Rhodonite

Rhodonite

Relatively common mineral named after the Greek rhodon for “rose,” describing the mineral’s rose red color. Hundreds of localities have rhodonite in manganese hydrothermal, contact and regionally metamorphosed, and sedimentary deposits.  Exceptional specimens come from Russia, Sweden, England, Romania, Italy, Australia, Japan, the USA, Brazil and Peru.
