Gypsum desert rose. Origin: Coahuila - Chihuahua - Mexico. Gypsum sometimes forms in sandy areas, and crystals may trap sand inside when forming, causing a specimen to become brown or gray and opaque. These sand inclusions sometimes form hourglass formations in a crystal. They are also present in the well-known “Desert Rose”, which is rosette shaped Gypsum with sand inclusions.
