  • Beautiful
Size: 9.5 Color: 8mm Hammered Black Ceramic
I have not finished this one yet but it looks even better in person than the picture. Nice smooth finish and beautiful shine. Size is correct if using a ring sizer to order the size you want.

  • Almost held up to sanding
Size: 6.5 Color: 6mm Black Ceramic
This is the first time I've ever done anything like this. I put in a 2 part epoxy inlay. After the curing I used Testers wet sanding paper of different grits by hand. Some portions of the black ceramic look a bit lighter but it still feels smooth. I polished it with car wax. The ring has been through daily showers, dish washing, and obsessive hand washing and it still looks great a few months later. Overall a very economical way to get into ring making with minimal equipment ... show more

  • Only gave four stars so people wouldn't think I was paid off
Size: 8 Color: 8mm Domed Tungsten
It was exactly what I was looking for. I just got into ring turning as a hobby and I was getting tired of the flat top, beveled edge blanks everyone else sells. I don't really like double channels either so this was a blessing. Although my handy work could be better, the project came out well enough that I replaced my wedding ring with what I made using the domed tungsten blank. I will say, I've bought a couple different blanks at this point from this page and this one fits more snugly than some of their other options so maybe buy a half size bigger than usual. I've been wearing it for about two weeks now and there's not a scratch on it and it's as shiny as the moment I finished polishing. Be sure to use a good ca adhesive, though. ... show more

  • Great basis for a ring
Size: 10 Color: 6mm Domed Tungsten
I had a vision to make a ring with a Lapis fill. This ring blank became the basis for my vision. The process steps to fill the ring went well. The turning processes went easily and comfortably, I did not scratch the very tough ring stock. It polished readily with the lapis being the focal point, however the ring itself took a good finish as well. ... show more

  • As advertised
Size: 8.5 Color: 6mm Black Ceramic
The media could not be loaded. What I ordered is what came in the mail so guess can’t ask for or expect anything more than that overall satisfied

  • Study. Accurately sized. Wonderful!
Size: 12.5 Color: 8mm Flat Edge Black Ceramic
Held up great to sanding! I’ve never made jewelry before so I was very nervous it would get scratched up. I got a size 8.5 and 12.5 for my husband and brother to make memorial jewelry with my dads ashes. I added crushed green and black Opals to this one and it looks awesome!
