[quote=pri_dk]Some trivia:

The diamond engagement ring “tradition” really isn’t that old. And of course if was created by corporate marketing.

If you are over 40 or so, there’s a good chance your grandmother did not get one because she didn’t know she was supposed to want one.

It’s pretty well known that DeBeers came up with the diamond engagement ring marketing tool – then later came up with the idea that it should be several months salary!!!! Diamonds are probably the most manipulated market out there. DeBeers holds back diamond supply to raise the price.
