Blue onyx is a dyed stone, that can have fine bands or none (due to the nature of onyx). Onyx has been dyed since ancient times - to improve the depth of color, and especially to achieve the much-desired black hue. The treatment usually involves soaking chalcedony in a sugar solution, which penetrates the stone through the fractures present on the surface. Pretty cool, huh!
