You may be right; I'll have to look into it for myself. I am for free markets, but I had read, and I will need to confirm if this is still true, that diamonds are plentiful, so the raw stock before cutting and them should be cheaper than current market price due to keeping them in stores to maintain an inflated price. Whether that's De Beers acting alone with its market share as you cited, or two or three other companies colluding on this scheme to keep an inflated market value or not, I need to confirm.
