It crystallizes in the trigonal system, typically as rhombohedral crystals with characteristic curved, saddle-shaped faces, showing vitreous to pearly luster, perfect rhombohedral cleavage, and a hardness of 3.5–4. Colors range from colorless and white to yellow, brown, and, when enriched in manganese or cobalt, delicate pink to vivid magenta.\u003c\/p\u003e\u003cp\u003eClassic localities include the \u003cstrong\u003eAzcárate Quarry\u003c\/strong\u003e at \u003cstrong\u003eEugui\u003c\/strong\u003e, Navarra, Spain, source of some of the world's finest transparent, gemmy rhombohedra; the \u003cstrong\u003eTri-State district\u003c\/strong\u003e of Missouri, Oklahoma, and Kansas, famed for creamy curved crystals with galena and sphalerite; \u003cstrong\u003eBrumado\u003c\/strong\u003e, Bahia, Brazil, known for large twinned crystals; and the \u003cstrong\u003eLengenbach quarry\u003c\/strong\u003e at Binntal, Switzerland.
