Need a cross

I want to give my daughter a cross with diamonds for her coming of age. Where can I find something exclusive in this respect?

As for me, the cross is not a piece of jewelry and should not spend so much money on it! But everyone has their own fancies and so I can not impose my opinion on someone. If you want a cross with stones, then I recommend to go to the link http://formen.tforums.org/viewtopic.php?f=35&t=7799 I think it is very even not a bad option.
