Onyx is a type of chalcedony, a cryptocrystalline form of quartz, with a fine, even grain and a glossy finish. It is typically black or dark in color, but can also occur in shades of brown, red, and green. Onyx is often used for jewelry and decorative objects due to its striking appearance.
Onyx is composed primarily of silicon dioxide (SiO2), the same mineral that makes up quartz. It can also contain small amounts of other minerals such as iron, calcium, and manganese.
Onyx is formed through the slow crystallization of silica-rich solutions in underground cavities or other geologic features. As the solutions cool, they deposit layers of silica that gradually build up into the distinctive banded patterns seen in onyx.
Onyx is found in many parts of the world, including Mexico, Brazil, Pakistan, India, and the United States.
Onyx is believed to have several benefits for the wearer, including:
- Providing protection against negative energy and enhancing feelings of safety and security
- Boosting mental and physical strength, stamina, and perseverance
- Helping to release old emotional wounds and promote inner healing
- Enhancing focus, concentration, and self-discipline
- Promoting feelings of calm and relaxation.
