This is made from a vintage Towle Sterling silver spoon, made into a mermaid tail pendant. The pattern is called "Paul Revere" and is from 1906.
The pendant is 2" wide and almost 1 7/8" tall.
It is harder to see but is marked STERLING on the inside if the loop from the original spoon manufacturer.
These Mermaid tail pendants from spoons are one of a kind, designed and handmade by me.
