Onyx: significance, properties and virtues
In summary

Onyx is a natural stone with a deep black color, often adorned with white or colored bands, that is prized in both jewelry and jewelry. Mainly mined in Brazil, Mexico and India, it is recognized for its charm and symbolism of protection, while offering numerous possibilities for the creation of DIY jewelry.

Long associated with mourning and evil spells, black onyx has established itself as a timeless classic in jewelry. It appeals to both men and women. It is also used in crystal healing, where it is considered a protective stone.

Did you know that black onyx isn’t actually black to begin with? It’s a light or grayish chalcedony that’s naturally porous. To achieve this intense black color, it is immersed in a sugar solution and then heated in the presence of acid, which carbonizes the sugar absorbed by the stone. This ancient and common process makes the color deeper and more durable. The stone is thus dyed, but it remains a natural stone.
Good to know:Natural, untreatedblack onyx is much rarer and more expensive. It is not commonly found in costume jewelry.

What is the meaning of onyx?

The name of this natural stone, which belongs to the family of fine stones (formerly known as semiprecious stones), comes from the Greek word “onyx,” meaning “nail” or “claw.”

The origin of onyx

This gemstone has been known since ancient times.
The Indians and Persians believed that onyx was a good-luck charm that protected them from the evil eye. In contrast, the Chinese considered it a bringer of bad luck.

In the Middle Ages, onyx had a bad reputation. Its black color was associated with anger, hatred, and evil spells.

During the Victorian era, it was customary to wear onyx to observe mourning, such as that for Queen Victoria, since other colors were forbidden.

Throughout history, the color of onyx has inspired many civilizations to create a wide variety of objects:

  • plates, jars, and bowls in Egypt, as well as vases—the most famous of which are the Cup of Ptolemy and the Onyx Jug.
  • jewelry such as camés (the most famous being the Sainte-Chapelle Caméo and the Gonzaga Caméo), seals, and signet rings engraved with various symbols among the Romans. Archaeologists have discovered earrings made of onyx beads in ancient Egyptian tombs. Many kings of France appreciated it: Louis XV had a seal made of onyx, gold, and carnelian, decorated with the motto “Love Unites Them” and a portrait of Madame de Pompadour. Gabrielle d’Estrée, Henri IV’s mistress, wore an onyx pendant bearing the king’s likeness.

What color is onyx?

One might think that black onyx is simply an opaque black stone, but that is not the case at all. What makes this gemstone unique are the white or contrasting-colored bands (green, red, brown, or white) that run through it.
Because of its similar color, onyx is sometimes confused with black obsidian.

Onyx can also be found in other colors, such as brown, green, red, or white.

Where is onyx found?

The main deposits of onyx are located in Brazil, Mexico, the United States, India, Uruguay, and Madagascar.

What are the properties of black onyx?

In crystal healing, onyx is considered a positive stone. It is said to help boost self-esteem, confidence, and self-control. It is said to promote stability and strength. Considered an energetic shield, it is believed to absorb and repel negative energies and help protect against harmful influences.
It is said to be perfect for successful meditation.

Black onyx is associated with the root chakra. It is said to promote a sense of security, calm, and stability.

How do you recharge black onyx?

Like all natural stones, onyx will lose its energy over time. That’s why it’s important to cleanse and recharge it regularly.
To purify it, soak your gemstone in a container of salt water for a few hours, avoiding tap water. Be sure to dry it with a soft cloth afterward.
To recharge it, it’s recommended to place your stone in direct sunlight for a few moments. To make this process more effective, you can place it on a cluster of quartz.

How should you wear black onyx?

The black color of onyx has the advantage of pairing equally well with gold tones and silver tones. For those who prefer gold, choose gold-plated or Gold Filled jewelry findings to make your own DIY costume jewelry. For those who prefer silver, opt for 925 Sterling Silver or stainless steel jewelry components.

Which stone pairs well with onyx? In crystal healing, onyx is considered a fairly neutral stone that pairs very well with carnelian, amethyst, and moonstone. To boost the root chakra, it’s recommended to wear it with jasper, bronzite, hematite, lava stone, pyrite, or garnet. When paired with obsidian or black tourmaline, its protective power is enhanced.
However, it is advisable to avoid pairing onyx with stones that are too powerful or too energizing, such as turquoise, malachite, peridot, or tiger’s eye.
