These ceramic ring cores provide easy entry into the exciting world of ring turning. Just turn a hole into a wooden or acrylic ring blank (sold separately), glue it around the exterior of the ring core, mount it to your lathe with one of our Ring Mandrels (e.g. #66111, sold separately) and after a quick spin, you'll be rewarded with a beautiful one-of-a-kind ring. These cores are made with a thin profile and a smooth, convex contour on the interior for comfort. The black ceramic material is exquisitely smooth, completely hypoallergenic, and extremely scratch-resistant.
