Gem Cutting Tutorial: Rainbow LC Sapphire Ring
ฝัง
- เผยแพร่เมื่อ 3 พ.ย. 2023
- In our last video, Mike was testing the “Rainbow” design by Jeff Graham on some Mexican Fire Opal. The reason for this test, was because Bopie had requested a lab created sapphire in this design, intended for a ring setting that she happened to have on hand. Watch as award-winning gem cutter, Michael Sackos, once again, facets this beautiful oval design, but this time on some lab created sapphire. Watch until the end to see the final product of the completed sapphire ring.

Lovely work Mike...This synth sapphire really looks nice. I look forward to you discussing more about this material.
Thanks Cliff. I am working on a project with a big hunk of this lab created Sapphire. I'll explain more about it at that time.
Once again, beautiful work. Thanks - you make it look easy! It’s really nice to see the stone set in the final piece. Your wife does beautiful work and I would love to see more finished pieces on occasion
Thank you. We will try to show the finished jewelry more often. Great suggestion.
I love synthetic gemstones. It's just such a cost-effective way to get large gemstones for various settings where you want to show off the splendor of the stone and the intricacy of the cut in a way that a smaller natural stone of the same price might not be suitable. Plus, with synthetic stones, you don't really have to worry about the ethics of how they're sourced nearly as much as with natural, mined stones. That looks like a lovely color based on the slab and the translucency is spectacular for such a thick slab of corundum.
Wow, the color of the stones changes so much once you thin them down with the pavilion and girdle cuts, before the internal refraction can intensify the color. It's always amazing to me how the color changes so dramatically once you add in the facets on the crown. Looks like these might be close to a Ceylon sapphire coloration, which is a subtle and beautiful color.
They turned out amazingly well and there's barely any difference between the two. I'm sure Bopie will be quite happy to find a setting for the second one.
Cost effective? Well, maybe, but the pulled method is about 100 times more expensive than the 'flame fusion' method for corundum. But the problem with ceylon colored flam fusion corundum is that the color is all in the 'rind' of the boule, the center is clear. So Flame Fusion is cheap....but for BLUE Corundum, you have to orient the stone so that it picks up the color from the 'rhind'. Pulled method is an option, but it's much much much more costly then flame fusion.
Beautiful Sapphires' and setting/ring!
Thank you!
Thanks a lot ! Sharing is Caring !!!
You are welcome.
Incredible as always, thank you for making these videos, one of these days I hope to be able to cut stones like that.👏
Thank you. I am sure you will cut much better than I do. Best of luck!
Hi Mike loved them both great to see it set thank you very much
Thank you!
Hi Mike, very nice to see the setting. I've been in touch with the super glue company and for some reason they won't supply Australia with stock. I'm using normal super glue and its annoying waiting 24 hours before I can start faceting. I also use wax buts its been hard to get lately.
Hi. I have heard from some faceters that they have had luck with other brands of UV activated superglue. I have only tried one brand, Bondic, and it did not work at all. But maybe you can find a different brand? I can't imagine why wax would be hard to get, but I never got the hang of using wax. I do know that wax is the favorite of half...ok, probably more than half...ok, more than half of gem cutters. 🙂
Very nice, That stuff must be easier to cut than trying to line up the flame fusion rind colour.
Bingo. The second reason I needed to use rough created by the pulled or Czochralski method is exactly as you stated. The odd thing about blue (and only blue) corundom (sapphire and ruby) crated using the flame fusion method is that the blue color is all in the outer 'rind' of the boule. The inner part is colorless. So you have to cut your blue sapphire so that some of the 'rind' is in the final gemstone and captures the blue. For my upcoming special project, I need no color zoning...blue throughout the gemstone. So flame fusion is out. ...and also boules are not large enough for my project.
Hello.
Good job! I like these Barion pavilions on sapphires.
In my work, I also constantly follow the MeetPoint technic at my UT.
But when it comes to stones smaller than 3 mm in size, forming a girdle becomes very painful...
I'm thinking about buying Offset Attachment from UltraTec and making small stones the old way, without MeetPoint, but I'm worried that it may not be possible to save time, since I will have to almost manually adjust all the angles.
What do you think?
Thanks. I have not tried the offset attachment from UT so I can't really talk about it. I do cut small stones on occasion and think it is good practice to cut a small stone once in a while. To me, they cut the same as a larger stone, and normally, smaller stones polish easier than larger stones, at least that is my experience. I would not change the designs you are using for stones, but if for some reason you are having problems with girdles, there must be a reason...I'd say you should cut a few more while focusing on trying to isolate the issue with the girdles. Maybe you are overcutting because of the size of the stones?
@mikesackos2208
Thank u for your reply...
I can create it...
Nevertheless, it takes the same time, like for larger gems...
But the price for tiny stones can't cover the time which you spend for meetpoint method...
It is concerned tiny gems only...
So, I'm trying to find the way to cut down the time ...
@@evgenyk.4681 Yes you make a valid point.
Hey Mike - Where did you get this rough. I need a to get some sapphire rough for a project I am working on. Thanks
Happy to help. Just contact me via PM on Facebook (Mike Sackos).
Mike when using the Helios, how do you release the first dop after transferring to cut the table?
Normally with heat. I wrap the stone in a piece of wet paper towel. Then, I normally clamp it into my small vice with the dop that I want to remove sticking out. Then I use a Butane torch and heat that dop for a second or two and it comes right off. I may have to scrape a little glue off the stone with a box cutter but that's about it.
@@BOPIESDiamondsFineJewelry thank you. I usually dop with wax. Curious about trying the Helios
