Amazing play of color natural Ethiopian Opal(.54ct, VVS, Ethiopia) hand set in a sterling silver ring. This Opal has more color then the picture can show. With every turn a rainbow of colors dance across the cabochon gemstone.  One of the world’s most coveted gemstones, opal’s name evolved from the Roman opalus which was derived from the Greek opallios, meaning “to see a change of color.” The Greek word was a modification of the ancient Indian Sanskrit name for opal, upala.
