Mineralpedia Details for Chrysoberyl
Named after the Greek word chryso, which means “golden,” in reference to the mineral’s typical color, and likely after the beryllium content of the mineral, although most sources will tell of it being named after the Greek beryllos, which means “beryl,” despite the fact that Chrysoberyl and beryl are two completely unrelated minerals. Chrysoberyl is an uncommon mineral, but widespread and notable localities include in Brazil, the Czech Republic, Russia, Madagascar, Zimbabwe, Sri Lanka, and the United States. Chrysoberyl can be found in granite pegmatites and as a detrital mineral.
