Christo Wiese, South Africa’s richest man, sees opportunities to consolidate diamond operations in the region after buying a stake in a Cape Town-based miner of the precious stones. Wiese, 74, has always been “fascinated’’ by diamonds and saw good value in Trans Hex Group Ltd., he said in an interview in Cape Town last week. “There are opportunities for consolidating diamond operations in southern Africa,’’ he said. “Obviously we will look at growing the business as much as we can.’’
