This ring, made of solid 18-carat eco gold, features a beautiful black opal from the world-famous mines in Lightning Ridge, Australia. A truly extraordinary black opal whose play of colors is reminiscent of the open sea. Especially the variety of different shades of blue and the overwhelming green sparkle of the opal make this ring a remarkable eye-catcher that is second to none! We have paired this unique gemstone with six sparkling salt & pepper diamonds, which were meticulously hand-set into the ring.
