Agate, gemstone, origin, characteristics, symbolism and jewelry

Stone profile

• Family or nature: Microcrystalline variety of quartz, often recognizable by its bands
• Colors: White, gray, brown, red, blue, green or multicolored depending on inclusions and treatments
• Symbolic associations: stability, grounding and continuity

Characteristics and origin

Agate belongs to the chalcedony family. It generally forms through successive deposits of silica in rock cavities, which explains its bands and patterns. Deposits are found notably in Brazil, Uruguay, India, Madagascar and several volcanic regions.

Traditional symbolism

In lithotherapy traditions and certain cultural practices, this material is associated with the following themes: stability, grounding and continuity. These associations are cultural, spiritual or personal references. They do not describe an effect produced by the stone.

Agate in jewelry

Its hardness of about 6.5 to 7 on the Mohs scale and the diversity of its patterns make it a popular material for beads, cabochons and pendants. Some very bright colors can result from dyeing; the jewelry description should then indicate the finish offered.

Care: A soft cloth, lukewarm water and mild soap are generally sufficient. Avoid impacts, harsh products and sudden temperature changes.
