there is less than 1% of this diamonds in circulation.
How could he prove that number anyways?! Or how could we disprove it?! he doesnt know about EVERY diamond transaction going on does he? Think about it. And even if people who wear diamonds dont by the album, he's shedding light on the issue, and getting people talking about it! Look at us, none of us have got the the album but we are talking about it now!
As some dude said.. "I feel sorry for your mother" lol
