Physical properties
Hardness 6.5-7 on Mohs scale; color deep reddish-brown to brick red with dark inclusions; vitreous to dull luster; trigonal crystal system (microcrystalline); poor/no cleavage; specific gravity ~2.6.
Formation & geological history
Formed through the deposition of silica rich solutions containing microcrystalline quartz and iron oxide particles in hydrothermal or sedimentary environments.
Uses & applications
Popular in jewelry making for pendants, beads, and cabochons, as well as decorative carvings, tumbled stones, and holistic healing collections.
Geological facts
Red jasper has been used as a gemstone since antiquity. In ancient Egypt, it was associated with Isis and carved into amulets to symbolize protection.
Field identification & locations
Identified by its opaque, rich red color, high hardness that scratches glass, and smooth conchoidal fracture. Widely found in Brazil, India, Madagascar, Russia, and the USA.
