Week 12-Vernal Equinox

I suppose I could make up some story about how this fits the theme of vernal equinox but I'm not that creative. Actually, I'm fascinated with old keys and this is just something I wanted to make for myself to wear around on a long chain. It has plenty of imperfections but I'm sure as heck not doing it over. :D It's about two inches long and a little over an inch wide. The beads are teeny tanzanites.
