Vintage Unsigned Gold Tone Brooch Opalescent Jelly Navette AB Rhinestone Pin

A striking mid-century spray brooch featuring open-back “jelly opal” navette glass stones that glow beautifully with light behind them — a hallmark of quality vintage glass work. Branches are accented with faceted smoky rhinestones and a single sparkling AB (aurora borealis) round stone as a focal point. Gold-tone base metal setting, prong-set stones throughout. Trombone-style pin clasp on reverse, consistent with 1950s–60s manufacture. Unsigned — no maker’s mark found after close inspection, but the open-back setting and stone quality suggest better costume-house production. Measures approximately 2″ x 1.5″
