Vedic astrology associates the black onyx gemstone with several benefits for those born under the star sign of Leo and anyone seeking protection and a boost to their inner power. Join us as we explore ancient beliefs about this bold power stone and the benefits of black onyx for people today.

Getting to Know the Black Onyx Gemstone

A kind of chalcedony, onyx is named after the Greek word meaning “claw” or “fingernail” — due to its mineral structure and banded coloring. Black onyx derives its color from the presence of iron and carbon and is typically (not always) present with bands of white.

Black Onyx and the Signs of the Zodiac

Vedic astrology from ancient India associates different types of gemstones with star constellations and planets. In this long tradition of astrological belief, the black onyx gemstone is linked with Leo birth dates, which are placed between July 23 and August 23 on the Tropical calendar and August 17 to September 16 on the Sidereal calendar. In Sanskrit, the Leo star sign is Simha. Black onyx is also the mystical birthstone for the month of December.

Black Onyx and the Planets

Vedic Hindu astrology links gemstones to a planet as well as a star sign, and the black onyx gemstone is used to represent the planet Saturn — helping the wearer to control him or herself in any situation while remaining grounded and composed. Black onyx is also said to increase one’s inner strength — boosting confidence and self-trust, instilling bravery and combating fear, and providing the discernment to make wise decisions.

In classical ceremonial magic, pieces of black onyx gemstone were carved into the shape of the head of the god Mars or the figure of Hercules and carried to give the wearer courage and bravery.

Black Onyx and the Root Chakra

The strength of black onyx is thought to offer benefits for the base of root chakra in Hindu belief — increasing one’s sense of the circle of the life and the realities of birth, death, and reincarnation. The root chakra is located at the base of the spine and is associated with strength, grounding, and our connection to the earth.

Protection for Travel

If you’re planning a trip or are simply wanting protection in general, a black onyx gemstone could be a good choice. Black onyx is thought to possess protective abilities for travel as well as warding off negativity and the evil eye.

Harmonious Relationships

Due to its closely intertwined layers of black and white, onyx has been used to represent the closeness and intimacy of relationships and thought to encourage romance, bonding, and sexual desire. The traditional gift for 7th and 10th wedding anniversaries, black onyx is thought to protect a relationship against conflicts and differences and protect against any external negativity that could damage the relationship.

Black Onyx and Your Health

Throughout history, gemstones and crystals have been used for healing and strengthening various systems in the body. In gemstone folk medicine, the black onyx gemstone has been used to sharpen one’s hearing, heal ailments related to the inner ear, and to strengthen the eyes, sensory system, motor nervous system, and immune system.

Designing the Ideal Black Onyx Gemstone Ring

If you are a Leo or would like to increase your inner strength, a black onyx gemstone ring is an excellent way to enjoy the benefits of black onyx while enjoying its unique aesthetic qualities and beauty. Teachers of Jyotish (Indian astrology) recommend a setting of silver, white gold, or yellow gold for your black onyx gemstone jewelry — though silver tones are preferred

They also recommended that you wear the ring on your left pinky finger or the middle finger — known as the “mount of Saturn” — to derive the maximum benefit from your black onyx gemstone
