Onyx refers to the parallel banded variety of the silicate mineral chalcedony. Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands: agate has curved bands and onyx has parallel bands. The colours of its bands range from black to almost every colour. Commonly, specimens of onyx contain bands of black and/or white.
