Physical properties

Hardness: 6.5-7 (Mohs scale), Color: Yellow, orange with dark dendritic streaks, Luster: Vitreous to waxy, Crystal Structure: Trigonal (microcrystalline), Cleavage: None/Conchoidal fracture

Formation & geological history

Formed primarily from the deposition of silica from water or hydrothermal solutions, often in volcanic environments or sedimentary beds. The coloration comes from iron oxides and various mineral inclusions.

Uses & applications

Used extensively in jewelry as cabochons, for decorative ornamental carvings, and as a popular specimen for rock tumbling and metaphysical collections.

Geological facts

Jasper was a favorite gem in the ancient world; its name can be traced back in Arabic, Persian, Hebrew, Assyrian, Greek, and Latin. It is an opaque variety of chalcedony.

Field identification & locations

Identify by its hardness (cannot be scratched by a steel knife), opaque nature, and smooth, almost plastic-like waxy feel when polished. Commonly found in riverbeds and desert environments globally.
