MINING group Rio Tinto has unearthed an extremely rare pink diamond, Australia's biggest rough pink diamond weighing 12.76 carats at its Argyle mine.
More than 90 percent of the world's pink diamonds come from the Argyle mine in the East Kimberley region in the far northeast of Western Australia.
The diamond, discovered in the Argyle open pit, will be known as The Argyle Pink Jubilee, Rio Tinto said.
It is a light pink diamond, similar to The Williamson Pink, the diamond Britain's Queen Elizabeth received as a wedding gift and which was later set into a brooch for her coronation.
Diamond polisher Richard How Kim Kam, who has worked for Argyle for 25 years, has begun polishing the diamond in Perth.
After two months of careful assessment and planning, it will take about 10 days to cut and polish it as a single stone.
Richard said: "I'm going to take it very carefully. I know the world will be watching."
Afterwards it will be graded by experts and promoted before being sold as part of the Argyle pink diamonds tender later this year.
Argyle pink diamonds manager Josephine Johnson said: "A diamond of this calibre is unprecedented - we may never see one like this again."
Christie's has auctioned 18 polished pink diamonds over 10 carats in 244 years.
