Anatomical Skull Ring Half Jaw (SIA) Sterling Silver

The SIA (Standard Issue Anatomical) is a half-jaw skull ring cast in solid .925 sterling silver. Where other skull rings express ornamentation, the SIA relies entirely on form — precise anatomical structure, clean surface planes, and a half-jaw silhouette that exposes the underlying bone geometry without embellishment.

Cast in solid .925 sterling silver and finished by hand in our California studio.
