Dolomite

Dolomite is found as colourless, white, pink, or yellow crystals, often with distinctive curved faces. Rarely faceted, due to its softness and perfect cleavage, its main use is in massive form, as a decorative stone.

Found in limestones and marbles, the best dolomite crystals are from Italy, Switzerland, Germany and United States.
