Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque red to reddish-brown color with a vitreous to dull luster, and a microcrystalline quartz structure with conchoidal fracture.
Formation & geological history
Forms through the hydrothermal deposition of silica-rich fluids or alteration of sedimentary deposits, often enriched by iron oxides in marine environments.
Uses & applications
Widely used in jewelry making, ornamental carvings, polished decorative stones, and lapidary collections.
Geological facts
Ancient civilizations prized red jasper as a sacred talisman of courage and used it to create seals and amulets.
Field identification & locations
Easily identified by its opaque red color and microcrystalline texture; commonly found worldwide in riverbeds and ancient seabed formations.
