Physical properties
Hardness of 6.5 to 7 on the Mohs scale, red to reddish-brown color, waxy luster, and conchoidal fracture with no cleavage.
Formation & geological history
Forms from the accumulation of silica-rich sediments and iron oxides, often in marine environments, through low-temperature precipitation.
Uses & applications
Used extensively for ornamental carvings, cabochons, polished decorative stones, and lapidary collections.
Geological facts
Red jasper has been used since ancient times for seals, talismans, and jewelry due to its durability and rich color.
Field identification & locations
Easily identified by its opaque red color and smooth, waxy fracture; commonly found in riverbeds and ancient sedimentary deposits worldwide.
