Bowenite
Together with nephrite jade the Māori class bowenite as pounamu, 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. Historically it was used for tools, weapons and ornaments, although modern use is limited to jewellery, such as Tiki. The South Island deposits are legally protected, and taking material without Ngāi Tahu permission has led to prosecutions. In 1992 Ngāi Tahu approved the 'Pounamu Resource Management Plan' to manage deposits of this commercially valuable resource. Bowenite is the  state mineral of the U.S. state of Rhode Island. 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 elaborate designs.
