Bowenite is a hard, compact variety of the serpentinite species antigorite, (Mg3(OH)O4Si2O5). Classed as semi-precious gem stone it has been used for tools, weapons and jewellery by the Māori in New Zealand, and for jewellery by Fabergé. Deposits are found in several places around the world including Afghanistan, China, New Zealand, South Africa and the United States. It typically ranges in colour from dark green to light olive green, and in shades approaching yellow. Bowenite was named by James D. Dana in 1850 after George T. Bowen, who analyzed it in 1822.
