Ferruginous Quartz
The Rust-Red Anchor of Resolve
Also known as: Eisenkiesel, Hematoid Quartz, Fire Quartz
About the stone
Ferruginous quartz is quartz colored yellow, orange, red, or brown by iron-bearing inclusions or coatings, commonly hematite and goethite. Its name comes from the Latin ferrugo, meaning “iron rust”; because it is a widespread quartz variety rather than a separately discovered mineral species, no single discoverer or first-discovery date is reliably established. Notable sources include Spain, Germany, England, Namibia, Brazil, and Russia. Additional names include Eisenkiesel (“iron pebble”), hematoid quartz, red quartz, and fire quartz; orange, surface-stained specimens are often marketed as tangerine quartz, although these names are not exact synonyms for every specimen. Modern crystal lore associates it with grounding, emotional balance, clarity, and confidence.

Care and handling
Ferruginous Quartz is hard and durable, and its color is part of the stone, not a surface layer. Be wary of market imitations such as dyed or dusted “tangerine quartz,” whose color can rub off. Clean with lukewarm water, mild soap, and a soft cloth, then dry; avoid harsh chemicals, soaking, and sudden temperature changes. The iron oxide may leave a faint stain on porous surfaces, so set it on a protective cloth.
Individual experiences with Ferruginous Quartz vary, and its meanings are matters of reflection rather than proof. Use it as an earthy companion for forgiveness and perseverance.
