De Beers to hold sight next week without SA rough diamonds – report

16 june 2017
De Beers is expected to hold its sightholder sales next week at the Diamond Trading Company Botswana (DTCB) in Gaborone without rough diamonds from neighbouring South Africa.
South Africa's minerals minister, Mosebenzi Zwane, had been refusing to grant an exemption to De Beers Consolidated Mines (DBCM) to export diamonds to Botswana for aggregation.
DBCM had since approached the local courts to force the minister change his position.
The Patriot newspaper quoted Botswana Chamber of Mines chief executive, Charles Siwawa, as saying that it was surprising that such a decision with far reaching implications on the relationship between the two neighbouring countries had been made by the individual minister.
"The decision could affect bi-lateral relations between the neighbours. It should not have been unilateral at ministerial level,” he said.
“One would expect that it would be reached after both governments engage at a high level where one would forewarn the other to make necessary preparations going forward."
Siwawa said although blocking supply from South Africa for aggregation in Botswana would not stop operations at DTCB, although it would disrupt the diamond mix in the process.
Diamonds produced by De Beers in South Africa, Botswana, Namibia and Canada were aggregated in Gaborone like they used to be in London.
Once the aggregation process was complete, rough diamonds of higher value were then re-imported back to the producing countries, South Africa included, for cutting and polishing.
About 40 percent of diamonds mined in South Africa by De Beers were allocated to local diamond cutters and polishers.
