Copper electroformed gunmetal patina, Rare Snakeskin Agate Heart on an soldered 18″ gunmetal chain. This material is from Madura Island, Indonesia. Although it looks like snakeskin, it’s actually fossilized palate of ancient wrasse. Wrasse are a family of brightly colored marine fish. These hearts are small but mighty, truly rare and unique! Hearts measure approximately 1.0″ x 0.75″. Size, shape, color and pattern may vary as no two stones are alike.
