Most Tweens love jewelry. I bought a beautiful initial sterling silver necklace for my 13 year old cousin for her birthday. She has EVERYTHING she could ever ask for but absolutely loved that gift. Her mother bought her a genuine diamond necklace for her birthday,but she always wears her M instead. In case anyone is interested, I purchased the M initial from Buyz.com and it cost $12.00, or you can bid on them on Bidz.com if they list the initial you need that is. The only drawback is the shipping is expensive. If you spend $60.00, shipping is free....so I bought the same necklaces for all the Tweens in my family. Here is a link to check it out.
