The South African diamond beneficiation market is no longer globally competitive, says rough and polished diamonds and precious stones trading association World Federation of Diamond Bourses president Ernest Blom. He tells Mining Weekly that the local diamond beneficiation industry has "shrunk significantly" from its historical global peak 20 years ago. He emphasises that, while the local industry used to boast more than 4 500 diamond polishers at its peak, this number has shrunk to fewer than 300 diamond polishers.
