Word has spread all over the personal finance blogosphere about the class action settlement against DeBeers. If you live in the USA and purchased any diamond jewelry (even if it's mixed stones) or loose diamonds from January 1, 1994-March 31, 2006, for personal use or gift, then you might want to check it out.
We just barely made it under the wire. Greg bought my engagement ring in March of 2006. My friend that got engaged a couple of months later missed the window.
We filed our claim tonight and the form was ridiculously easy. You need the purchase price of the jewelry and may need some details about the stone (I didn't, our claim was small) but you don't have to automatically send in documentation if it's under $10,000. They do reserve the right to request it later so it wouldn't hurt to have it. You can either file online or on paper. The deadline is May 19, 2008.
They can't determine how much you might get because it depends on the number of claims filed, and if the payout is less than $10 they won't send you anything (administrative costs and all). But basically if you spent over $100 or so, it's may be worth a shot. I figure if we get $15 back, then we're $15 closer to paying off the mortgage than we were before. Or it's an extra dinner at McAlisters. Either way, it would be worth the 8 minutes it took to fill out the form online.
