Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy to vitreous luster, opaque transparency, conchoidal fracture, and varied reddish-brown to beige colors.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or volcanic ash beds over millions of years.
Uses & applications
Used primarily for jewelry making, beading, and ornamental carvings.
Geological facts
Jasper has been used since ancient times for talismans, seals, and weaponry due to its durability and attractive patterns.
Field identification & locations
Identified by its opaque nature, hardness, and lack of cleavage. Often found in riverbeds and mountainous regions worldwide.
