SYDNEY, Feb. 21 (Xinhua) -- Australia's largest pink diamond ever found by mining giant Rio Tinto will be cut and polished by the company's expert diamond cutter Richard How Kim Kam, local media reported on Tuesday.
The 12.76 carat gem was discovered at Rio Tinto's Argyle mine in the east Kimberley region of Western Australia.
The pink diamond which will be known as the Argyle Pink Jubilee is to be cut and polished as a single stone by How Kim Kam.
"I'm going to take it very carefully," How Kim Kam told the Australian Associated Press (AAP).
"I know the world will be watching," he said.
The finished gem will be graded by a team of international experts and shown around the world before being sold under a tender process later in 2012.
Argyle Pink Diamonds manager Josephine Johnson said a diamond of its level was extraordinary.
"It has taken 26 years of Argyle production to unearth this stone and we may never see one like this again," Johnson said.
