Physical properties

Hardness: 7 (Mohs); Color: Pale green with reddish-brown spots; Luster: Vitreous to waxy; Texture: Granular and microcrystalline; Grainy appearance when fractured.

Formation & geological history

Formed from the metamorphism of quartz sandstone under high heat and pressure, typically during mountain-building events. The green tint is often caused by fuchsite (chrome-mica) or chlorite, while the red spots are hematite (iron oxide).

Uses & applications

Used in construction for road ballast and flooring, as a decorative stone in landscaping, and sometimes as a minor gemstone for cabochons.

Geological facts

Quartzite is so tough that it often outlasts the surrounding rocks in a landscape, forming the caps of hills and ridges. It is often confused with marble but is much harder and will scratch glass.

Field identification & locations

Identify by its extreme hardness (cannot be scratched by steel) and lack of reaction to acid. Look for it in glaciated areas or riverbeds near ancient mountain ranges.
