Onyx Jewelry: The Dark Elegance of the Black Stone
In a world of pastel gemstones and sparkling diamonds, black onyx stands out with its dark, uncompromising elegance. Matte or highly polished, with a depth that swallows light – black onyx is the gemstone for those who like strong statements, love contrasts, and don't hide. In this comprehensive guide, you'll learn everything about onyx jewelry: its mineralogy, history, symbolic power, and the most beautiful modern designs.
What is Onyx?
Onyx is a variety of banded chalcedony (microcrystalline quartz, SiO₂) with parallel, alternating color layers. True onyx has white and black layers – however, what is offered as "black onyx" in the trade is usually uniformly black chalcedony or dyed agate. This is an accepted practice in the jewelry industry and does not alter the stone's beauty.
With a hardness of 7 on the Mohs scale, onyx is well suited for all types of jewelry, especially rings and bracelets. It can be polished to an exceptionally deep, even black that is unlike any other stone.
The History of Onyx
Onyx has a fascinating yet ambiguous history – it has been both loved and feared:
- Ancient Rome: Onyx was used for cameos (relief carvings) and signet rings. At the same time, it was associated with misfortune and evil spirits – it was believed that onyx brought nightmares and depression.
- Arab World (Medieval): In Arabic, onyx was called "el jaza" (sorrow) and was believed to cause discord and sadness. Pregnant women were warned against it.
- India: Onyx was used as a protective stone against the evil eye and negative influences.
- Victorian Mourning Jewelry: Black stones, including onyx and jet, were extensively used for mourning jewelry in the 19th century. Especially after the death of Prince Albert in 1861, Queen Victoria initiated decades of black mourning fashion.
- Art Deco (1920s–1930s): Onyx experienced its most brilliant heyday in Art Deco – the characteristic black and white contrasts and geometric designs of the era made onyx the ideal partner for white gold and diamonds.
Onyx Meaning and Symbolic Properties
Despite its historically ambiguous reputations, onyx has gained a clear positive meaning in modern spiritual practice:
- Strength and Willpower: Onyx is said to give the wearer inner strength and promote determination and perseverance in difficult times.
- Protection: As a dark stone, onyx absorbs negative energies before they reach the wearer. It is considered one of the most powerful protective stones.
- Grounding: Associated with the root chakra, black onyx is believed to ground, center, and stabilize the wearer.
- Decision-making aid: Onyx is said to help with important decisions by clearing the mind and eliminating distractions.
- Self-control: It is said to temper impulsive behavior and contribute to considered, deliberate action.
Onyx Jewelry Styles

The most classic onyx jewelry of all. Black onyx as a flat stone in a wide gold ring is timelessly masculine and elegant. Signet rings have been used for personal engravings since ancient times – an onyx signet ring with initials is still a statement piece for men and women today.

Black onyx combined with yellow gold or white gold is one of the most timeless jewelry contrasts. Art Deco-inspired designs with onyx rectangles in white gold are strongly in revival in 2026/2027.

How to Care for Onyx
Onyx with a hardness of 7 is robust for everyday wear, but a few care tips will help maintain its shine:
- Lukewarm water + mild dish soap + soft brush
- No ultrasound for dyed onyx – color may detach
- Polish with a soft polishing cloth after cleaning to maintain high gloss
- Store separately – even onyx can be scratched by diamonds
- Protect from strong impacts – despite its hardness, onyx can chip with strong impacts
