Physical properties
Hardness of 6.5-7 on Mohs scale; displays varied earthy tones with banded or mottled patterns; waxy to vitreous luster.
Formation & geological history
Formed through the precipitation of silica-rich fluids in sedimentary environments or volcanic ash beds over millions of years.
Uses & applications
Widely used for ornamental carvings, polished cabochons in jewelry, and geological specimen collecting.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components across various civilizations.
