Physical properties
Hardness of 6.5-7 on the Mohs scale, opaque luster, various earth tones of color, and a conchoidal fracture.
Formation & geological history
Formed from silica-rich fluids precipitating in sedimentary environments or volcanic rocks over millions of years.
Uses & applications
Used extensively for ornamental carvings, polished cabochons, and in lapidary arts.
Geological facts
Jasper has been utilized since ancient times for talismans, seals, and decorative weaponry.
Field identification & locations
Identify by its waxy luster, lack of cleavage, and intricate opaque banding or patterns; commonly found worldwide in riverbeds and ancient hydrothermal deposits.
