Physical properties
Hardness of 6.5 to 7 on the Mohs scale, earthy to vitreous luster, opaque, and conchoidal fracture with no distinct cleavage.
Formation & geological history
Formed through the slow deposition of silica-rich groundwater into cavities and fractures in sedimentary or volcanic rocks over millions of years.
Uses & applications
Primarily used for lapidary arts, decorative polished slabs, carvings, and unique collector jewelry pieces.
Geological facts
The natural dendrite and mineral patterns often mimic miniature landscapes, tree-like formations, or scenic vistas.
Field identification & locations
Identified by its contrasting gray and tan matrix featuring intricate black dendritic inclusions; commonly sourced from western USA and Madagascar.
