Onyx was highly valued by the Romans, who used it to create intricate carvings and jewelry. Throughout history, onyx has been associated with various cultures and mythologies, often symbolizing protection, strength, and grounding energy.

Onyx Colors

Onyx can be found in a range of colors, including black, white, red, brown, and green. The most common and sought-after variety is black onyx, which often features contrasting white bands. The colors of onyx are typically formed by impurities within the chalcedony, such as iron, manganese, and other trace elements.

Onyx Hardness

Onyx has a hardness of 6.5 – 7 on the Mohs scale, making it a relatively hard and durable stone. It is resistant to scratches and can be polished to a high luster, making it an ideal choice for jewelry and decorative carvings.

Sardonyx

Sardonyx is a variety of onyx that features reddish-brown and white bands. The name “sardonyx” comes from the combination of “sard,” a reddish-brown variety of chalcedony, and “onyx.” Sardonyx has been used for centuries to create intricate cameos and intaglios.
