Oval Australian Opal & Diamond Necklace

Nine oval Australian opals totaling 5.40ct alternate with eight round brilliant diamonds along a flexible, flat Bismarck mesh chain. The opals graduate in size, with deeper, more domed stones at the center tapering to flatter stones toward each end, and show shifting flashes of red, green, blue, and yellow. Individually hinged stations let the necklace move with the wearer. Crafted with natural Australian opals, natural diamonds, and solid 14k yellow gold — wearable art that holds its value.

A Note on Color:

Photography is captured under controlled lighting to represent this piece as accurately as possible. Australian opal play-of-color shifts with the angle of light and view — individual stones vary in dominant hue, and colors may read slightly differently depending on your screen's calibration and light source.

Care:

Your jewelry is a lifetime investment and a work of art — treat it with the care it deserves. Remove before sleeping, swimming, bathing, showering, or any prolonged water exposure. Avoid chlorine, harsh chemicals, and prolonged chemical exposure. Never apply lotions, creams, hairspray, perfume, or cosmetics while wearing — always put on last. Avoid prolonged exposure to perspiration. Avoid impact and abrasive surfaces. Keep away from hot water, direct sunlight, and sudden temperature changes. Never use ultrasonic or steam cleaners. Wipe gently after each wear with a soft, dry cloth dampened with plain water only — do not soak or rinse under hot water or running water. Store separately in a soft pouch away from harder jewelry. Annual inspection recommended — verify the box clasp and safety catch, all nine opal settings, all eight diamond settings, independent hinge integrity, and Bismarck chain integrity at each inspection.
