Dolomite is a carbonate mineral composed of calcium and magnesium. It is named after the French geologist Déodat Gratet de Dolomieu who discovered it in Northern Italy in 1791.

The most beautiful Dolomite crystals come from the vicinity of Eugui in Navarre (Northern Spain). A Spanish stamp from 1995 celebrates the minerals of Spain (minerales of España) and features crystals of Dolomite.
