Mine, would be something on the feminine side. Metal though, with a screw down clasp. It would have my birthstone on it. I don't need nor want anything bold. It's not me. I like subtal things. Thin wire collar with a special print and several small saphires around the collar. That's me. Just thought of something....I think I would love to have my Master's birthstone as the center stone. Right in front for everyone to see.
