Arfvedsonite
The Dark Mirror of Inner Light
About the stone
Arfvedsonite is a sodium- and iron-rich amphibole mineral, typically dark green to blue-black, that forms elongated crystals in alkaline igneous rocks. First discovered in 1823 at Kangerluarsuk Fjord in southern Greenland, it was named in honor of Swedish chemist Johan August Arfwedson, the discoverer of lithium. Notable sources include Greenland’s Ilímaussaq complex, Mont Saint-Hilaire in Quebec, Russia’s Kola Peninsula, and Norway. In modern crystal lore, arfvedsonite symbolizes mental clarity, fresh beginnings, and turning intentions into action.

Care and handling
Arfvedsonite is an amphibole mineral and is brittle, so handle gently. Like other amphiboles, it can break into fine shards or fibres, so avoid grinding or scraping it, avoid breathing any dust, wash your hands after handling, and do not use it in water, elixirs or the mouth. Keep it from children and pets. Wipe clean with a dry or barely damp cloth.
Individual experiences with Arfvedsonite vary, and its effects are personal rather than guaranteed. Use it mindfully, handle it safely, and seek qualified support for any body image or health concern.
