Anhydrite, including angelite, is an inherently unstable stone that absorbs moisture at the drop of a hat. It can also be easily marred, so protect it from scratches, sharp blows or large temperature changes that will fracture, shatter or chip it. When anhydrite--a soft mineral--is exposed or immersed into water, it transforms into gypsum.
