Black ceramic 2, 3, 4mm inlay channel ring core

These ceramic comfort cores are consistently sized, cleanly finished, and make a great foundation for inlays. I’ll definitely keep using these for custom ring builds.

I love ceramic! Hard material means it’s easy to get close hard to scratch, you can ride the core without fear. But I’ve also broken a few with the steel expanding mandrel, do not overtighten. 10/10
