C form, just under 2 1/4” inside (2.16”). Tapering slightly from the middle to the stylized serpent head terminals. The body's high relief is decorated in a series of alternating square and oval forms with markings in lattice and reeded patterns. The markings are deep and distinct but not symmetrical and of no evident pattern. Likely a code with spiritual significance known to the owner, now lost. Professionally refurbished with the 24karat gold surface restored for modern wear. Jewelry gift boxed with certificate of authenticity.
