Picture Jasper

Physical Properties

Hardness: 6.5–7 on Mohs scale; Color: Tan, brown, and cream with dark dendrites; Luster: Vitreous to waxy; Crystal structure: Hexagonal/Trigonal (Microcrystalline); Cleavage: None.

Formation & Geological History

Formed through the petrification of mud or volcanic ash in high-pressure hydrothermal environments. The landscape-like patterns are created by flow patterns of water and minerals (like iron) as they seep through the stone during formation.

Uses & Applications

Primarily used for lapidary work, jewelry (cabochons), interior decoration, and as a collectible metaphysical stone.

Geological Facts

Named Picture Jasper because the dendritic inclusions and banding often resemble landscapes or scenic paintings. Most high-quality specimens come from the Owyhee Mountains and Biggs Junction areas.

Field Identification & Locations

Identify by its tan-to-brown earth tones and scenery-like markings. Common in desert regions of Idaho and Oregon. Collectors look for high contrast and clear images.
