How the heck do we know for sure? They all pass thru Amsterdam or Brussels..

OTOH, why aren't Russian diamonds considered to be "blood diamonds" too? The stinking Commies had blood dripping from their collective hands for generations.
All the conflict diamonds invariably come from former European colonies that were left with the basis for a fairly decent society. Most became corrupt basket cases. One country, Sierra Leone, that was able to beat back the sadistic terrorists, RUF, iirc, made the mistake of abandoning a military dictatorship too soon, and electing some quack UN type. The RUF immediately went on the offensive, and resumed killing, raping, maiming, and enslaving people. That's not to mention the absolute corruption of adolescents who probably will never be able to be integrated into any civilization.
Anyway, back to Brussels. I think it was Liberia that was doing about $10M a year in diamonds, and with all the conflicts, it shot up into several billion, since Liberia was the laundering operation for hiding the true source of "blood diamonds". All those old trading and smuggling trails from years gone by. Wink-wink, nudge-nudge.
