What's Black and White and very dramatic? Other than a neurotic zebra, these earrings! These long cluster earrings feature a spiral design of 4mm Black Onyx and Snow Jade beads that have been spiral wrapped with Argentium (anti-tarnish) Sterling Silver wire. Each bead hangs from a length of Sterling chain. The length is 2-1/4 inches from the top of the Sterling Silver earwires.
