Is it really true (I'm not doubtful, just shocked) that the jeweller can tell you what country the diamond came from unless that country is in a particular continent?
Because of the 'blood diamond' controversy, the diamonds get mixed up together, sold around, exported, smuggled, etc. There's no way to track them.
Canadian ice diamonds, on the other hand, are all laser-engraved with a serial number, making it possible to verify each diamond's authenticity and source. According to the jeweller I spoke to, the only guarantee she could make is 'Canadian' or 'not Canadian'; she couldn't even guarantee me African, Russian, etc.
She did, of course, offer to sell me a ring with 'who knows' diamonds and then remove them and put Canadian diamonds in, but at that point I'm paying for 'who knows' and Canadian diamonds, which seemed a little idiotic.
