These earrings are made with Maine Tourmaline Composite cabochons. The cabochons are made using a composite with tiny fragments of black Maine Tourmaline giving the depth, dimension and shimmering appearance. The stones are encased in peyote stitch bezels and the embroidery surrounds use carefully matched beads to mimic the swirls and patterns of the stones. The ear wires are niobium which is known for being non-allergenic. The earrings measure approximately 1 & 1/2 inches long.
