Petrified wood is formed when a tree completely transforms to stone as all the organic material gets replaced by minerals. This process is called peri-mineralization. The petrifaction takes place under the ground when the wood gets buried under sediment and this process can take millions of years. The result is a very strong material with the structure of wood. The color is determined by the type of mineral. Depending on the predominant minerals that seeped with the cell structure of the wood, petrified wood has different colors ranging from subtle browns to vibrant blue-greens.
