I hate to say it, but as a jewelry designer, those Pandora bracelets just make me cringe. That being said, they are quite pricey. Make sure it's something she'd like before you pay the money. My cousin's husband bought her one and she absolutely hates it. It's completely not her style. Plus, she's a very active person and is always having to take it off because it's so heavy and jangly. She can't say anything because he's SO proud and thinks he picked a great gift and keeps buying her new beads for it. She doesn't want to hurt his feelings. It's sad because he spent a lot of money on it.
I agree with prhoshay - always nice to pick out your own. Costume jewelry is one thing, but with fine jewelry, I'd want to make the choice for myself. If it's something she's going to have for a long time, I'd want to be sure that it's exactly what she wants.
