Petrified Wood Bookends

With a striking center formation displaying tones of green (one of the most unusual colors seen in petrified wood) these bookends will keep your eyes and your books busy. This pair comes from Madagascar and is approximately 225 million years old. Petrified wood forms when a tree falls and is rapidly buried by sediment such as volcanic ash or river sediments. This creates a reduced oxygen environment (anaerobic) which halts the usual decay process. Minerals carried through the flow of water and absorbed into the tree slowly began to replace the organic material and crystallize. Over hundreds and thousands of years this crystallization took place hardening into stone. Composed mostly of silica (quartz), small concentrations of other elements including iron, carbon and manganese created the beautiful color variations seen here. The front, back, and bottom of the bookends have been cut and polished, with the sides left in their natural state to display the incredible tree bark formation. Displays beautifully from all sides.
