\nOnyx is predominantly composed of silicon dioxide (SiO\u2082) and is characterized by its distinctive striated appearance, which can range from black and white to shades of brown, green, and red. The most prized variety, black onyx, has a deep, solid hue often contrasted by white or cream-colored striations. The stone is formed through the deposition of silica from groundwater in volcanic rocks, resulting in the layered appearance that distinguishes it from other chalcedons such as agate.
