It's a bit of a combination for me. I have some beautiful pieces from my ex-fiance (not an e-ring though, I didn't want one he bought me a painting instead) that honestly just make me sad to wear, so I don't know if I will ever actually wear those pieces again.
Then there are lovely commemorative gifts from my mother - 21st and 25th birthdays, graduation from law school. I have loved receiving pieces as gifts, but always have been involved in the choice as I have particular tastes and my mother and I agree, there is nothing so sad as a gift that you never wear or wear out of obligation!
Then there are the pieces I bought for myself - my Cartier TT tank francais being a particular favourite! Also my white gold channel set baguette diamond ring, a gift to myself for admission to the court roll.
I guess it's a combination for most people...
