Physical properties

Formation & geological history

Formed through the precipitation of silica-rich fluids in sedimentary environments or hydrothermal veins, often associated with volcanic activity and ancient ocean floors over millions of years.

Uses & applications

Used in ornamental carvings, cabochons for jewelry, decorative objects, and favored by collectors.

Geological facts

Jasper has been used since ancient times for talismans, seals, and weaponry. Green varieties are often associated with growth, renewal, and grounding energies in metaphysical traditions.

Field identification & locations

Can be identified in the field by its waxy-to-dull luster, conchoidal fracture, hardness that scratches glass, and opaque green color. Commonly found in riverbeds, glacial tills, and areas with ancient volcanic or hydrothermal activity worldwide.
