Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque red color, dull to waxy luster, and microcrystalline trigonal structure.
Formation & geological history
Formed through the silification of sedimentary deposits or volcanic ash, typically enriched with iron oxides imparting the red hue.
Uses & applications
Used primarily for ornamental carvings, cabochons, and gemstone jewelry or as a decorative collector stone.
Geological facts
Red jasper has been utilized since ancient times for amulets and seals due to its durability and rich color.
Field identification & locations
Identified by its opaque appearance, Conchoidal fracture, and lack of reactivity to acid; commonly found worldwide in riverbeds and ancient seabed formations.
