Calcite

Calcite is found all over the world in a variety of forms and colours, often in combination with other minerals. The more common forms of Calcite are Orange, Blue, Green and Yellow; Iceland Spar is a clear double refractive variety that forms natural rhomboids. Mangano Calcite is a rare pink variety, with high quality specimens from Peru displaying pink and white banding. Black Calcite, also known as Shamanite, is another rare variety. Interestingly, Calcite and Aragonite are identical in chemical makeup, but crystallize differently to give us different crystals.
