Black Onyx Gemstone Beads & Components
These are the semi-precious Black Onyx smooth, faceted, and carved beads we currently have in stock.

Black Onyx is a black, glossy, hard stone that actually is a black form of chalcedony. While "true onyx" has banded color layers, black onyx will be uniformly black.
