A death's head appears squashed to fit on the 22k band. (In the biz, we call these "pumpkin head rings".) In the 17th and 18th centuries these very rare jewels were used as reminders that death comes for us all. Rarer still: there is no inscription inside.
MATERIALS: 22k gold (tests)
AGE: c. 1700
SIZE: size 9, resizing possible but not recommended. 4mm shank.
