This is a vintage rhinestone brooch or pin with a form like a swirl or crest of a wave of 3 levels of round clear rhinestones.

The unmarked brooch or pin measures .5 inch deep by 1.5 inches high by 2 inches wide, was made in the USA in the 1940s.

An unusual form, I would call it a swirl, 3 level swirl, wave, cresting wave or curl.

original NOT reproduction

The elegant vintage rhinestone pin or brooch consists of round rhinestones, Rhodium plated metal and closes with a roll clasp.

The brooch is in very good used vintage condition with no stones missing. There are a few with minor, pale discoloration, which may only mean cleaning is needed.
