Picture Jasper

Physical Properties

Hardness: 6.5-7 (Mohs); Color: Tan, brown, ochre with darker banding; Luster: Vitreous to dull; Crystal structure: Trigonal (microcrystalline); Cleavage: None; Specific gravity: 2.58-2.91

Formation & Geological History

Formed through the accumulation of fine-grained silicate and iron oxides in sedimentary environments. The distinct banding is caused by the rhythmic precipitation of minerals in ground water or volcanic ash layers over millions of years.

Uses & Applications

Popular for lapidary work, jewelry making (cabochons), interior decoration, and as a collector's stone due to its scenic, landscape-like patterns.

Geological Facts

This variety is often referred to as 'landscape jasper' because the intricate banding can resemble hills, trees, or desert scenes. It is essentially a fossilized mud found in ancient volcanic flows.

Field Identification & Locations

Identify by its opaque nature, high hardness, and earthy, landscape-like banding. It is commonly found in desert regions of the Western United States, particularly Oregon and Idaho.
