Unbranded Vintage Silver Tone Spiral/Screw Brooch Pin Brilliant Blue Rhinestones Costume

Description: This eye-catching vintage pin features a striking spiral, wave, or screw-like design in a silver-tone metal setting. It is adorned with multiple, prong-set round blue rhinestones that catch the light. The piece measures approximately 2.5 inches (6.35 cm) in length, as indicated by the measuring tape image. It has a standard safety-clasp pin back. As is common with many vintage pieces, the brooch is unmarked (unsigned). This style is reminiscent of mid-century (1950s-1970s) costume jewelry.
