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. (Our 4mm size 7 is out of stock until about 9/30/20.)
Note: ring blanks may have the size and/or material type laser-engraved on the interior.
all quality items. love working with your rings
The ring blank is awesome! I tried to use some black obsidian powder with glow powder to install some fire opal and the surface finish was not good. I really like experimenting with different products to see what the results might be. Oh well with the black ceramic ring core I was able to drop the ring into some acetone and start over. Thank you for supplying such excellent products and services.
It is very easy to work with and looks great
Excellent ring blank great customer service. Always there answer any questions you have. Will be ordering more
I love working with the ceramic ring blanks. They are so smooth and comfortable. They are super scratch resistant, so sanding does not hurt them. I was not happy with my first attempt at making a ring, so I was able to turn the ring in my lathe and take the filler material out and start over again. I highly recommend the ceramic ring blanks.
