Physical properties
Hardness of 7 on the Mohs scale, opaque with earthy to vitreous luster, featuring red and grey tones with a crystalline cavity.
Formation & geological history
Formed through silica-rich fluids precipitating in sedimentary or volcanic rock cavities over millions of years.
Uses & applications
Used primarily in lapidary arts, ornamental carving, and mineral specimen collecting.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and decorative ornamentation.
Field identification & locations
Identify by its conchoidal fracture, lack of visible crystal grains, and high hardness that scratches glass.
