....It has a defining Mohs hardness of 3, a specific gravity
of 2.71, and its luster is vitreous in crystallized varieties. Color is
white or none, though shades of gray, red, orange, yellow, green, blue,
violet, brown, or even black can occur when the mineral is charged with
impurities.....

This shot shows its vitreous luster. This mineral will dissolve in acid. Its color comes from impurities. It is soft and therefore not used as a gem. This sample came from Mexico.
