Geological Formation and Sources
Onyx is a form of chalcedony, a microcrystalline variety of quartz. It is characterized by its parallel bands of color, which can range from black and white to red, brown, and green. These bands are formed through the slow deposition of silica-rich solutions in the cavities of volcanic rocks. This process creates a layered structure, which gives onyx its distinctive appearance.
The most commonly recognized form of onyx is the black variety, which is often polished to a deep, lustrous finish. When referring to the onyx gemstone, one usually speaks of an all-black stone or a white-banded stone against a black background. This beautiful, textured appearance has made it a favorite for jewelry and ornamental objects for millennia.
Geographically, onyx is sourced from various locations around the world. The most significant sources include Brazil, Uruguay, India, and the state of California in the United States. These regions provide the necessary geological conditions for the formation of high-quality onyx, ensuring a steady supply for the gemstone market.
Gemological Properties
Onyx possesses a unique set of physical and chemical characteristics that define its identity as a gemstone. As a variety of microcrystalline quartz, its chemical composition is silicon dioxide (SiO₂). It has a hardness of 7 on the Mohs scale, making it a relatively durable stone suitable for a wide range of jewelry applications, including rings, pendants, and bracelets.
Its crystal system is trigonal, and it exhibits a vitreous luster when polished, contributing to its appealing shine. Onyx typically has a specific gravity ranging from 2.65 to 2.67 and a refractive index of approximately 1.535 to 1.539. While it is often associated with a solid black color, the stone can exhibit bands of white or other colors, which are a result of its formation process.
