This diamond the size of a tennis ball could be yours...for $70 million
A diamond the size of a tennis ball is set to be auctioned at Sotheby's in London later this month.
But if you want to buy the sparkler you'll have to dig deep: the diamond is expected to fetch $70 million, roughly £49 million.
The 1,109 carat 'Lesedi la Rona' was found in Botswana last November, and is the largest gem quality diamond in existence today.
The diamond was discovered by Lucara Diamond Corp at their Karowe mine, and could be more than 3 billion years old.
Sotheby's jewellery division chairman David Bennett called it "the find of a lifetime." He added: "No rough even remotely of this scale has ever been offered before at public auction."
A competition to name the diamond received more than 11,000 entries when it was opened to Botswana citizens.
'Lesedi la Rona' means 'Our Light' in the Tswana language spoken in Botswana. The winner said he chose the name because "the diamond is a pride, a light and a hope for Botswana".
Lesedi la Rona will be on display at Sotheby's in London ahead of the sale on June 29.
