Physical properties
Mohs hardness of 6.5 to 7; displays earthy to vitreous luster; microcrystalline quartz structure with opaque, multi-colored banded or patterned appearance.
Formation & geological history
Forms through the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often over millions of years.
Uses & applications
Used extensively in ornamental carvings, cabochons for jewelry, and as a popular specimen for mineral collectors.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and weaponry components due to its conchoidal fracture and durability.
Field identification & locations
Identify by its waxy luster, hardness that scratches glass, and opaque multicolored patterns. Found globally in riverbeds and mountainous regions.
