9.6" Blue, Polished Petrified Wood Round - Arizona

This is an absolutely breathtaking, 9.6" wide polished wood round of Araucarioxylon arizonicum petrified wood from "blue forest" area of the Arizona petrified forest. One side has been highly polished to a glossy finish by one of the top petrified wood polishers around. There are no dull areas or scuff marks on the polished side. It displays a gorgeous blue agate core with red, orange, and yellow coloration peppered throughout the core and rind.

It comes with an acrylic display stand.

This wood is similar to petrified wood found in the Petrified Forest National Park near Holbrook, Arizona. Its petrified forest encompasses nearly 100,000 acres, and is almost entirely represented by the extinct conifer Araucarioxylon arizonicum.

The petrified wood from Araucarioxylon arizonicum happens to be the state fossil of Arizona. It is frequently referred to as "rainbow wood" because of the large variety of colors some specimens exhibit. The reds and oranges come from hematite inclusions within the silica, the yellows from limonite, and the purples from extremely fine hematite spherules.

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.
