Physical properties
Hardness of 6.5-7 on Mohs scale, opaque green coloration, waxy luster, trigonal crystal system, and conchoidal fracture.
Formation & geological history
Formed through the hydrothermal deposition of silica-rich fluids or precipitation in marine sedimentary environments.
Uses & applications
Used primarily in lapidary work, ornamental carvings, jewelry making, and as a collectible mineral specimen.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry components across various civilizations.
Field identification & locations
Identified by its distinctive green color, lack of cleavage, and high hardness that scratches glass; commonly found in riverbeds and mountainous regions worldwide.
