Physical properties

Hardness: 6.5-7 on Mohs scale. Color: Tan, brown, yellow, often with landscape-like patterns. Luster: Vitreous to dull. Crystal structure: Cryptocrystalline quartz (chalcedony). Cleavage: None.

Formation & geological history

Formed from silica-rich groundwater percolating through sedimentary rocks or volcanic ash, depositing silica along with impurities like iron oxides which create the distinctive patterns.

Uses & applications

Used primarily in lapidary arts for cabochons, beads, and ornamental carvings.

Geological facts

Picture jasper is highly valued for its intricate patterns that often resemble miniature landscapes, hills, or abstract scenes.

Field identification & locations

Identifiable by its opaque nature, characteristic tan/brown colors, and distinct landscape or banding patterns. Often found in the Western US, particularly Oregon and Idaho.
