PICS: World's largest diamond to go on sale

JOHANNESBURG - An intensely pink diamond, described by experts as the world’s largest, is expected to fetch up to $30 million next week in Geneva.

The precious stone weighs just over 37 carats and was mined in 2015.

The seller remains anonymous.

Previous sales for smaller pink diamonds have yielded just over a million dollars per carat.

The auctioneers say the rarity of the stone is attracting plenty of interest.

According to David Bennett of Sotheby’s International Jewellery, only a fraction of all the diamonds mined in the world have any tint of pink and to have one this colour is phenomenally rare.
