i was at an antique store today and saw the larger open heart necklace. the guy said it was and he hadn't seen any paretti in years...which was fishy because tiffany's still sells it. maybe he's just not up on it. anyway. the font on tiffany and co was antique-y looking script instead of blocky. the porpotions of the heart looked right but the chain was obviously wrong (which isn't so important because i have thought about changing my chain too...its so thin). anyone know when they introduced the paretti line? i was under the impression it was only a couple years ago. and how about the font? have they ever changed the tiffany font? i'm thinking all this is fishy, but i don't know that much about older tiffany pieces either and if it's real, i'd like to go back and get it. thanks!
