Physical properties

Hardness: 6.5-7 (Mohs scale); Color: Brick red to brownish-red; Luster: Dull to vitreous; Crystal Structure: Trigonal (microcrystalline); Cleavage: None; Specific Gravity: 2.58-2.91

Formation & geological history

Formed when microcrystalline quartz precipitates from silica-rich fluids in fissures or cavities. The red color is derived from high concentrations of iron oxide (hematite) during the sedimentation process.

Uses & applications

Used extensively for lapidary work, jewelry (cabochons and beads), ornamental items, and as a popular stone for chakra healing and crystal collecting.

Geological facts

Red Jasper has been used since ancient times for talismans and seal stones; it was often referred to as 'the stone of endurance' or 'warrior stone' in various cultures.

Field identification & locations

Identified in the field by its opaque red color, wax-like luster when wet, and inability to be scratched by a steel knife. Frequently found in riverbeds, desert washes, and gravel pits globally.
