Huge 'Constellation' diamond unveiled in Paris


The world’s most-expensive unpolished diamond at the time of sale has been unveiled in a Paris exhibition.

Swiss jewellery maker Grisogono displayed the 813-carat gem, which was bought for over 60 million US dollars – around 56 million euros.

Canadian miner Lucara Diamond sold the stone after unearthing it in Botswana last year.

It has been named ‘Constellation.’
