Is there anyone else out there who can appreciate the absolute beauty of the natural cut Tanzanite? They do look spectacular when coloured but I really wish that more natural stones were made available. They can come in the most incredible colours. Is it just me or do others see this natural beauty as well?
@Ian S Thank you, I appreciate the support!💖
Steve, I started faceting regularly about a year ago. My "training/lessons" have come almost completely from your videos. I've watched them all and some as many as five times.
I not only listen carefully to every word you say, but have picked up many of your methods by just watching you cut. My wife, who has been faceting much longer than I will see me making a small move on the wheel and mention, "You do that exactly like Moriarty." To which I reply, "Exactly. He's my guru."
Thanks for this great video and the many others you've produced.

Hi, I’m in Vegas too- I bet you’re as sad as I am about the gemshow- this coronavirus is the pits- although you’re probably are getting a lot of cutting done ☺️ stay healthy ❤️
whoever disliked this video probably did it out of spite and jealousy. once again, I learned a lot today.
Right
I've been looking to do something like this as a hobby but now I see how much work and knowledge you'd need to cut a good diamond. it's the math that gets me😆
I was NOT expecting that color!! Magnificent!
So intressant to hear you talk about the rough gem and the problems you run into with it. You are a master and I enjoyed watching you work and the finished gems are amazing love the colors and shapes of them! Thank you for sharing your work with us here on TH-cam! I wish I could be there with you just watching your work...👋😊💎👍❤
A few weeks ago I didn't know anything about gem cutting. After coming across these videos now I have a deep desire to get into it. Thanks so much for uploading.

Neat how the heat changes the color. I like both.
Wow. I cant figure out which I like better, I almost like the color of the unheated tanzanite better than the latter but both are STUNNING. NICE WORK I LOVE WATCHING YOU DO THIS. AMAZING SIR.
Thanks Melissa
Stunning stones, thanks for sharing your process!
I’m hooked! Love watching you work.
Great video! Thanks for taking the time to show us.
I wish you guys did more videos like this. I love the information.
Sir, You have Nerves of STEEL !
Another great vid, Steve. You are just about the only person on TH-cam making such videos. Much appreciated.
Thanks for following our work JLards! We appreciate all your feedback, too. :D
@@Moregems Hello, I am a colored stone cutter, [no diamonds] and I enjoy your vtdeos immensely . Actually, I would like to talk to you sometime. I have a couple of questions that maybe you can help me with. BTW, your videos are well done, lighting, etc. Thanks!
I'm not a jeweler and have never cut a stone but I love stones and was just wondering why not leave them the natural color? I'm aware tanzanite usually has a blue hue but the brownish bluish color of the natural stone was beautiful to me. Just my thoughts. Great video though.
Hey Scott, thanks for watching! It's not easy to sell a natural unheated diesel color tanzanite. Not many people would know what it is or want to pay the price of tanzanite as a diesel colored stone. There is a much larger market for heated tanzanite, which is the color most are looking for when shopping for a tanzanite.
It's all about the money!
I liked the brown colour too.
@@joedeardo2855 sad but true its called commercialism
Nice brilliant work, thanks Steve for ur video.
Steve, thanks for such a beautiful work.
Funke Omole
Thanks for watching
great job sir.. hats off
Fantastic work!
Beautifully done.
Old way but gold way. Salute for him. He is a gifted gem cutter.
you are a "GEM" of a person steve….. learnt a lot....
That is an incredible piece of rough. Thanks for the videos!
Thanks for watching! Let us know if you have any questions.
There is a really good way to mix epoxy if you have dremel you might like. You can use a glass slab as the base for mixing. You take a ball mill and put it into the dremel backwards so the smooth shaft is sticking out. Just place the smooth shaft into the epoxy and turn it on and move it through the epoxy. The spinning shaft mixes the epoxy really well. If you have the shaft touching the glass slab the whole time, it will mix without any bubbles in the epoxy.
Your such a gifted man. I'm new to faceting. So thank you for spending time to make such videos, as I'm learning so much.
Thank you for the kind comment! Please feel free to subscribe and let us know if you have any questions!
Wow
Great teacher 👍 God bless you.
I loved both colours great work
Amazing work magnificent !! Congratulations!
Thanks for watching!
Thank you so much, for sharing your knowledge and experience. In my eyes, you are somebody that I can look up to and respect.
Carl Pullen Thanks I appreciate your comments.
Inspiring me to become a jeweler with every video thank you
Thanks for watching, let us know if you have any questions.
One way to remove epoxy is to put a round toothpick in a dremel. The spinning toothpick heats up the epoxy from friction and causes it to overcure, powder and come off. The heat is localized to the surface where there is friction.
Many thanks! another great & instructive video! Whenever I'll visit the Midwest-USA again, I'll make sure visiting Crown Point. Thanks!
You're welcome! That would be great, please feel free to stop in and say hello!
Thank you Sir, keep on going with this content
Wow! Absolutely Fabulous! I look 👀 in & cruise through it into a magnificent cosmos! That’s Divine! Your work is divine. Thanks for sharing. ❤
😳WOW, awesome job ❣️ The color's are FABULOUS 🤩. And the clarity is MAGNIFICENT ❣️❣️❣️
Beautiful stones, thank you for the video
Amazing !!
Thank you for sharing your talents. I sure wish that I could be your apprentice, Cory
Cory Streat Thanks Cory
Thank you for sharing your FASCINATING process. Seeing a master at work is always such an honor.
I’m probably a monster for saying this, but I found the original colors more appealing.
Great job Steve, in Australia we call that making silk purses out of sows ears. The colour change is spectacular to say the least. I enjoy watching you go about your work mate you make it look easy .
Thanks for watching!
Great work!!!! wonderful, cheers!
Love this. Thank you.
Glad to hear you enjoyed it!
Awesome work.
Thanks Valken!
Very interesting ,cant wait to do things like that. You re an inspiration
francois robillard Thanks
Honestly ,I personally like it unseated , I love the rainbows, on saying that they are two beautiful stones you have there.
Wow! your hired...thanks for sharing your incredible talent with us,beautiful stones.
Thanks Angela
I ❤this show! Mr. MoreGems you are a fantastic teacher! I learned so much about the process of cutting an oddball stone-but oh what beauties they turned out to be! Are they still for sale? I want that big purple monster…perfection! Thank you for your calm, patient manners. You are wonderful!
Thanks so much for making these tutorials. Would you tell me what specific lapidary machine you are working with?
Very good diamond polishing robots for round rough goods. We use to have some of them in Puerto Rico in the late 90s.
Great videos! I have been looking for a heater for jewels. Most are Chineese. Which do you reccomend?
Esplêndido, estou começando a trabalhar na arte do faceting, quero saber mais sobre o uso desses filtros.
VERY INTRESTING. THANK"S A LOT.
All is good. Two very beautiful stones. W O W !
Magnífico trabalho Steve. Congratulation, parabéns!
great job man that was an engineering of gemstones

Thanks for watching.
These videos are so nice to watch! Thank you for uploading, but i keep wonder what stone you have in your ring :)? Is it à zirkon? Or a paraiba perhaps?
Thank you again for all these videos, Cheers from Sweden.
You're welcome! Thanks for watching and let us know if you have any more questions! As for Steve's rings featured in our videos.... The one he is wearing in this particular video is an Aquamarine, and you'll also see him wearing a high dome cabbed Ethiopian Opal.
Must have been aqua. First ring I ever made circa 1990. Cut the stone and cut the wax model. It’s the only ring I have owned that has not gone up for sale. I have had nicer but it’s sentimental.
very profesional this Man,,,,,,,,,,nice job
Sir i salute ur craftmanship blessings
Thank you for your upload, I Novices have learned a lot, the last white powder for heating? What is it?
Amazing.
honestly I think I prefer the natural colors of the stones before heating. there's something so beautiful about the mix of blue, green, yellow, brown, and what looked like a tiny tint of pinkish purple. wonderful job cutting the stones though! regardless of the color they look amazing!
Here’s a new natural. www.moregems.com/products/tanzanite-gemstone-1
Beautiful!!!💙
The finished stones looked amazing to me. Great job! I bought some used lapidary equipment a couple years ago but never tried using anything but the small rock saw and didn't even use that for it's intended purpose. But since I have some raw sapphires and sunstones I got from Oregon and Montana over the last few years I thought I might try my hand at doing some faceting etc. I live in NC and see there is a class in western NC to help me get started. Any good tips for a total novice you could share? Thanks, TW.
My full series on how to cut gemstones should get you up and running
I really love to watch ...indeed patience is virtue
There are a lot of films about stone cutting on the Internet. There are only a few films where the cutter feels the difference between a cut and a not bad cut. 👍good luck
I've found that when you are transferring a stone and have to use heat I take a strip of cloth, dampen it, wrap it around the stone near where is going to be heated. It keeps the stone cool and keeps from breaking the stone when trying to get it to release.
Grabbed a 1,000 thing from the oven with his bare hands. What a guy.
Thank you for the video it's very informative I have learned a lot from you one question though why wouldn't you heat up the stone while it's rough and heated up after it's cut instead, maybe you afraid the fracture would go further up and damage Stone ?
Tai Te yes, we didn’t heat this crystal before we cut it because there were too many risky inclusions that could cause the stone to (like you said) fracture and damage the gem. It is much safer to heat a clean gem, although as you saw, there was still one inclusion in the larger cut gem that we were worried about when heating in the oven. That is why we heated it much slower than we would usually, to try to lower the risk of damage. If the rough was clean, then yes, definitely you can heat before cutting. There are also some instances where you have to heat it with an inclusion in (due to being unable to cut it out), so sometimes it is better to just heat it so you’re not wasting your time cutting, then you heat it and it cracks. It really just depends on the circumstance, but for this crystal, we were going to be cutting most of the risky material out, so decided to heat it after.
Wish I could work with you guys.
Hi, Thanks, I will view more of your series. Just one more question. I see you do some of your own heat treating and I'm wondering what brand/model oven and would it be also suitable for other stones such as sapphires? I liked that it was small and programmable.
This oven goes up to 2000 Fahrenheit so it has limited use with sapphire. www.gesswein.com/p-1622-ney-vulcan-furnaces.aspx.
After heating the tanzanite looks very beautiful, I want to ask, when the stone is heated do you use a flux of Calcium Carbonate or Borax or what material? thank you 🙏
I shuddered when the stone started to chatter while polishing the table. That can damage your facet meets or even rip the stone from the dop.
Get yourself a 45 degree adapter (or have one machined to fit your AT. That way you won't have the chattering risk. I bought my AT used and the previous owner had had a custom adapter made for him.
Also, if the stone will tolerate it, you can soak the stone and dop in acetone to soften the epoxy and make it easier to remove.
I also have a question. Is there any particular reason why Steve uses epoxy rather than dopping wax?
This video for thanks.Succesfully!
Awww thank you for sharing your talent! I have a huge citrine from Salon in WW2, it’s cut lovely like this one, not really sure what to do with it?
Thanks again, form Canada 🌹🌼🌺🌸🍁
both are beautiful stones after the heat treatment. I liked them before honestly, almost an imperial topaz color with underlying flashes of other colors. I really am a fan of the blue/green tanzanite, is that heat treated also to get that color?
This is heaven on earth.
Really nice video, very educational, well done! I do have a question, you heat treated the tanzanite at 1000 degrees but don’t specify if was Celsius or Fahrenheit? I’m a member of the Livingston Gems and mineral society in Hartland Michigan.... Thanks
Hi pimardd! Thanks for watching, we heat it to 1000 degrees Fahrenheit. Here is another video showing this process: th-cam.com/video/FrxvHi3Rtcs/w-d-xo.htmlm9s
I new it I usually heated at 535 to 540 centígrados ( Celsius.) thanks again for sharing knowledge and keep the beautiful awesome job.
I have watched some of your videos and recently been practicing cutring myself. Why are impact diamonds not known about and on the market? They are incredibly beautiful, there is a variety of them as big as the entire group of silicates and the amount of them is incredible. I especially like the impact diamond petrified cactus pieces. In one of your videos you have some diamonds that look like they are exactly that, petrified cactus impact diamond.
The powder is casting investment which withstands the high temperatures.
Nice!!!
Pretty both
I've had a hankering for gem cutting lately and I'm thinking of getting into the hobby. I have one question. Where is the best place to buy loose gem stones?
If you're looking for rough, you can look for local gem and mineral shows or visit the largest shows (if you're in the US) in Denver or Tucson.
Great , I m interested in hearing purplish corundom ,and elimination of bluish hue ,and turning the stone in red color.sir if u can give me some tips on thermochemical process.regards. Shaukat zaman
Holy shit so pretty after heating that's amazing
A great video for sure. I do have to ask if you considered cutting the larger pieces off in tact? I use my band saw to trim away inclusions on stones this large. It preserves more of the gem than simply grinding away so much material. Just a thought I wanted to share.
Tell us about the machine you are using please. Very interesting video's. Keep them coming.
Chuck Holder new cutting videos coming on my new machine the ultra tec V5
🙏like always a good job
And , how do you cut and polish very tiny/small stones.... ???
Arnaldo Vinagre I don’t I leave it to the cutters in India
Very informative :)
thank you for making the videos... I enjoy learning the process but could you wear a mic, your soft spoken and I can't turn up the volume enough to hear some of what you're saying
great video.. question would be how you come up with the design for a particular rough you intend to cut? Is there a specific rule of thumb?
We look for the best yield that the rough will give us and cut that shape.
Gosto muito do seu trabalho meu amigo receba um abraço de seu amigo BRASILEIRO
Did you already have a buyer or is this commission work? Enjoyed the vid and you are a great teacher.
The1122007 cut for our stock. Both sold quickly
how much does heat use and how long does it take? Thanks very much, My dear Sir.
Congrats you have excellent work.
Where can I buy the discs you have processed?❤❤❤
Kingsley North in Michigan
@@Moregems
I do not understand what you are saying
can you write in english please..
@@Moregems
I asked you about the discs you processed, can you help me?
I'm curious as to why you would not want to get it to hot when applying/removing the dop, knowing you need to heat treat it later. Would it not be better to have it shatter earlier on in the process, rather than after you've put in all the effort of faceting it? Or is less likely to shatter during heat treating due to the more even heat distribution?
Zac Lester yes slow steady heating is less of a problem.
@@Moregems That makes sense. Thank you, and great video!
Muito bom legal
What’s the soundtrack? This music is fantastic
Thought color treatments were considered a bad thing in many stones. Beautiful result regardless.
True Sighted Without heating as a color enhancement we would have nothing to sell. Up to 90 percent of ruby, sapphire, emerald to name a few are enhanced in some method. Heating is permanent and generally accepted.
@@Moregems was not aware of that. Just going off the info I had heard. That color treatment was frowned on. No worry though. Turned out beautifully, and so long as the crystal matrix of the stone is stable and the color permanent..more power to you. I'm still learning every day.
You have the nicest, neatest nails of any jeweler on youtube.
Haha, well thank you!
