About the stone

Green Onyx is a chalcedony (cryptocrystalline quartz) wrapped in a lively, vivid green.

It's only fair to say: this color isn't natural — the pale base stone is dyed.

It's a traditional technique, perfected in major cutting centers like Idar-Oberstein; the intense, even green is the hallmark of this craft.

Chalcedony, the family it belongs to, has been used for thousands of years for cameos, seals, and amulets.

Green onyx is a modern variant, prized for its smooth, homogeneous look, which makes it popular in contemporary jewelry.

The color is a vibrant, glossy, consistent green that creates a fresh, elegant look.

Associated in various cultures with balance, prosperity, and positive energy, green onyx is said to bring calm and stability.

With a hardness close to 7, it's fairly durable, but may show fine fissures under strong impacts.

Harsh chemicals can affect its color, so it's best kept away from them and from impacts.

It cleans easily with a soft cloth. Its vivid green is beautifully showcased in 925 silver.

Attention level

Warm water with soap or a gentle professional jewelry solution.
Avoid ultrasonic cleaners if the stone is not clearly compatible (e.g., some amethysts or topazes may be affected).
Avoid steam cleaning unless specifically safe for that stone.

Remove jewelry before intense physical activities or entering chlorinated pools.
Avoid contact with strong chemicals (chlorine, ammonia).
Some stones may lose color with prolonged sun exposure; store them properly.

Store in soft pouches or separate compartments to prevent scratches.
If the metal oxidizes easily (like some silver alloys), consider anti-tarnish strips.
Avoid areas with high humidity (bathrooms, saunas).
