THE CONSTELLATION

The world’s most expensive rough diamond

de GRISOGONO ACQUIRES THE CONSTELLATION, THE WORLD’S MOST EXPENSIVE ROUGH DIAMOND

The Constellation

To mark the opening of the 28th Biennale des Antiquaires, de GRISOGONO announced the acquisition of The Constellation, the world’s most expensive rough diamond. The purchase represents a ground-breaking moment for the company in its journey to become one of the world’s leading high jewellery and watch brands.
Measuring over six centimeters wide, The Constellation weighs 813-carats and was discovered by Canadian company, Lucara Diamond, at its Karowe mine in Botswana in November 2015. The gem was purchased for USD63 million earlier this year, following a competitive bidding process.

The Constellation naturally boasts the colour, clarity and carat weighting of an internationally and historically significant stone. It is expected that the cutting process, due to be completed by the middle of 2017, may unveil one of the world’s largest certified flawless diamond.
