Where does Rhodonite come from?
Rhodonite deposits are found in Australia, Canada, Finland, Japan, Madagascar, Mexico, Peru, Russia, Sweden, South Africa, Tanzania, and the United States (New Jersey).
What is Rhodonite?
Rhodonite is a rare type of manganese silicate. Silicate minerals form the largest family of minerals, including more than 25% of all known minerals and 40% of all common minerals. In addition to being a major part of the Earth’s crust, Silicate minerals have also been found on the moon and in meteorites. Silicates are minerals which contain the elements Silicon (a light gray shiny metal) and Oxygen (a colorless gas). Together, these two elements form a tetrahedron – a shape similar to a pyramid – with a Silicon atom in the center and Oxygen atoms at each of the four corners. These tetrahedra connect with other chemical structures, in six different ways, to form various minerals and rocks. One way the tetrahedra can connect is in long single chains, and it is to this group that Rhodonite belongs. Other famous minerals in the single-chain group are Astrophyllite, Jadite, Kunzite and Nuumite.
Rhodonite is formed during the metamorphosis of sedimentary manganese ore deposits, a process which creates the rose color. If the rose colored stone is then partially oxidized through weathering it creates black patches and veins of manganese dioxide.
How is Rhodonite mined?
Rhodonite is typically mined alongside various manganese ores. Depending on the quality and size of the Rhodonite deposit, it may be mined specifically as a gem or ornamental stone.
What minerals are found with Rhodonite?
Rhodonite is often found associated with Calcite, Galena, Pyrite, Quartz, Rhodocrosite and Spessartine Garnet
Is Rhodonite natural?
All Rhodonite is natural, enhanced only by tumbling, cutting, and polishing.
