Mineralpedia Details for Rhodizite
Rhodizite
Named after the Greek rhodizein, meaning “rose-colored” or “to be rose-colored” as its presence in a flame will turn the flame red. Rhodizite is a rare mineral found as an accessory mineral that formed late-stage in granite pegmatites. It has localities in Russia, Madagascar, England, and the United States only. Rhodizite is highly piezoelectric, produces a charge in response to pressure, and pyroelectric, produces a charge in response to heating.
