Physical properties
Hardness of 7 on the Mohs scale, earthy to vitreous luster, brown and grey colors, amorphous quartz crystal structure with preserved cellular wood patterns.
Formation & geological history
Formed through permineralization where organic wood material is completely replaced by minerals like silica over millions of years.
Uses & applications
Used primarily for decorative objects, carved display pieces, lapidary art, and collector specimens.
Geological facts
The replacement process preserves intricate cellular details of ancient trees dating back hundreds of millions of years.
Field identification & locations
Identified by its distinctive wood grain texture combined with stone weight and high hardness; found worldwide in ancient sedimentary basins.
