Six-millimeter round, 8mm round, and 6x6mm trillion-shaped blended spiny oyster shell with composite turquoise oxidized sterling silver dangle earrings measuring approximately 1.84 inches long by 0.60 inches wide with push-back backings - the Southwest earring that combines three stone shapes and two natural materials in an oxidized setting. The three-shape arrangement creates visual variety along the dangle; the dark oxidized finish makes both the spiny oyster and turquoise colors appear more vivid by contrast.
