I'm considering getting my second Tiffany's necklace - I already have the oval tag Return To Tiffany's necklace that I LOVE but I want something a bit more 'delicate'. Please help me decide between these two: [click pic to enlarge] $100 [very good price!] $175 [only $75 more, and it's a lock that can be removed] I like the idea that the second one's pendant can be removed so I can attach it to a different chain... however, the first one's price is more appealing as I'll most likely be paying for all, if not - most, of it by myself. Opinions appreciated! Thanks!
