What does natural onyx look like?
Natural onyx is a banded variety of the silicate mineral quartz, composed of tubular microcrystalline fibers. It typically appears as a black and white, striped or mottled stone, being a cross between agate and chalcedony.
It has a waxy or glass-like luster and is often translucent, though some specimens exhibit greater opacity due to a higher content of impurities. Natural onyx generally consists of white parallel bands that are several millimeters wide and which tend to display a slightly undulating surface across their length.
The thickness of these bands varies from one specimen to another, as does the width. Along its length, the bands may swell or thin, and one turn may give way to another of a different color, creating an interesting pattern.
When observed in its natural state, natural onyx may resemble a mosaic of white, black and grey blocks, although once worked and polished, this visual texture is completely altered.
