This unique two strand clasp most likely dates from the 1960s. It is a clover shape with a lightly textured surface, roped edging and multi-color rhinestone accents in garnet, emerald and blue. In the center is a small space for a bead or cabochon. This clasp is in perfect, unused vintage condition with solid constructed weight to it. It measures 20mm x 30mm. I have a limited supply of these available.
