Lazulite

Lazurite is often confused with the very similarly named Lazurite, which is a component of Lapis Lazuli. This confusion is furthered as they are both blue crystals! It was first discovered in 1795 in Austria, and named after the german word 'lazurstein' meaning heaven, after it's blue sky shades. It is rarely found in well defined crystals, instead it can be found in association with other minerals, namely Quartz.
