A Note on Color:

Photography is captured under controlled lighting to represent this piece as accurately as possible. Each sapphire color shifts with the angle of light and view, and colors may read slightly differently depending on your light source, screen calibration, and brightness.

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. 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. Avoid chlorine, harsh chemicals, and prolonged chemical exposure. 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 to prevent tangling and protect the sapphire stations, diamond stations, hinges, clasp, and Bismarck chain. Annual inspection recommended — verify all sapphire and diamond prong settings, all 12 hinges including the chain connection, station-link integrity, clasp security, and chain condition at each inspection.
