"The fall in the price of platinum in 1930 was attributed to the increased production of South Africa at a price so far below what the metal could be produced for in other sections that it was proposed by producers to form a combination to maintain a stable price, as has been the practice of the diamond producers' syndicate."
In South Africa, the ore price fell to £ 7. (6/1930: USD$ 33.88)
