About Petra Diamonds Ltd.

Petra Diamonds Ltd. is a diamond mining group with interests in a number of diamond mines in South Africa, including the distinguished Cullinan, Finsch, Kimberley and Koffiefontein mines. Williamson Mine in Tanzania also forms part of the Group. Some of the world’s most unique diamonds were uncovered at the Group’s mines, like the world’s largest gem diamond, the Cullinan diamond, which is 3,106 carats rough. Cullinan mine is renowned for its rare blue diamonds, while Williamson mine is known for its ‘bubblegum pink’ gems.

Going forward, Petra Diamonds has developed expansion programmes that will create a new sub level and block caves in undiluted kimberlite. Moving to undiluted ore will mean that Petra Diamonds will increase their grade, be able to uncover higher quality diamonds and enhance their margins.
