Luxury jeweller Graff has acquired the 14th largest diamond ever mined – the Peace Diamond – for $6.5m (£4.8m).

Before the year closes, Graff Diamond’s chairman, Laurence Graff, has added another significant stone to its portfolio.

Purchased at an international auction held by the Rapaport Group, all proceeds from the sale will benefit the country, village, and community where the stone was found.


At 709cts, the Peace Diamond is the second largest rough diamond ever discovered in Sierra Leone.

The stone was unearthed near the village of Koryardu by a team of five artisanal diggers supported by the village pastor, Emmanuel Momo.

Commenting on this gesture, pastor Emmanuel Momo, says: “The Peace Diamond will greatly improve the lives of our people as it will bring clean water, electricity, schools, medical facilities, bridges and roads to our villages and the Kono District.

“This diamond represents our hope for a better future as the resources of Sierra Leone fund growth, development and jobs.”

The acquisition of the Peace Diamond continues a recognised investment from Graff Diamonds and Laurence Graff in giving back to diamond producing countries of Africa.

“It is an honour to have acquired this magnificent rough diamond – and that its sale will directly benefit a country in desperate need,” shares Graff. “It is always special to be able to give back to the places that provide us with these beautiful stones.”

Graff’s expert team of gemologists will now begin to assess the internal qualities of the swtone.

“Who knows the story that the Peace Diamond will tell in years to come.  At this moment, the story of this diamond marks an important chapter for the people of Sierra Leone,” Graff adds.

Earlier this year, Graff purchased the world’s most valuable rough diamond – the Lesedi La Rona – weighing a record-breaking 1,109 carats, preceded by a remarkable 373 carat diamond was originally part of the Lesedi La Rona rough.
