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

String them into single-strand or layered necklaces where the round shape and consistent 6mm sizing make for even, satisfying spacing; they also work well as bold punctuation beads between metals or lighter stones in mixed-material bracelets.
