4ST401-F: Onyx Round FC 4mm is backordered and will ship as soon as it is back in stock.
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.
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.

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.
