No, his logic is that the supply far out strips the demand but the supply is purposely suppressed. Lots of land out there but not much available when compared to the demand, especially land that is desirable, there is no comparison what so ever. The diamond supply is huge, the diamonds allowed on the market are few compared to the demand, which keeps the price artificially high. Dan Tucker is correct, you are not.
There is far too much money and profit to be made and no reason at all to upset the apple cart. The market in diamonds will not change appreciably in our lifetime, or our childrens.
