Tzoffey's 1818, the Israeli-French auction house is adding a 600+-carat rough diamond to its tender during the March 9-13 International Rough Diamond Week (IRDW). The goods to be tendered are directly from the source.

The IRDW is slated at the Israel Diamond Exchange.

This 600+ carat rough diamond was sourced from an African mine and according to Tzoffey's president Avner Sofiov, the stone is ‘cleavable which, once planned and cut, will render a number of larger polished diamonds’.

"I am very excited to include such a large stone in the Tzoffey's tender in March," Sofiov said. "The International Rough Diamond Week is a joint project of the entire Israeli diamond industry to boost our country's position as an international rough diamond trading hub.” He noted that more than 200 participants had scheduled viewings for the Tzoffey's tender alone.

IDE Deputy President Arnon Juwal, who heads the IRDW organizing committee, around 350 diamantaires - from Israel, India, Belgium and the USA - will view the rough diamonds of the IDE Tender Facility, Fusion/I Hennig Tenders, De Beers Auction Sales, Rio Tinto and Tzoffey's.
