Sure some girls may pawn off or sell some diamonds that they have received, but I think most of us keep them forever. You discard a box of chocolates, and a vase of roses only lasts so long, bu diamonds last much longer. I have diamonds from years ago, my diamonds have outlasted many relationships, and I keep them as treasured memories.
I love diamonds too! especially in white gold or platinum. Heck, I even love diamonds in silver!
