Res, you are probably correct.
Of course, we have the conspiracy theororists who believe that DeBeers purposely crushed the sample (against the wishes of SNO) in large pieces (greater than 12.5mm) and then used a coarse set of sieves because they are only interested in large diamonds and can't be bothered with, what someone on SH called, material for sandpaper.
Then, I could dream up some other theory too. Look how many popular novels are available that are on the New York Times bestseller list.
That's it, that's how someone can get back all his losses. Write a bestseller featuring a conspiracy in the diamond mining industry. Now all we need is a good name. Hummmmm?
