Antwerp World Diamond Trade Center with a yearly turnover of more than 56 billion US $ explore the return on investment (ROI) in Gems: Rough Diamond prices increases continuously since 1949.
DeBeers Consolidated Mines Ltd. could develop a safe structure
to guarantee a continuous increment of prices, as it is already
the whole last century: two controlled companies, the Diamond
Producers Association (DPA) and the Central Selling Organisation
(CSO), respectively extract and sell a quantity of diamonds
according to the different market situation.
This is why there is no imaginable reason for which this
continuity can be stopped in the future.
