A blue composite turquoise with mother-of-pearl 18K yellow gold over sterling silver ring measuring approximately 0.24 inches long by 0.85 inches wide - the inlay band ring combining two natural shell and stone materials. Composite turquoise provides the blue-green; mother-of-pearl adds its characteristic iridescent shimmer. Together as inlay in warm gold, the two materials create an organically patterned band with visual interest that factory-made rings cannot achieve. Not sizeable.
