Physical properties

Hardness of 6.5-7 on the Mohs scale, waxy to dull luster, dense microcrystalline structure, and an opaque green color often with reddish or brown inclusions.

Formation & geological history

Formed through the hydrothermal deposition or silica-rich precipitation in marine environments, often associated with volcanic activity over millions of years.

Uses & applications

Used primarily for ornamental carvings, cabochons, lapidary art, and as a polishing stone for jewelry.

Geological facts

Jasper has been used since ancient times to create seals, talismans, and decorative items due to its durability and rich color.

Field identification & locations

Identified by its high hardness, conchoidal fracture, and lack of reactivity to acid; commonly found in riverbeds, hydrothermal veins, and sedimentary deposits worldwide.
