These 4mm Black Onyx rounds are made from enhanced black onyx, delivering a consistently deep, even black that natural stone can vary on — great when you need reliable color across a full piece.

The enhanced treatment gives each bead a rich, uniform black with no distracting variation, so your finished work reads as intentional and cohesive.

What to make with them

At 4mm, these rounds are a natural fit for delicate stacking bracelets, knotted gemstone necklaces, and as spacers between larger focal stones in multi-strand designs — their small scale also makes them useful for bead weaving projects where a grounding dark tone anchors the palette.
