Yes, I'm not the type to wear a lot of accessories to make myself look pretty. That doesn't an that when I see shiny, pretty things like a sterling silver necklace, I would just ignore it and not even pause for a while to admire its beauty. I'm a sucker for those kinds of girly things too! :)
I think every girl secretly wants to given pretty things as gifts, as much as the tomboy types would likely disagree. I don't think we can help it - to be attracted to shiny and pretty jewelry. It's kinda like your first instinct, when presented with these things, that you'd go 'ooh-ing' and 'aah-ing' over them.
So, if you're to be given something like them as gifts, then enjoy it! And don't bother denying your glee!
