Physical properties
Mohs hardness of 6.5 to 7. Displays opaque earth-tones, red, brown, or yellow colors with a waxy luster and conchoidal fracture.
Formation & geological history
Formed through the silification of sedimentary or volcanic rocks rich in silica, occurring over millions of years.
Uses & applications
Used primarily for ornamental carvings, cabochons, and gemstone jewelry.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components like arrowheads.
Field identification & locations
Identified by its high hardness, inability to be scratched by steel, and completely opaque, fine-grained texture.
