I found this crystal skull while digging through some old jewelry. I decided to make a ring of it. I used quite a few found objects on the ring. The back is silver from an erring I found smashed in the street in front of Fenway Park. I have had that smashed earring for about 20 years. Now it is part of this cool ring. All sterling silver with an Iolite bullet crown. The ring is a size 7.
