Dd is thirteen next week, I would like to get a piece of jewellry for her - she doesn't have her ears pierced and would prefer a necklace as opposed to a bracelet/bangle type thing - I'd just like her to have something timeless/classy but not horrible ostentatious to remember her teenage years by - any ideas? i don't have the faintest - don't want to go to ratners ;) want to spend around £50-ish.
