Formation & geological history
Formed from quartz-rich sandstone subjected to heat and pressure, often iron-stained.
Uses & applications
Decorative stone, landscaping, lapidary material.
Geological facts
The orange color is likely due to iron oxide staining (rust) within the rock.
Field identification & locations
Identified by its hardness (scratches glass), granular sugary texture, and lack of cleavage. Found in areas of past tectonic activity or as river-tumbled stones.
