This lovely vintage Swarovski crystal centerpiece would work with almost any necklace. The timeless beauty of Swarovski is unparalleled. This cabochon is most similar to the style 4675. The centerpiece is vintage, but the clasp was made recently. Each clasp is a hand made to my specifications using pieces from my vintage glass collection. The Swarovski piece is bezel set in a hand-made sterling silver box clasp. These clasps are made by some of the finest silversmiths in the world who work deep in the hidden recesses of the Grand Bazaar in Istanbul. The centerpiece is 18 mm square. The clasp is 31 mm from ring to ring. It is 20 mm wide and 10 mm high.
