Garnierite, sometimes referred to as Green Moonstone, is a common name for green nickel magnesium ores. It is not recognized formally as a distinct mineral because its chemistry varies greatly. Garnierite is created by the weathering of ultramafic rocks like serpentine in tropical environments. Deposits of Garnierite have been found in South Africa, The Dominican Republic, Oregon, and several other locations. The appearance varies in each deposit.
Chemical Formula: (NiMg)6Si4O10(OH)8
