Lapis Lazuli Slabs Page 1
Lapis has been prized as a gemstone since ancient Egypt. It cuts easily and polishes with tin or chrome oxide, with a tiny bit of aluminum oxide type A mixed in. In order to obtain a higher polish, it can be given a final polish with Zam or waxed. Lapis usually has pyrite in it.
