Overview
Limonite is an earthy, yellow-brown to dark brown mineral mixture, not a true mineral but a hydrated iron oxide with variable composition. It commonly forms as a secondary mineral from the weathering of iron-rich minerals and is a significant iron ore. Limonite has been valued since antiquity for pigment production and its role in the iron industry. In metaphysical and holistic practices, limonite is associated with grounding, clarity, and personal transformation.
