Faux coral clasp

During the height of the costume jewelry craze between the two World Wars, German artists were making amazing faux stones for that jewelry. This faux coral is one example, with black and white veining shooting through the coral coloring. This is a large piece and would make a statement on a necklace of bracelet. We offer it is two variations: a single strand perfect for necklaces or a three ring version set vertically to be used as a bracelet clasp or it would work beautifully as the centerpiece of a three strand bracelet.The centerpiece is bezel set in a hand-made sterling silver box clasp. The single strand is 47 mm from ring to ring and 26 mm wide. The 3 ring version is 37 mm from ring to ring and 35 mm high. Please specify.
