Petrified Wood is a fossil in which the organic remains have been replaced by minerals in the slow process of turning to stone. This petrification process generally results in a Quartz Chaledony mineralization. Special rare conditions must be met in order for the fallen wood to be transformed into precious Fossil Wood or Petrified Wood. In general, the fallen trees get buried in an environment free of oxygen (anaerobic environment), which preserves the original tree structure and general appearance. The other conditions include a regular access to mineral rich water flowing through the wood, replacing the organic tree structure with inorganic stone. The end result is Petrified Wood, a tree, with its original basic structure in place, replaced by stone.

This is a really great specimen with lots of variety of mineral inclusions
