What a fab haul!
I love that Tookalon necklace - have considered buying it, but know I wouldn't wear it because (unfortunately) it wouldn't suit my style.
Regarding the ring, I think it would look a bit daft to wear a teeny little ring with a huge necklace and bracelet - if you're going to wear a ring at all, it needs to be in proportion. My advice is to keep it - you never know, you may be converted!
