Beschreibung

 

Locality: U.S.A.

Description: These are assorted petrified woods from all over USA- mostly Western. They consist of opalized as well as agatized woods. All are browns, beiges, blacks, etc. Great lapidary material.

Petrified wood is a type of fossil. Wood buried in sediment or volcanic ash soaks up silica from groundwater. The silica coats and fills the cells, so the wood's structure is preserved in stone. The result is a beautiful, often colorful stone that retains the grain and texture of the original wood.

Chemical Composition: SiO2

Grade: Lapidary Grade
Appearance: Opaque
Inclusions: Petrified wood, for the most part, always has cracks. Additionally, some pieces may have weathering and softer rinds- but overall this is lapidary grade wood and pretty good for cutting.

Approximate Size of 1 pc: 13cm x 6cm x 2.5cm 
Approximate Weight of 1 pc: 255g

Rough is rough. We do our best to grade and describe pieces in the lot, but ultimately, they all differ.
