Onyx is a variety of cryptocrystalline quartz in which the forming bands are parallel and regular.

Its appearance is most striking when the bands are of a sharply contrasting color. Onyx, along with alabaster and lapis lazuli is considered a semi-precious stone. In ancient times it was used for the creation of jewelry, vases and other ornaments.

Onyx is a calcareous stone and prone to etching and staining from acids such as ketchup, lemons, alcohol, and household cleaners. Great care is needed to maintain the natural beauty of this stone. Similar to limestone, onyx is a softer stone best placed where it won't be used or abused on a day to day basis. It is porous and needs to be sealed. Otherwise, it will absorb water and liquids easily which tend to stain the stone. Once a stain is absorbed into onyx, it is extremely hard to remove.

Onyx marble is most often used as a fireplace surround, bar top, or as a small island because it transmits light.

Similar to marble, onyx can be finished with a polished surface. This is a glossy and reflective surface finish which deepens the color and contrasts within the stone. It can also be finished to a honed surface finish which is a matte like low sheen finish. It's not reflective and shiny like a polished finish. Consult your fabricator/installer if you have another surface finish in mind.
