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?

[@krisushi1]

@Ian S Thank you, I appreciate the support!💖

[@Fearnoopal]

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😆

[@johncrumpley8702]

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. John in Las Vegas

[@myronww]

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.

[@Moregems]

Thanks for watching!

[@myronww]

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.

[@carlpullen4308]

Very good diamond polishing robots for round rough goods. We use to have some of them in Puerto Rico in the late 90s.

[@scott27288]

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.

[@Moregems]

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.

Funke Omole Thanks for watching

[@Draukagrissah]

I know you were worried about it as a flaw but I think the depth on the stone to increase the color was the absolutely correct choice. Depending on the angle it can be the color of butterfly pea blossom tea or deep ultramarine!

[@pezzottaitemeh8616]

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!

[@user-ut7sz1pz4b]

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.

[@TrueSighted]

Thought color treatments were considered a bad thing in many stones. Beautiful result regardless.

[@Moregems]

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.

[@TrueSighted]

@@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.

[@shriyaI]

Holy shit so pretty after heating that's amazing

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.

[@amostecumseh6931]

[@terrywolford7880]

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.

[@buggsy5]

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?

I like your videos but please get one of the microphones you put on your shirt because it's very hard to hear you

[@tjinc002]

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 ?

[@Moregems]

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.

[@augustochendi429]

Pretty both

[@ThatDashingDasher]

Thanks so much for making these tutorials. Would you tell me what specific lapidary machine you are working with?

[@geebrewer8186]

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?

[@alejandromendez1305]

[@instagem2693]

Very informative :)

[@Schtroumpsolis]

CAN YOU TALK ABOUT THE TIME IT TAKES TO CUT A STONE .PLEASE, THANK YOU /

[@Moregems]

3 to 8 hours would be average. Size and inclusions are the biggest variable. Big ones and included stones take longer

[@CB-68-westcreations]

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.

[@jameeljalal5484]

What is name of stone sir?

[@user-xm3lo1vk2u]

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 🙏

[@terrywolford7880]

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.

[@Moregems]

This oven goes up to 2000 Fahrenheit so it has limited use with sapphire. www.gesswein.com/p-1622-ney-vulcan-furnaces.aspx.
