Physical Properties

Hardness: 6.5-7 on Mohs scale; Color: Reddish-brown to orange-red; Luster: Vitreous to dull; Crystal structure: Trigonal/Hexagonal; Cleavage: None; Features 'aventurescence' (sparkling effect from inclusions).

Formation & Geological History

Formed as a metamorphic rock (Quartzite) from quartz-rich sandstone subjected to high heat and pressure, with high concentrations of hematite or goethite giving it the red color.

Uses & Applications

Commonly used for ornamental carvings, polished points, beads, and metaphysical specimens.

Geological Facts

The characteristic shimmer is called aventurescence, caused by light reflecting off tiny platelets of mica or iron minerals within the quartz.

Field Identification & Locations

Look for the subtle sparkle under bright light and the grainy quartzite texture. It is distinguished from Red Jasper by its relative translucency and internal flakes.
