Physical properties
Hardness of 6.5 to 7 on the Mohs scale, dull to waxy luster, opaque, green color often with subtle mottling, conchoidal fracture, specific gravity around 2.58 to 2.91.
Formation & geological history
Formed through the deposition of silica-rich sediments or volcanic ash in marine environments, followed by diagenesis and lithification over millions of years.
Uses & applications
Used for making cabochons, beads, ornamental carvings, and as a collector's mineral specimen.
Geological facts
Jasper has been used since ancient times for talismans, seals, and jewelry. Green varieties are particularly associated with grounding and tranquility in metaphysical traditions.
Field identification & locations
Can be identified in the field by its distinct green color, hardness that scratches glass, and smooth conchoidal fracture. Commonly found in riverbeds and areas with ancient hydrothermal or sedimentary activity.
