Onyx is a type of Chalcedony that occurs naturally with tiny banded parallel layers. The mineral was first reported in 77 A.D. by Gaius Plinius Secundus (Pliny the Elder) and named after the Greek word “claw” or “fingernail” because of its similar resemblance. The name got its use because of the shape and brightness of the bands Onyx shows when sliced. A variety of colours are commonly found throughout various countries of the world. These countries include Mexico, Argentina, Brazil, Australia, South Africa, Madagascar, India, and the United States.
Onyx is a cryptocrystalline form of quartz. The colours of its bands range from white to almost every colour except shades such as purple and blue. Commonly specimens of onyx available contain bands of colours of white tan and brown. Pure black onyx is the most famous variety and has a long history of use for hardstone carving and jewellery.
Onyx has been used for thousands of years and has a long history with many different civilizations. The Ancient Egyptians used Onyx in 3,000 B.C. to make pottery items and other utensils. The Ancient Roman and Greek societies used Onyx for jewellery, amulets, and carving materials.
