This exotic natural stone is about luxury and glamor. Although onyx is a form of quartz, it is a softer and more fragile material. Great care is needed to maintain the natural beauty of this stone. Onyx marble is most often used as fireplace surrounds, bar tops, walls or small islands because it transmits light. It is best placed where it wont be used or abused on a day-to-day basis.
Onyx is often confused with marble, yet it is a significantly different type of rock. Onyx is a sedimentary rock, formed as stalactites and stalagmites in cave interiors. This formation method results in the cryptocrystalline construction of the rock fabric, and it is the size and uniformity of these crystals that contribute to the classic translucent property of most onyx varieties.
Although vulnerable to chemical and abrasive attack, the decorative appeal of onyx is perhaps unsurpassed by any other material.
