Hmm, thats a good point, but in the end I have to try on and compare both to be 100% sure, before buying oneLove Cartier but their diamond wasn't as sparkly or noticeable as the Tiffany's, probably bc their chain was sturdier. I prefer the Tiffany, dainty chain, floaty diamond was the whole point of the look. W the Cartier when I tred it on, it had too much chain. Try it on and take a pic f it you'll c what I mean...but buy what you like in the end.
