3D Printed Jewelry

This is a little side project I made for my girlfriend. I sculpted three pieces in ZBrush, had them 3D printed in wax and cast in brass by Shapeways. First I made earrings in the shape of a female mask, then a tiny mouse that would hang from a keychain ring by it's tail and finally another keychain pendant in the shape of a tiny hand making the thumbs up gesture (or thumbs down, depending on how you look at it, I suppose).
I'm including a piece of rough concept art I did for the ear rings here.
