Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy luster, opaque, and features distinctive banded brown and tan landscape patterns.
Formation & geological history
Formed when silica-rich groundwater permeated fine-grained sediment or volcanic ash, solidifying over millions of years.
Uses & applications
Widely utilized in decorative objects, cabochons, lapidary art, and metaphysical crystal collections.
Geological facts
The unique scenery-like patterns are caused by trapped iron and mineral oxides flowing through the silicate matrix during deposition.
Field identification & locations
Identify by its distinct landscape-like banding and conchoidal fracture; commonly sourced from arid regions like Oregon and Madagascar.
