About the stone

Red Agate, related to carnelian, is a chalcedony (cryptocrystalline quartz) in warm shades of red and orange.

Its color comes from iron oxides, often intensified by heating — a practice thousands of years old.

It forms layer by layer in the cavities of volcanic rock, each stone ending up one of a kind.

It has long been the stone of seals: the Romans and Greeks engraved their crests in carnelian because hot wax releases cleanly from it.

The most famous example is Napoleon’s carnelian seal, brought back from the Egyptian campaign, which he used for correspondence and bequeathed to his family.

Since antiquity it has been worn as a talisman of courage and protection, especially by soldiers and travelers.

Its color ranges from warm red to brick red, with a glossy and sometimes translucent appearance.

India (Gujarat) is a famous historic source; it is also found in Brazil and Uruguay.

Associated with vitality, courage, and stability, red agate is worn for energy and confidence.

With a hardness close to 7, it is durable and suitable for everyday wear—just avoid strong impacts and harsh chemicals.

Cleans easily with a soft cloth. This intense hue is beautifully highlighted in 925 silver and yellow gold.

Attention level

Cleaning

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.

Exposure precautions

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.

Storage

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).
