Deep purple is flecked with silver and white to make a lovely marble effect. The clasp would go well with dark amethyst or be an accent to pop a strand of pearls. Happy people wear purple, so if you are happy, this clasp will go with whatever you are wearing! The vintage Czechoslovakian glass centerpiece is bezel set in a hand-made sterling silver box clasp. The clasp is 28 mm from ring to ring and 15 mm high.
