Onyx Rings

Onyx rings in 10K and 14K yellow and white gold, plus sterling silver, set with black onyx and often accented with diamond or cubic zirconia. Styles include smooth cabochons, square and rectangle faces, grooved ovals, nugget shapes and designs with a cross or eagle.

Choose a plain onyx ring for a clean, dark look that works every day, or pick one with diamond accents for a little sparkle. Yellow gold gives strong contrast against the black stone, while white gold feels cooler and more modern. Browse yellow gold onyx jewelry, white gold onyx jewelry or all rings. A ring can be exchanged for another size within 30 days, and orders over $99 ship free.
