History:A relatively recent discovery in the mineral and gem world, angelite was discovered in 1987 in Peru. The name anhydrite 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." The name Anhydrite was given by A. G Werner in 1804, due to the absence of water in crystallization which is contrasted to the presence of water in gypsum. |
