Description
Locality: Oregon, U.S.A.
Description: These tumbled picture jasper faceted rectangles from Oregon are cut to emphasize the natural, landscape-like patterns that define this material. Each piece displays layered banding and scenic formations created by mineral impurities, often resembling desert hills, riverbeds, or wood grain. The rectangular faceting adds a clean, structured edge while preserving the organic, one-of-a-kind imagery within the stone.
Oregon picture jasper forms through the silicification of fine-grained sediments such as mudstone and siltstone. Over time, silica-rich fluids permeate the rock, replacing the original material while preserving its natural layering. Iron oxides and other trace minerals create the distinctive color variations and patterning. Deposits in Oregon are known for producing particularly detailed and visually striking material, making it a consistent favorite for lapidary work.
Chemical Composition: SiO₂ (silicon dioxide) with iron oxides (Fe₂O₃, FeO) and clay mineral inclusions
