Aurichalcite is a delicate blue to green copper-zinc carbonate mineral, typically forming silky tufts of tiny needles in the oxidized zones of ore deposits. First described in 1839 by Theodor Böttger from material at the Loktevskoye mine in Russia’s Altai region, it was named after orichalcum, an ancient term for a brasslike metal, reflecting its copper and zinc content. Notable sources include Mexico’s Ojuela mine, Laurion in Greece, Tsumeb in Namibia, and Bisbee, Arizona. Its most distinctive link to lore is through its name: Plato described orichalcum as a prized metal of legendary Atlantis

Care and handling

Aurichalcite contains copper and zinc, which can be toxic if ingested. Wash your hands after handling it, never use it in water, elixirs or gem infusions, never put it in the mouth, and keep it from children and pets. It is very soft and fragile: do not grind, scrape or scrub it, and avoid creating dust. Wipe gently with a dry soft brush, and keep it away from acids and moisture.

Individual experiences with Aurichalcite vary, and its effects are personal rather than promised. Admire it as a delicate treasure, handle it safely, and let it inspire reflection without replacing professional care.
