Angelite

Angelite
Angelite is a trade name for blue anyhdrite - a calcium sulfate mineral related to gypsum. Angelite is very soft, with a hardness of 2 on the Mohs scale. It is unsuitable for use in jewelry because it will be easily abraded or broken. It has a very nice blue color, which is often produced with dye.

A relatively recent discovery in the mineral and gem world, angelite was discovered in 1987 in Peru. The name ahnydrite comes from the Greek anhydras --meaning "without water"--a reference to angelite being a gypsum that has completely lost all hydration, becoming a stone that is "without water."
