What are Onyx Beads?

Onyx beads are cut from onyx, a variety of chalcedony — microcrystalline quartz (Mohs hardness about 6.5–7) — with straight, parallel bands. The best-known form is solid 'black onyx,' though onyx naturally occurs banded in black and white and other colors. Much commercial black onyx is natural grey agate that has been dyed solid black, a stable and long-accepted treatment that produces the deep, even color jewelers prize.

Types of Onyx Beads

Black onyx — the classic solid black, usually dyed for an even color.
Banded onyx — natural black-and-white parallel bands.
Sardonyx — reddish-brown and white banded onyx.
Green and red onyx — dyed color variations.
Matte (frosted) black onyx — a popular unpolished finish.

Onyx Beads meaning & symbolism

Onyx is traditionally associated with strength, protection, grounding, and self-discipline — a stone for focus and steadiness, and a popular choice in men's and unisex jewelry.

History & cultural significance

Onyx has been carved since antiquity — into cameos, seals, and beads across Egypt, Greece, and Rome, where its layered bands were ideal for relief carving. Black onyx has long featured in mourning jewelry and remains a timeless classic.
