Physical properties
Hardness of 6.5 to 7 on the Mohs scale, vibrant red and white coloration, waxy to vitreous luster, and microcrystalline structure with conchoidal fracture.
Formation & geological history
Formed through the hydrothermal deposition of silica-rich fluids in rock fractures, creating quartz veins within iron-rich jasper.
Uses & applications
Commonly used in lapidary arts, tumbled stones, ornamental carvings, and low-cost jewelry.
Geological facts
Red jasper has been used since antiquity for talismans, seals, and decorative implements due to its durability and striking color.
Field identification & locations
Easily identified by its opaque red microcrystalline quartz body contrasted with white quartz veins; found globally in volcanic and sedimentary environments.
