Coloured Calcite

Calcite is a common mineral that is found in a variety of colors and forms, including colored calcite. Colored calcite can come in shades of pink, orange, yellow, green, blue, purple, and brown, and is often found in crystalline or massive form.

The color of calcite is determined by the presence of impurities or other minerals in the crystal structure. For example, pink calcite is often colored by the presence of manganese, while green calcite can be colored by the presence of copper. Blue calcite can contain small amounts of copper, while yellow and brown calcite can contain iron or other trace elements.
