Ruby abrasive stones are made from sintered crystals of synthetic ruby.
They are extremely hard, maintain their shape well and are resistant to wear.
Because they are so hard they can sharpen and finish extremely hard metals such as carbide gravers, but also work on non-metal like glass, porcelain and quartz.
