“We believe in the superior craftsmanship of our Belgian Master Cutters”
jean_claude_muller_x.jpgS. Muller & Sons founded in 1955 is now a world-renowned diamond manufacturer managed by the third generation of diamantaires led by Jean Claude Muller, the company’s CEO. S. Muller & Sons has an in-house diamond factory, one of the few that still remain in Antwerp, which is producing the now famous Hearts & Arrows Diamonds. The company’s involvement in Hearts & Arrows initiated with its relationship with Mr. Takanori Tamura, the inventor of the Eight-Star Diamond. While attending the Antwerp Diamond Trade Fair last February, our correspondents – helped by the Antwerp World Diamond Centre and S. Muller & Sons - took an opportunity to visit the company’s diamond factory, which resulted in the interview with Jean Claude Muller below.

The envisaged new deal would replace a 2007 agreement that allowed De Beers to sell the stones through the Namibia Diamond Trading Company (NDTC), a joint venture between Windhoek and De Beers. Namibia’s mines and energy minister Isak Katali told Rough & Polished’s Mathew Nyaungwa on the sidelines of a mining conference in Cape Town recently that the negotiations are now envisaged to end in June this year, if not earlier.

Petra to produce 1.5m ct per year at newly-acquired Finsch Diamond mine

10.02.2011

Petra Diamonds, which recently acquired Finsch Diamond mine from De Beers, said it will produce 1.5 million carats annually.
Company chief executive Johan Dippenaar told the ongoing Mining Indaba in Cape Town that this was lower than the 2 million carats De Beers produced annually over the last five years.
He, however, said Petra would build production back towards 2 million carats over time, reaching 1.9m carats by 2019.
"It’s not a well known fact but Finsch has produced a number of large, special diamonds over its history and the recovery of significant large, high- value stones can substantially increase the total value of production in any one year,” he told delegates.
Dippenaar said on average, 27 diamonds larger than 50 carats had been recovered annually over the past four years at Finsch.
