Manganese, the metal behind modern steel, comes mostly from ores like pyrolusite, and this small raw specimen shows its silver metallic ore still set into the host rock.
It is a low, flat piece, so it lies steady on a shelf or in a specimen drawer without needing a stand. The silver shines best in daylight, and a spot near a window shows off the contrast between the metallic ore and the duller matrix around it. Left raw and unpolished, it suits a mineral collector filling in the ore minerals, a geology fan, or anyone who prefers rough stones to tumbled ones. It is also an easy, small gift for someone just starting a rock collection.
Pyrolusite is mostly manganese dioxide and is the main ore of manganese. It ranges from black to light gray, sometimes bluish, with a metallic to earthy luster, and it usually grows as granular, fibrous or crusty masses; well shaped crystals seldom form. The name comes from the Greek for fire and to wash, after its old use removing color tints from glass.
Stone Meaning: Pyrolusite is traditionally associated with transformation and resilience.
