Vintage 1950s Concentric Circles Aquamarine Rhinestone andTassel Gold Tone Brooch Book Piece Costume Jewelry

Documented on page 231 of Marcia “Sparkles” Brown’s Unsigned Beauties of Costume Jewelry, this striking vintage 1950s brooch is a recognized book piece and an exceptional example of unsigned mid-century costume jewelry. Often described by collectors today as the “Concentric Circles” brooch, its sculptural gold-tone design features three overlapping circular motifs, each centered by a brilliant faceted aquamarine-color rhinestone. Three articulated chain tassels suspended below terminate in sleek pointed drops, combining strong geometric form with graceful movement.

The dimensional construction is particularly effective. Raised concentric circles create an architectural openwork design while the vivid blue-green rhinestones provide dramatic contrast against the warm gold-tone metal. Each of the three chain tassels hangs independently and moves freely beneath the brooch, giving the piece considerably more presence than a conventional stationary pin. Although unsigned, its appearance in a recognized costume jewelry reference provides valuable documentation for collectors and establishes the design firmly within 1950s vintage costume jewelry.

This brooch comes from my late uncle’s collection, assembled over more than fifty years of collecting exceptional vintage jewelry. It measures approximately [ADD MEASUREMENTS] and remains in very good vintage condition with light age-appropriate wear consistent with careful ownership. The pin assembly functions properly, the gold-tone finish retains its attractive vintage character, the aquamarine-color rhinestones remain bright, and all three articulated tassels move freely as designed. Please examine all photographs carefully, as they form an important part of the description and accurately represent its condition.

With its documented book-piece status, distinctive concentric-circle construction, aquamarine rhinestones and dramatic dangling tassels, this unusual 1950s brooch has strong crossover appeal to collectors of unsigned costume jewelry, vintage rhinestone brooches, Mid Century jewelry, geometric jewelry, tassel pins, book-piece jewelry and vintage statement accessories. Its inclusion in Unsigned Beauties of Costume Jewelry gives collectors an unusually useful published reference for an otherwise unmarked design.
