description Magnesite Overview
Magnesite is a mineral composed primarily of magnesium carbonate, with the chemical formula MgCO3. It commonly occurs in white, grey, or pale brown masses and has a dull to glassy appearance, although some material is cut and polished for ornamental objects and jewellery. Magnesite is also frequently dyed blue and sold as an imitation turquoise, so colour alone is not a reliable way to identify it. It forms in several geological environments, including altered ultramafic rocks and sedimentary deposits.
