Physical properties
Hardness of 7 on Mohs scale; colors include brown, yellow, and red; waxy to vitreous luster; amorphous crystal structure replacing original organic cells.
Formation & geological history
Formed via permineralization, where groundwater rich in dissolved silica replaces organic plant matter over millions of years.
Uses & applications
Used primarily in lapidary arts, decorative items, high-end jewelry, and as collector specimens.
Geological facts
The petrification process can preserve microscopic cellular structures of ancient trees dating back hundreds of millions of years.
Field identification & locations
Identified by its distinctive wood grain patterns combined with high hardness and stone-like weight; commonly found in ancient floodplains and volcanic ash deposits.
