Physical properties
Hardness 7 (Mohs scale), predominantly orange/tan with green veins, vitreous luster, granular texture, no distinct cleavage, specific gravity ~2.6-2.7
Formation & geological history
Formed through the metamorphism of quartz-rich sandstone, with later hydrothermal alteration introducing epidote in fractures.
Uses & applications
Decorative stone, landscaping, occasionally used in lapidary arts.
Geological facts
The orange color often comes from iron oxide staining, while the green is characteristic of epidote or chlorite.
Field identification & locations
Identified by its hardness (scratches glass), granular sugary texture under a loupe, and the distinct green epidote veining. Commonly found in metamorphic terrains.
