Black ceramic is a beautiful material. The material is very hard and doesn't scratch easily. It provides a lustrous background for any inlay.

Ceramic is a brittle material that can crack if it experiences a sudden impact or is stressed (as with an expanding ring mandrel).  To prevent this, we recommend using two layers of electrical tape wrapped around the mandrel instead of over-tightening.  If the ring still slips, use two dabs of CA glue to glue it to the mandrel rather than over-tightening the ring on the mandrel.

Rings are available in standard 8mm or thinner styles of 6mm and 4mm. 

The channel on the 8 mm ring blanks is 1 mm deep and 4 mm wide.  Our 6 mm-wide rings have a channel that is 1 mm deep and 3 mm wide.  Our 4mm-wide rings’ channel is 1 mm deep and 1.9 mm wide.

Note:  ring blanks may have the size and/or material type laser-engraved on the interior.

This is a nice and durable core

I made a purple heart ring with a cutout for opals in the center. Core worked fine, even using it a 2nd time! In trying to get that perfect thickness I blew up a first attempt on the lathe. I soaked core in acetone and it cleaned off perfectly for a second use. Not a scratch on It. Grand daughter loves the ring.

The Black ceramic Ring is all that it promises, great shine, pretty scratch resistant while Sanding, and if you have a few mishaps, the diamond polishing paste will fix that in a Heartbeat.

My favorite rings to work with are the ceramic rings. They don't scratch and polish up so nicely.
