One copper electroformed Rare Snakeskin Agate Crescent Moon complete on an 18” soldered gunmetal chain. Gunmetal patina coffin. 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! Moons measure approximately 1.0" x 0.5". Size, shape, color and pattern may vary as no two stones are alike.
