Onyx is known for its solid, deep black color, though it can also appear with fine parallel bands. Its smooth, uniform surface has made it a popular choice for both classic and contemporary jewelry designs.
What Is Onyx?
Onyx is a banded form of chalcedony, closely related to agate. Where agate typically shows curved, irregular bands, onyx forms with straight, parallel bands — often so fine and consistent in color that the stone reads as a solid, uniform black. It takes a smooth, glossy polish well.
The Traditional Meaning of Onyx
Onyx’s deep, solid color has traditionally linked it to strength and protection across several cultures. It has also been carved into seals and ornamental objects since ancient times.
These associations are rooted in tradition and personal meaning, not scientific claims — chosen for their story and their beauty, not as a promise of effect.
How to Choose Onyx Jewelry
Onyx’s uniform black tone makes it easy to pair with nearly any metal or gemstone combination. Look for a smooth, even polish with no visible cracks or dull patches, which is a good sign of a well-finished piece.
Caring for Onyx
Onyx is a durable stone suited to daily wear. Clean it with a soft cloth, and avoid harsh chemicals, which can dull its polished surface over time.
