Physical properties

Hardness: 6.5-7; Color: Brown, tan, black, with landscape-like patterns; Luster: Vitreous to dull; Crystal structure: Microcrystalline; Cleavage: None; Specific gravity: 2.58-2.91

Formation & geological history

Formed from silica-rich fluids that percolated through volcanic ash or other fine-grained sedimentary rocks, precipitating microcrystalline quartz and trapping iron oxides or other minerals that create the distinct patterns.

Uses & applications

Commonly used in lapidary arts, jewelry making, and as ornamental stones.

Geological facts

Landscape jasper is highly valued for its intricate patterns that often resemble miniature landscapes, mountains, or trees.

Field identification & locations

Identify by its opaque nature, hardness (cannot be scratched by a knife), and distinct landscape-like patterns. Common locations include the USA (especially Oregon and Idaho), Madagascar, and South Africa.
