These 6mm black onyx rounds are enhanced natural stone — solid, weighty, and deeply black in a way that glass just doesn't replicate. Makers reach for them when a piece needs genuine presence and a little gravitas.
The enhanced finish gives the surface a smooth, uniform black with a subtle polish — consistent enough for clean, professional-looking strands.

What to make with them

Description
Onyx, a banded variety of the quartz family, is mined in Brazil, India, Madagascar, U.S.A and Uruguay. The only difference between onyx and other banded agates is that the stripes of onyx are even and uniform. Black onyx's uniform black color is achieved by dyeing and or by heat treating. The name Onyx is a Greek word meaning claw or fingernail, as it was once believed that onyx was created from the goddess Venus's fingernail clippings. Onyx and Sardonyx are essentially the same stone: onyx will have a black base, and sardonyx has a brown base.
