These are AA-grade Black Onyx hand polished stones from Ancash, Peru, sold by the piece or by the pound. Black Onyx is a uniformly black chalcedony, the solid-color cousin of banded agate. Each piece runs 1-1.50 inches at Mohs 6.5-7, bought directly at the source. A favorite protection stone for pockets.
Black onyx is deep, uniform black with a glassy polish when it's cut right. Most market material has been dyed for consistent color, so if the seller doesn't mention that, assume it.
Our tumbled stones are sourced from Ancash, Peru. Worth knowing: a lot of the black onyx on the market is dyed. What we carry is natural and untreated.
The Romans carved it into cameos, and most commercial black onyx on the market has been dyed for consistent color since naturally solid-black material is rare.
In crystal traditions, black onyx is often associated with a sense of groundedness when things feel uncertain, staying connected to your body and the moment, and settling into who you already are. It's traditionally linked to the root chakra. If that resonates, set one on the floor near where you sit to read or work. Work with it the way that fits your own practice.
These are traditional associations drawn from historical practice. This stone is not a substitute for medical or mental health care.
