With its inner fire, the opal has an almost other-worldly quality that makes it unique among gemstones. Opals boast a dramatic display of radiant colors. Most of the world’s opals hail from Australia, but they can also be found in Western Hemisphere countries like Mexico. Consider flashing an opal ring or a glamorous pair of opal earrings. A stunning opal necklace can add elegance to your everyday look.
