* Using the term “chrysoprase” to describe this material is a deceptive practice. Chrysoprase is a variety of the species Chalcedony, a cryptocrystalline aggregate form of the mineral quartz (SiO2). Magnesite is a magnesium carbonate mineral (MgCO3). Chrysoprase and green Magnesite, also known as Nickeloan Magnesite, are often found in the same deposits, and many specimens are a mix of the two materials. Both are colored by traces of Nickel.
