Arizona Petrified Wood.

  Petrified wood was formed 225 million years ago during the Triassic period and is 4 times as hard as granite and very colorful, due to the effect of impurities such as iron, manganese, copper and lithium present in the wood during the fossilizing process. This piece has an excellent fine line pattern and will cut some exceptional colorful cabs.   -WET pic.-(10.2 oz)
