These 10mm black onyx rounds are a go-to for makers who want a bold, grounded stone with real presence. Enhanced black onyx delivers that deep, consistent color that's hard to achieve in a natural stone at this size.
The enhanced finish gives each bead a rich, uniform black — dense and opaque with a smooth surface that catches light cleanly.

What to make with them
At 10mm, these rounds are substantial enough to anchor a statement necklace or stand alone in a single-strand design; they also work beautifully spaced between metal findings or smaller accent beads in wrap bracelets and mala-style stringing projects.
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.
