QUIRKY WORLD ... Diamond the size of a tennis ball could fetch €60m in sale

Britain: A London auctioneer says a diamond the size of a tennis ball, that is the largest discovered in more than a century, could sell for more than $70m (€60m).

Sotheby’s says it will offer the Lesedi la Rona diamond in London on June 29.

The diamond was unearthed in November in Botswana at a mine owned by Canada’s Lucara Diamond Corporation. It measured 1,109 carats, making it the second-largest gem-quality rough diamond ever discovered. Its name means ‘Our Light’ in the Tswana language.
