Black Onyx Stone Properties and Silver Settings
Black onyx has served as a protective stone across cultures for thousands of years. Ancient Romans carved it into seals and signet rings, while Greek artisans shaped it into cameos. The stone's solid black color comes from carbon and iron inclusions during formation. Unlike banded agates, pure onyx displays consistent coloring throughout each piece. Our sterling silver settings complement the stone's dark surface with polished and oxidized finishes. Each piece uses .925 silver, the standard for quality sterling that contains 92.5% pure silver alloyed with copper for durability. The metal's cool tone creates clear contrast against onyx's warm-absorbing black surface. We have shipped onyx jewelry with free delivery across the United States since 2005. Browse the collection to find pendants, statement rings, and earrings featuring natural onyx stones in weights and cuts that match your preferences.Is pure onyx the same as black onyx?
Pure onyx and black onyx refer to the same stone when describing solid black chalcedony without banding. The term pure indicates consistent color throughout rather than the striped patterns found in banded onyx varieties.
How should I care for onyx jewelry?
Clean onyx with mild soap and warm water using a soft cloth. Avoid ultrasonic cleaners and harsh chemicals. Store pieces separately to prevent scratching from harder gemstones like diamonds or sapphires.
Where does natural onyx come from?
Major onyx deposits exist in Brazil, India, Uruguay, and Madagascar. The stone forms in gas cavities within volcanic lava flows, where silica-rich solutions slowly crystallize over thousands of years.
