Strength, protection, grounding
What is Onyx?
Onyx is the black form of banded chalcedony, polished since Greco-Roman times into cameos and signets. Bead-grade onyx is a deep, even, satin black.
Meaning & symbolism
Onyx symbolizes self-mastery: composed strength, discretion, and steadiness under pressure. It is the quiet authority of the black stones.
How to wear & pair it
The backbone of men's designs and monochrome stacks — flawless with hematite, tiger's eye, or a single contrast stone. 8–10mm.
Care
Hard and easygoing: wipe clean. Its even black hides wear beautifully.
