This is the biggest blue diamond to ever be auctioned
The rare blue Oppenheimer diamond is expected to be sold for up to AUD$58 million when it goes to auction next month.
Also known as the 'gem of gems,' the 14.62 carat diamond is the largest to ever be auctioned and will be sold by Christie's on 18 May in Geneva.
The Oppenheimer Blue was named after its previous owner, Sir Philip Oppenheimer, a diamond dealer whose family owned the diamond company De Beers.

The unique rectangular-shaped gemstone is called a ‘Fancy Vivid’ diamond because of its rare and deep blue colour.
According to previous studies of blue diamonds, which account for 0.1% of diamonds mined around the world, one per cent of them are Fancy Vivid.
The chairman of Christie's Asia Pacific and China, Francois Curiel, says Sir Philip chose to own this particular demand for its “perfect hue, impeccable proportions and fabulous rectangular shape.”

Having controlled the Diamond Syndicate in London, Sir Philip could have had any diamond in the world, but he had his eye on this rare beauty for obvious reasons.
The Oppenheimer blue has been valued between $49 million and $58 million and will be the centrepiece at Christie's Magnificent Jewels sale at the Four Seasons Hotel des Bergues, Geneva.
“The Oppenheimer Blue can only be described as one of the rarest gems in the world,” says Curiel. “It is the gem of gems.”
