Physical properties
Hardness of 7 on Mohs scale. Colors include green, gray, and brown with a distinct red jasper or hematite vein. Vitreous to dull luster with conchoidal fracture.
Formation & geological history
Formed through the regional metamorphism of quartz-rich sandstone, subsequently fractured and healed by hydrothermal solutions carrying iron-rich minerals.
Uses & applications
Used primarily as a decorative stone, lapidary material for cabochons, and as a geological specimen for collectors.
Geological facts
The striking red line is an intrusion or healed fracture filled with microcrystalline quartz and iron oxide, often referred to as a sedimentary or hydrothermal dike.
Field identification & locations
Identify by its extreme hardness, resistance to scratching by steel, and the prominent contrasting mineral vein running across the weathered surface.
