Joey Allen is a Navajo silversmith who makes fine rings with deep-stamped shanks and set with high-quality natural turquoise stones.
This is reminiscent of the ring that Keith Richards always wears. I recently saw another famous guitarist wearing a skull ring in a YouTube video, but I cannot now remember who it was. This ring was entirely sandcast from hand-carved molds. The shank was cast and then decorated with stampwork after being removed from the sandcast mold. The skull, of course, is a one-of-a-kind casting. Beautifully handmade!
Halmarked JA and stamped Sterling inside.
Skull: 1 1/8" x 3/4"
Width of shank in front: 1 1/4"
Width of shank in back: 3/8"
