This is a vintage 1960s circular starburst brooch featuring a vibrant and contrasting combination of stones.

The piece is a gold-tone filigree setting with a multi-layered design. Its core is composed of eight long, light pink marquise-cut stones that form a striking star shape, each pointing inward toward a central, deep red round stone.

Accenting this starburst are smaller round stones in two colors: smaller deep-ruby-red rounds and some medium-sized pale-pink rounds, meticulously set into the gold metal filigree to fill the circular form.

The back of the brooch reveals an openwork gold-tone structure with a functional safety rollover clasp mechanism. This piece is considered an "unsigned beauty," as no maker's mark or signature is stamped onto the setting.
