Crysophase baroque clasp

The last time costume jewelry was very popular, the West Germans spent a lot of time reproducing stones in glass. This is one such example from the post-WWII era. This is green glass swirled with white with an irregular surface. With this vintage centerpiece you get both color and texture. The clasp is 18 mm across, 24 mm from ring to ring and 15 mm high. The centerpiece is set in a hand-made sterling silver box clasp. Available with one ring or three rings, please specify.
