Physical properties

Formation & geological history

Picture jasper forms when silica-rich groundwater cements and replaces fine sediment, preserving layered or orbicular patterns; deposits are generally Phanerozoic, though the exact age depends on locality. Common sources include Oregon, Idaho, Utah, and Arizona, USA.

Uses & applications

Used for cabochons, carvings, beads, pendants, and decorative objects; valued mainly for attractive patterning rather than rarity.

Geological facts

The visible circular markings are natural mineral or sedimentary patterns, not necessarily fossils. “Picture jasper” is a trade name encompassing several patterned jasper varieties.

Field identification & locations

Identify it by its opaque body, fine grain, earthy colors, and lack of obvious cleavage; it should not scratch easily with a steel blade. Exact identification is difficult from an image because similar yellow jasper, brecciated jasper, or dyed stone can look alike.
