Hedenbergite
The Forest-Dark Breaker of Walls
Also known as: Green Mongolian Quartz
About the stone

Hedenbergite is a dark-green to black calcium-iron silicate mineral in the pyroxene group, usually found in metamorphic rocks, especially iron-rich skarns formed where hot fluids alter surrounding rock. Anders Ludvig Hedenberg first found and described it at Mormorgruvan, Tunaberg, Sweden; Jöns Jakob Berzelius named it in his honor in 1819. Notable locations include Sweden, Russia’s Dalnegorsk district, Italy’s Elba Island, Pakistan, Australia’s Broken Hill, and Franklin, New Jersey. It has no widely used alternative English name, although historical German names include Funkit and Lodulit. Its crystal lore is modern rather than ancient, associating it with grounding, endurance, emotional steadiness, and navigating change.

Clean it with lukewarm water, a soft brush, and mild soap, then dry it. Avoid sudden temperature changes, ultrasonic cleaners, and harsh chemicals. Because it is a mineral with iron content, avoid soaking it for long periods.
