Sydney: Mining giant Rio Tinto said on Wednesday it has unearthed a "remarkable" 12.76 carat pink diamond in Australia, the largest of the rare and precious stones ever found in the resources-rich nation.
Named the Argyle Pink Jubilee, the huge rough stone was found at Rio`s pink diamond operations in the Kimberley region of Western Australia and would take 10 days to cut and polish, the company said.
"A diamond of this calibre is unprecedented -- it has we may never see one like this again.
"The individual who gets to wear this remarkable pink diamond will be incredibly lucky indeed", the company said.
Though it would not speculate on how much the Jubilee was worth, Rio said extremely high quality pink diamonds could fetch in excess of USD 1 million per carat, meaning it is likely to go for at least USD 10 million.
Soaring demand for the extremely rare jewel has seen pink diamond prices skyrocket in the past 20 years and they are now among "the most concentrated forms of wealth on earth and well in excess of white diamonds," Rio said.
The miner describes it as an "elite and discrete" market with buyers including royalty, heads of state, celebrities and "other very wealthy individuals."
When the Jubilee diamond has been cut and polished it will be graded by international experts and showcased globally in private settings before being sold by invitation-only tender later this year.
