Onyx for Auction - Ross's Auctioneers & Valuers
Onyx Like agate, onyx is a type of chalcedony (quartz) that is most commonly found in banded shades of black. Onyx can also be found as white, red, black and brown and, in its black form, is the most common and inexpensive black gemstone available. 

Because of its layered nature, onyx is often carved to create intaglios and cameos, to create an effective contrast between the background and foreground.
