Arizona Petrified Wood
These are brilliantly colored, polished wood bookends of Araucarioxylon arizonicum petrified wood from Arizona. One side has been highly polished to a mirror like finish by one of the top petrified wood polishers around. There are no dull areas or scuff marks on the polished side. Felt placed on the sides and bottom protect your furniture and books. They display a variety of red, black, purple, blue, green and yellow colors that Arizona Petrified Wood is famous for.
The vibrant coloration is due to the contaminating minerals in the silica which replaced the original wood structure. For example pinks and reds are due to hematite, a form of oxidized iron. This is similar petrified would which is found in the Petrified Forest National Park. The petrified forest encompasses nearly 100k acres and this wood comes from land outside of the park.
The petrified wood from the extinct conifer Araucarioxylon arizonicum which happens to be the state fossil of Arizona. The petrified wood of this tree is frequently referred to as "Rainbow wood" because of the large variety of colors some specimens exhibit. The reds and oranges come hematite inclusions within the silica, the yellows from limonite and the purples from magnesium based minerals.
Araucarioxylon arizonicum is estimated to have grown more than 150 feet high and dominated the tropical forests in what is now Arizona nearly 225 million years ago.
