Where they're mined
Argyle diamonds are mined exclusively in the Argyle Diamond Mine in the East Kimberley region of Western Australia. The mine sits on the traditional country of the Miriuwung, Gidja, Malgnin and Wularr people. The mine was opened in 1983 and at its peak year of production mined 40% of the world's diamonds. In 2020 it closed permanently, and given only a small percentage of its yield were deemed gem quality, Argyle diamonds are extremely rare and valuable.
