I love jewelry of just about any type.
I wear a lot of silver and white gold. My favorite stone is my birthstone, opal, although its not the only stone I like.
Probably my dream piece would be a custom piece, black opal, set in white gold... Something flowy and abstract, pendant, ring and earrings, maybe a cuff bracelet, too. I tend to avoid "classic" jewelry looks, and really prefer something custom and unique. I have a great jeweler who knows what I like and has really come through for me more than once. I'm saving up to commission a set like I've described. Someday, maybe. *grins*
