Physical properties
Hardness of 3.5 to 4 on the Mohs scale, distinct pink to rose-red color, vitreous to pearly luster, and trigonal crystal system with perfect cleavage.
Formation & geological history
Formed in hydrothermal veins associated with silver, lead, and copper sulfide ores, as well as in sedimentary manganese deposits.
Uses & applications
Primarily used as an ore of manganese, in ornamental carvings, and as a popular gemstone in jewelry and collector specimens.
Geological facts
Known as the 'Inca Rose' because ancient Incas believed it was the blood of their former rulers turned to stone, and it is the official provincial stone of Argentina.
Field identification & locations
Easily identified by its characteristic pink color banding and reactivity to hydrochloric acid; commonly found in Argentina, South Africa, and the USA.
