This mine, which is located in the East Kimberley region of Western Australia, was also the first mine to exploit a volcanic pipe of lamproite successfully.
Interestingly, the Argyle Diamond Mine is not famous for any one of the above-mentioned facts; instead, it is famous for the production of argyle
diamonds. In fact, this mine is also considered as a significant source of pink
diamonds. In addition to that, large deposits of cognac, blue, and champagne
diamonds are also found in this mine.
The unique composition of Argyle
diamond rings is because of a volcanic pipe or
Argyle pipe, which is made of olivine lamproite. The
center stone of
diamond argyle
rings gets interacted with a number of minerals such as mica, zeolite, clay, and kaolinite during the formation process. In addition to that, most of these
diamonds also contain nitrogen impurities. However, the elegant pink color of Argyle
diamond rings is due to the structural defects in its crystal lattice.
