This bracelet is built around a centerpiece that features a bead crafted from 100 million year-old dinosaur bone found in the American West. Every bead, by the very nature of the extraordinary material, is unique in pattern and color. Flanked by sterling silver and frosted black onyx and with a comfortable and secure sterling clasp system. Whether you are in denim or business attire, the 'Gentis' wears beautifully and adds your own distinct style. Great on its own or layered with other piece.
