The Cempaka mine is one of the largest diamond mines in Indonesia and in the world.[1] It's one of the oldest known sources of diamonds globally.[2] The mine is located in South Kalimantan, Borneo and is the only diamond deposit in Kalimantan that has been mined on a commercial scale.[3] The mine has estimated reserves of 32.9 million carats of diamonds.[1] Frequent land slides are a problem.[4]
The Gem Diamonds Group placed the Cempaka diamond mine on care and maintenance in 2009.[5] Subsequent limited public news and data from the Kimberley Process regarding Indonesian diamond production and export, suggests the mine has not yet restarted commercial production.[6]
