Rhodonite is a manganese inosilicate, with the formula (Mn, Fe, Mg, Ca)SiO 3, and member of the pyroxenoid group of minerals, crystallizing in the triclinic system. It commonly occurs as cleavable to compact masses with a rose-red color (its name comes from Ancient Greek ῥόδον ( rhódon ) ' rose ' ), often tending to brown due to surface ...
The name is derived from the Greek "rhodon" for "rose-like", in common with other pink mineral types (such as rhodochrosite, rhodonite). This coloration, and the commonly inclusion-free nature of garnet from this locality, has led to rhodolite being used as a gemstone. Rhodolite like other varietal names is not officially recognized as a ...
Minerals are distinguished by various chemical and physical properties. Differences in chemical composition and crystal structure distinguish the various species. Within a mineral species there may be variation in physical properties or minor amounts of impurities that are recognized by mineralogists or wider society as a mineral variety.
Rhodochrosite is a manganese carbonate mineral with chemical composition MnCO 3.In its pure form (rare), it is typically a rose-red colour, [5] but it can also be shades of pink to pale brown.

Pyroxmangite has the general chemical formula of MnSiO 3. [5] It is the high-pressure, low-temperature dimorph of rhodonite. [2]It was first described in 1913 and named for the mineral group, pyroxenes, and is known as the manganese member. [6]
Bustamite is moderately common there and occurs in a variety of assemblages, associated with rhodonite and tephroite, calcite and tephroite or glaucochroite and tephroite. Vesuvianite, wollastonite, garnet, diopside, willemite, johannsenite, margarosanite and clinohedrite also may be present.
