This 1960s "atomic' brooch has a distinct mid-century openwork design characterized by a series of interlocking gold-tone wire circles that form a swirling, floral-inspired motif. At its center is a prominent, faceted blue rhinestone (often referred to as blue sapphire or aqua-colored) securely held in an openwork crown-style setting featuring a series of prongs arranged in a starburst or sunburst pattern. It is surrounded by an open swirl circle or "atom" style floral motif with a radial geometric pattern. It has a standard brooch pin with a secure safety clasp.
This swirl pin measures 1.5" across and the blue sparkling center stone makes it pop. Retro jewelry like this often demonstrates superior workmanship and was made to last.
