 1st moved to this area a girl I worked with had a pink stone set in white gold. I asked what stone it was & she said a Pink Sapphires from her father's mine. It was amazing to visit with her dad when we went there.

[@ChrisEbbrsen]

Thank you! Have been wanting a gents white sapphire ring for approx. Three years. According to a book on mysticism the white sapphire us supposed to render special powers to piceans. Hence have been hoping to design a ring and find a nice big ten carrot white sapphire for myself. Your vidio has given me hope that in Montana I might find such a stone. Thank you for your beautiful vidio!

[@Freerunx3]

I thought the gem looked a little weird but the ring designer really brought it all together and made it look awesome.

[@BenGrigsby]

[@jenniferbutcher8393]

[@Nervii_Champion]

I'm fairly certain that was an extremely rare Star Montana Sapphire. It looked like a big cloud of Titanium Oxide in the middle, and then another layer closer to the outside of the stone. Could have been more than enough to get a 6 ray star.

[@MattsCornerofGemCutting]

Thank You!

[@EvXXL97]

When they say “cutting gems” I genuinely thought they cut them, like carving. Grinding it makes so much more sense though XD

[@kikiseesworld]

thanks for sharing your process! what lap are you using for the 600 grit? and what cutting laps do you suggest?

[@adrianvaldez9102]

How did it turn blue in the end? Because of the heat treatment?

[@MattsCornerofGemCutting]

Yes, the client sent it in for heat treatment after I sent it back. Heat treatment is primarily used to enhance color and clarity.

[@nikkan3810]

I like the soft spherical warp it does with this low clarity. Would actually prefer this to a clearer stone, feels more natural.

[@John-uz4et]

This might sound dumb but do gem cutters get inspiration from origami? I just noticed from your videos how similar facets are to the symmetry of origami folds

[@laurenholloway4430]

How much u charge to cut sum stone i have.

[@centurione6489]

I didn't know that faceting gemstones was sooo easy. 🤣

[@Saywhatohno]

where can i send the stone to get heat treated?

[@yozzgun]

It seems fascinating! Iwant to cut my own gems too. Where can i learn this skill?

[@acetydesfrancisco-hm9up]

Esse corte é fantasia? E safira não poli igual rubi, disco de cobre?

[@davidkerr4137]

So I'm aware there are different colours of sapphire but do all blue sapphires need to be heat treated to get the classic sapphire blue look?

[@drake2421]

Hey Matt ! That's an amazing work you do ! Congrats! I wanna ask how you learn stone facetting, because I wanna try and mabye learn for doing it as a professionals. I begin to watch a lot of videos about facetting and I begin to understand how it works but finding a facetting machine is pretty expensive (I'm in France btw).... What's your advice and tips for begining as the hobbyist I am😀

[@jamesmudd2227]

Wow stone looks amazing, after you cut it and it was heat treated! What is the approximate value of the sapphire after being completely finished Matt ?

[@roseanneatkinson3022]

Do you cut stones for other people? I love your videos. I have a 1.3 ct of Tourmaline. Is it too small to cut?

[@gemmaology781]

Unpopular opinion but I love the cloudy greenish/grayish/blue of the montana sapphires 😍

[@jennyblew]

It's my niece's engagement ring!

[@scottpolo688]

Beautiful stone especially after heating! I was under the impression that if you heat a sapphire after its cut you have to repolish the facets …… does not appear to be the case with this stone?

[@Mike.The.Jeweler]

most heat treaters will have a lap on site and they'll re-polish as a fee with the treating, much cheaper and easier to re-polish a stone rather than fully cut one from rough.

[@JiangJiaChun]

l have one like this. what is this stone. name. how much price it can sale?

[@marcushillen8680]

I'm a new subscriber and I love the content even though I don't know much about it. On the closeups of the stone where you're holding it, your nails tend to look beat up. idk if it's due to biting your nails(I do the same when I watch soccer) or if they get damaged from what you do for a living, but honestly with all the grits and shining and polishing and every other similarity to stone-cutting, nail care would probably be a cool side hobby for a guy who works on gems to pick up. Sorry if that's offensive, just something I noticed.

[@danno5645]

I’m curious what you charge to facet a gem of the size. I’m interested in getting some gems faceted in the future.

[@Dogfoodsoup79]

Very cool to see the process. How long, approximately, does it take you to do a gem?

[@huangxiajing9986]

Beautiful

[@annhans3535]

How it looked so blue at the end?

[@theelementair96]

[@amandagawith4822]

How many different kinds of sapphires are there ?

[@richarddavies7419]

If you mean color, sapphire is every color but red, which is known as "ruby" even though all of these are the mineral corundum.

[@TheFretman2]

Sleepy stone. I’m surprised the heat treating didn’t mess up your polish.

[@mrpakuntay]

hi sir, i wanna asking if you had attended any school of gems faceting? or you learn it by your self. thank you.

[@scottlidstone1902]

Forgive a possibly stupid question, why is called cutting? It looks more like grinding? 😅

[@robertrobbins5759]

Would you be interested in cutting another big quartz crystal like the one you did in the video

[@morgan9204-n8v]

very nice

[@Bikerack2]

I'm just curious to know what the gem is worth in dollars.

[@54321Judith]

Why did the color change so dramatically after being heat treated?😲

[@Wearestarstuff84]

The cloudiness is caused by a mineral called rutile. The heating process reaches a temperature that is too low to melt sapphire, but high enough to melt the rutile. Once the rutile reaches the right temp, it diffuses into the sapphires crystal structure and produces the brilliant blue color.

[@Andrew-uo6to]

How does one go about hiring you? I have a cuprite crystal and want to find someone to cut it for me.

[@cliveb9771]

Very interesting !

[@Leafbinder]

Are these really Sapphires or just colored quarts called Montana Sapphires?

[@MattsCornerofGemCutting]

They are really sapphires.
