The name “onyx” is derived from the Greek word “ὄνυξ” (onyx), meaning “claw” or “fingernail,” due to the stone’s resemblance to a human nail in its banded varieties. White onyx, a less common but highly prized form, is named for its milky-white translucency, which exudes an aura of purity and serenity.
Composition and Formation
White onyx is a cryptocrystalline form of quartz, belonging to the chalcedony family. It is composed primarily of silicon dioxide (SiOâ‚‚) and forms through the deposition of silica in the cavities of volcanic rocks. Unlike pure quartz, which exhibits a crystalline structure, onyx develops in layers, giving it a smooth, banded or uniform appearance. The white variation is often formed when impurities are minimal, allowing for a strikingly clear or softly opaque stone.
Locations and Sources
White onyx can be found in various parts of the world, with significant deposits in Mexico, Pakistan, Afghanistan, Iran, Turkey, and Madagascar. The finest specimens often originate from Mexico and Iran, where onyx has been mined and utilised for centuries. The stone is commonly found in caves, limestone deposits, and geothermal springs, where mineral-rich water aids in its formation.
Physical Characteristics
White onyx is distinguished by its smooth, waxy lustre and translucent quality, often allowing light to pass through its surface. It has a Mohs hardness of around 6.5 to 7, making it relatively durable but still susceptible to scratches compared to harder gemstones. The stone’s natural beauty is often enhanced by polishing, revealing delicate banding or a soft, ethereal glow. Due to its layered structure, it can be carved and shaped into intricate decorative objects and jewellery pieces.
Archaeological Finds and Historical Usage
Throughout history, onyx has been revered by many ancient civilisations, including the Egyptians, Greeks, and Romans. White onyx, in particular, was favoured for its use in amulets, sculptures, and ceremonial artefacts. The Egyptians carved sacred objects and jewellery from the stone, believing it held protective properties. In Ancient Rome, onyx was often used in cameos and intaglios, where its layered structure allowed artisans to create detailed engravings. The Persians and Indians also valued white onyx for its supposed ability to ward off the “evil eye” and provide mental clarity.
Modern Applications
Today, white onyx continues to be highly sought after for both decorative and metaphysical purposes. It is commonly used in luxury interior design, where its striking translucency makes it ideal for backlit panels, countertops, and flooring. Jewelers craft white onyx into elegant pendants, rings, and beads, while spiritual practitioners utilise it for meditation, energy work, and holistic healing practices.
