Lesotho unearths 478 carats stone

The gem which was discovered on 8 September in Lesotho and not yet named, it is already 20th largest rough diamond found, and if cut and polished, could be the largest ever polished round diamond, weighing in at 150 carats, according to diamond specialists.

The mine, which was owned by De Beers for many years, has already produced three of the world’s biggest diamonds. These are the 603-carat Lesotho Promise, 493-carat LetÅ¡eng Legacy and the 601-carat Lesotho Brown.

Experts in Antwerp, Belgium, who analysed the 478-carat stone determined it to be of the highest color grading available for a white diamond, said a statement from Gem Diamonds Ltd., the company that found the stone.

“What makes it more remarkable is the color and quality of this stone,” said diamond consultant Neil Buxton, further stating that it is a D color, which is highest possible graded color which could produce over 100 carats.

Clifford Elphick, Gem Diamonds’ chief executive, said: “Preliminary examination of this remarkable diamond indicates that it will yield a record-breaking polished stone of the very best colour and clarity.”

The Letšeng mine is owned by a mining company that is 70 percent owned by Gem Diamonds, with remaining 30 percent held by the Lesotho government.

Mr Elphick said Letšeng continues to reward its shareholders with production of significant diamonds and to confirm its position as one of the great mines in diamond industry.

“With a further 45 years of life remaining, we expect LetÅ¡eng to make history for many years to come.”  LetÅ¡eng Diamond mine was reopned in 2005 after years of inactivity. – afrol News
