I am having the same dilema. However, the one with the diamond heart sparkles way more and I feel I'll regret not getting myself the more luxurious one.....though it is a $255 money diffence. On the other hand, owning a lot of DY pieces, sterling silver shouldn't cost that much. But I guess beauty is in the eyes of the beholder.
I will most likely get the diamond one.
Good luck! You'll probably come to the same conclusion as me. :okay:
