Physical properties
Hardness of 6.5 to 7 on the Mohs scale, opaque brick-red color due to iron inclusions, and a waxy to dull luster with conchoidal fracture.
Formation & geological history
Formed through the silification of sedimentary deposits or volcanic ash, typically in silica-rich marine environments over millions of years.
Uses & applications
Widely used in ornamental carvings, cabochons, jewelry making, and as a popular specimen for mineral collectors.
Geological facts
Ancient civilizations often used red jasper for amulets, seals, and weaponry due to its durability and striking earthy coloration.
Field identification & locations
Easily identified by its opaque red color, hardness that scratches glass, and smooth conchoidal breakage; found globally in regions with ancient volcanic or sedimentary activity.
