Onyx Formation and Uses

Composed chiefly from quarts minerals, onyx can refer to a fairly broad range of mineral structures in this industry. Traditionally onyx is a term reserved for a particular type of black agate material usually with bands of white running through it. Today the term is more general, and can refer to a material that is semi-translucent regardless of it coloration, vein type, hardness, or specific mineral composition. Because of the broadening definition (considered to be inaccurate in a geological sense) of this material category, onyx materials can vary in hardness and suceptability to acidic environments. In large, the industry recognizes onyx as a rock materials with a natural translucency. Due to this distinction it is often set on metal frameworks and backlit to achieve a dramatic look for ceiling lighting fixtures, shower walls, and even unique light-up countertops. Onyx can be used in a variety of applications, but because of the variable hardness of the material it is difficult for Alexander's Stone Art to recommend it's use without knowing the properties of the specific onyx to be used. It is most often used for vertical surfaces and other areas where it's varying delicacy makes little difference.

Onyx Sample Images

All sample images listed in this site are for reference purposes only as natural materials can vary in coloration, veining, and pattern type. Please note that individual monitor settings may also affect the coloration & contrast of sample images.

Although most materials listed here are not truly onyx in a geological sense, the industry we work in recognizes these materials as being of similar aesthetic characteristic, if not mineral composition.
