Pounamu pendant

Together with nephrite jade the Māori class bowenite as pounamu, which is also known as greenstone, and is of particular significance to the Ngai Tahu iwi on whose traditional lands on the South Island of New Zealand most deposits are found1 Historically it was used for tools, weapons and ornaments, although modern use is limited to jewellery, such as Tiki456 The South Island deposits are legally protected, and taking material without Ngai Tahu permission has led to prosecutions7 In 1992 Ngai Tahu approved the 'Pounamu Resource Management Plan' to manage deposits of this commercially valuable resource8

Bowenite is the state mineral of the US state of Rhode Island2

Most deposits of bowenite are small, although a large deposit was discovered in South Africa in 1989 Deposits in China are in the Suzhou region, which accounts for its also being known as Suzhou jade with carving in ellaborate designs9
