Bowenite

Bowenite is a hard, compact variety of the serpentinite species antigorite (Mg3(OH)O4Si2O5).

[5] Deposits are found in several places around the world including Afghanistan, China, New Zealand, South Africa and the United States.

[citation needed] Together with nephrite jade the Māori class bowenite as pounamu,[4] which is also known as greenstone, and is of particular significance to the Ngāi Tahu iwi on whose traditional lands on the South Island of New Zealand most deposits are found.

[1] Historically it was used for tools, weapons and ornaments, although modern use is limited to jewellery, such as Tiki.

[7][8][9] The South Island deposits are legally protected, and taking material without Ngāi Tahu permission has led to prosecutions.
