Kutnahorite (Kutnohorite) - Sold


Kutnohorite, originally named after Kutná Hora in Czechia (Bukowský, 1901). Frondel & Bauer (1955) and the authors of the seventh edition of Dana's System of Mineralogy attempted to change the spelling to kutnahorite, to more closely match the type locality name. Nevertheless, this spelling change has not been generally accepted. Kutnohorite is a member of the dolomite group, specifically a calcium manganese carbonate. It is popular among collectors for its tendency to form sheaves of crystals, like in this example. This specimen is an aggregate of sheaves, structured much like a cauliflower. This particular example has better color than most from a rather recent find at the Wessels mine. A true mineral oddity!
