A bit of gemology: onyx is a variety of chalcedony, a microcrystalline quartz from the same family as agate. Its name comes from the Greek onyx, "nail," in reference to the light and dark bands of certain stones. Its hardness of 6.5 to 7 on the Mohs scale makes it resistant for everyday wear. A perfectly uniform black is rare in its natural state.

Good to know: like the vast majority of black onyx on the market, these beads are natural chalcedony whose color has been obtained by dyeing, then fixed by heating. This practice, already described in antiquity, ensures a uniform and stable color.

In lithotherapy: black onyx is associated with the root chakra. It is credited with a role in protection and grounding, and is said to be conducive to concentration.
