Physical properties
Hardness of 6.5 to 7 on the Mohs scale, red to reddish-brown color, vitreous to dull luster, microcrystalline quartz structure, conchoidal fracture.
Formation & geological history
Formed through the hydrothermal accumulation of silica-rich fluids or chemical precipitation in marine environments, often dating from Precambrian to Mesozoic eras.
Uses & applications
Widely used in cabochons, beads, ornamental carvings, and metaphysical crystal healing practices.
Geological facts
Red jasper has been utilized since ancient times for amulets, seals, and weaponry components by various civilizations like the ancient Egyptians.
