Onyx is the mystical birthstone for December and astrological birthstone for Leo. Learn more about the ancient black onyx stone and its meaning to see whether a black onyx ring could be right for you.

Black Onyx in Geology

Composed of a form of quartz known as chalcedony, onyx is named after the Greek word for “claw” or “fingernail” thanks to the white and yellow veins observed in onyx marble. True onyx is a silicate mineral with parallel black and white bands that can also be found in the solid black color we use at AZEERA.

Sardonyx—the red and white variety of this mineral—is the traditional birthstone for the month of August and also holds an important place in gemstone astrology. However, as we specialize in black onyx, we will focus on this variety of the onyx birthstone.

The History, Symbolism, and Meaning of the Black Onyx Stone

The Legend of Cupid and Venus

According to Indian mythology, the goddess Venus (Rati) was found deep in slumber on the banks of the Indus River when Cupid (Kamadeva) decided to give her a manicure with his magic arrow. As the arrow clipped the fingernails of the sleeping goddess, the pared nails sunk to the bottom of the river and were transformed into the onyx birthstone.

Uses of Black Onyx

Historically, the onyx birthstone has been used in ornamental carvings and jewelry—with black-and-white onyx cameo gemstones being especially popular. In antiquity, onyx was carved into bases and handles for solid gold objects and engraved in negative relief for use in Roman seals.

Ancient Meanings of Black Onyx

Perhaps due to its intense coloring, onyx has traditionally been used as an amulet for protection when fighting in a battle or walking down a dark street at night. In supernatural ceremonies, onyx gemstones were carved with the image of the head of the planet Mars or the god Hercules to protect the person conducting the ritual. Ancient Indians and Persians believed that onyx provided protection against the evil eye and could help a woman to birth more quickly and easily when the stone was placed on her stomach.

Modern Meanings of Black Onyx

When given as a birthstone today, onyx is believed to boost the wearer’s sense of confidence, authority, and ability to be the master of his or her own destiny. It is also said to add more structure to the person’s life and provide wisdom for making good decisions.

With its parallel black and white bands, bicolor onyx has also enjoyed a long association with romance and thought to protect a relationship from outside influences that may disrupt its internal harmony. Onyx of any color is given for a 7th wedding anniversary and black onyx is given for a 10th wedding anniversary.

Medicinal Uses of Onyx

In crystal healing circles, the onyx birthstone is believed to increase the strength, stamina, and vigor of the wearer and boost their powers of self-control. It is also said to bring relief where there is tension, worry, and anxiety, and is thought to do away with confusion and nightmares.

Holistic approaches to medicine use onyx as a remedy for ailments involving the feet, blood, and bones—bone marrow in particular. If you suffer from epilepsy or glaucoma, onyx is believed to be helpful for these conditions, too.

Where Black Onyx is Found

In today’s gemstone industry, the onyx birthstone is produced in the largest quantities in Brazil, India, and Uruguay. However, deposits also exist in Peru, Afghanistan, Madagascar, and the U.S. In previous decades, Baja California and northwest Mexico produced significant amounts of onyx. Unfortunately, cheap imitations released in the gemstone market have had a negative impact on these North American centers of onyx production.
