Art Deco 10K White Gold Black Onyx Ring

A striking Art Deco ring crafted in 10K white gold and set with a black onyx centerpiece. The sleek, polished onyx creates a dramatic contrast against the bright white gold setting, while engraved detailing along the shoulders adds the crisp geometry and architectural character associated with the Art Deco period.

The stone is secured by decorative corner prongs that add another layer of period detail without distracting from the bold simplicity of the design. With its clean lines, monochromatic palette, and graphic presence, this is an exceptionally wearable example of Deco-era style.

Why We Love It

We love the contrast in this piece. The deep, glossy black onyx against the engraved white gold feels unmistakably Art Deco—bold, geometric, and sophisticated without being overly ornate. The hand-finished shoulder detailing gives it the character of an antique piece, while the streamlined design makes it remarkably easy to wear today. It has just enough presence to stand beautifully on its own, but it would also make an incredible addition to an antique ring stack.

Condition

This ring is in good vintage condition. The black onyx remains smooth, glossy, and free of major chips or cracks, showing only light surface wear consistent with age. The 10K white gold setting retains its structure and detail, with crisp engraving still clearly visible along the shoulders. The corner prongs are secure and intact, holding the stone firmly in place. Light patina is present in the recessed areas, enhancing the antique character of the piece. Overall, it presents beautifully and is ready for wear.
