description Cobaltocalcite Overview
Cobaltocalcite, also called cobaltoan calcite, is a cobalt-rich variety of calcite whose cobalt content commonly produces pink, rose, or red coloration. It is associated with hydrothermal mineral deposits and is especially familiar from collector specimens from the Democratic Republic of the Congo. Because calcite is relatively soft and has prominent cleavage, cobaltocalcite is used mainly as a mineral specimen or ornamental material rather than as a durable everyday jewelry stone.
