Onyx is a singular stone, imbued with charisma, elegance, and mystery. While its surface may feature a few white or brown bands, it remains so dark it could easily be mistaken for pure black. A symbol of strength, this intense semi-precious stone has been prized across centuries and civilizations for its many virtues - which is how the onyx ring became a timeless classic!
Its name comes from the Greek "onux," meaning "nail" or "claw." This unusual name has its roots in Greek mythology, in which Cupid once trimmed the nails of the goddess Aphrodite while she slept. Using the tip of an arrow, he let the clippings fall onto the sandy riverbank, where the Fates transformed them into onyx stones. Artifacts made from this dark gem dating back to antiquity have been found in Egypt, Crete, and Italy. Onyx was used as an ornamental stone, a decorative object, and in the crafting of cameos and intaglios. It was also mentioned by Pliny the Elder in his Natural History encyclopedia, which distinguished two varieties of onyx and discussed the possibility of altering its color.
The symbolism of this semi-precious stone has varied widely across eras and cultures. While India saw it as a protective talisman against evil forces, medieval Europe attributed malevolent and discord-bringing properties to onyx. In China, it was also considered a bad omen, with rocks extracted solely for export. For Arab civilizations, the stone's dark color evoked sadness above all else - an association that carried into the use of onyx in jewelry during the Victorian era. Much like hematite, this enigmatic stone was crafted into jewelry worn by those in mourning. Today, however, onyx marks the 7th wedding anniversary.
Onyx forms at low temperatures in volcanic rocks, metamorphic rocks, and hydrothermal veins. These varied geological environments have led to the discovery of significant deposits around the world, notably in Germany, Austria, Madagascar, Brazil, Uruguay, Argentina, Australia, the United States, India, and Mexico.
Long prized for making seals in antiquity and the Middle Ages - thanks to a surface that wax wouldn't stick to - onyx is today used primarily in jewelry for crafting pieces of varying intricacy, as well as in décor and ornamental work.

Onyx is a variety of agate - and therefore of chalcedony - placing it within the quartz family. Its trigonal crystal structure is composed of silicon dioxide (SiO2). A relatively sensitive gem, this deep black stone has a hardness of 6 to 7 on the Mohs scale and a density of 2.5 to 2.6.
With a vitreous to resinous luster, onyx can display a black, opaque, or slightly translucent color depending on the specimen. This semi-precious stone is also often marked by transparent, white, or dark circular or polygonal bands. When a specimen is black and white, it is referred to as "banded onyx." Conversely, if the gem displays a translucent brown or red color with white, it is known as "sard" or "sardonyx." Some specimens can be entirely black, offering a deep and enigmatic appearance that is highly prized in jewelry. It is worth noting that these are sometimes the result of deliberately dyed chalcedony. While the process is perfectly permitted, the jeweler must clearly disclose this.
The metals most commonly paired with onyx tend toward cool tones, such as silver or white gold. Their bright luster helps bring out the intense hue of the onyx to full effect. That said, these semi-precious stones are sometimes set in yellow or rose gold settings, though such creations are considerably rarer.
Onyx is a semi-precious stone that offers many natural benefits to its wearer. On an emotional level especially, this black gem provides strength during difficult times, making it a powerful ally for those dealing with stress, sadness, or emotional upheaval. It also has a positive effect on depressive states by helping to reduce negative emotions. A stone of grounding and rootedness, onyx is used in meditation to refocus energy, foster greater self-control, and enhance mental stability through improved concentration. With greater self-confidence and a sense of hope for the future, onyx also helps cultivate a stronger sense of responsibility.
The varied properties of this semi-precious stone also provide a range of physical benefits for the wearer. It is said to have a highly beneficial effect on blood circulation, helping to strengthen the heart, kidneys, spleen, pancreas, and nerves. Onyx is also recognized for its positive effects on the entire auditory system, including its ability to help treat tinnitus, buzzing, and ear infections. This gem can also prove equally effective in addressing skin and hair concerns, and for general eye health.
To care for your onyx gem or jewelry, store it in a separate pouch or box. This keeps the stone protected from knocks and scratches that could occur through contact with other pieces in your collection. It is also strongly advised to keep onyx away from acidic products such as detergents, nail polish remover, and vinegar.
To preserve the deep luster of your gem, periodic cleaning may be needed. Simply soak the stone in a bowl of warm, soapy water, then gently scrub the surface with a small soft-bristled brush. After rinsing with clean water, dry the onyx thoroughly with a soft cloth to prevent any limescale deposits that could damage the unique aesthetic qualities of your stone.
The way the lapidary has worked the different black and white sections of the onyx to enhance the stone's aesthetics is one of the first criteria to consider. The quality of the polishing work directly contributes to the quality of the finished gem set in a jewelry piece. The shading and opacity of onyx, on the other hand, come down to personal taste and allow for many variations so you can find a piece that's perfectly suited to you.

Onyx is a semi-precious stone that is black and more or less opaque, featuring parallel bands of different colors running through its internal structure. These characteristics also make it a gem that holds up exceptionally well to intense heat - genuine onyx does not deform when exposed to high temperatures. A specific treatment may, however, have been used to intensify its naturally dark color. This process is always clearly disclosed by the seller. If you prefer a fully natural purchase, it's important to pay close attention to this information.
Somewhat delicate, onyx requires a few precautions to preserve its natural brilliance. Store it in a dedicated pouch or box to protect it from the knocks and scratches that contact with other jewelry or gemstones can cause. Avoid all contact with acidic products. When cleaning, use warm water and a gentle brush, then wipe it dry thoroughly with a soft cloth after rinsing.
