This mid-century brooch centers a large faceted blue glass stone set into an open-back gold-tone frame. Surrounding it is a ring of smaller rhinestones arranged in a raised filigree pattern. The pin uses an early C-clasp, which helps date it to the mid-1950s.
The overall construction and color palette suggest it may have come from Regency or an early Juliana line, both of which were known for hand-set stones and dimensional metalwork. Pieces like this were typically sold in department store sets during the post-war boom in costume jewelry.
The brass has aged to a mellow tone, and the back shows the kind of careful openwork you usually only see on higher-grade costume pieces of the period.
