Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy luster, opaque, displays intricate banded patterns resembling landscapes.
Formation & geological history
Formed through the deposition of silica-rich mud or ash in ancient basins, with patterns created by trapped mineral solutions.
Uses & applications
Used primarily for ornamental items, cabochons in jewelry, and prized by mineral collectors.
Geological facts
The distinct scenes and landscapes seen in the stone are actually dendritic patterns of iron or manganese oxides.
Field identification & locations
Identified by its distinctive earth-toned banding and conchoidal fracture; commonly sourced in the western United States and Madagascar.
