Petrified Wood Board
    Araucarioxylon arizonicum
    Chinle Formation
    Arizona, USA

    During the Triassic, ancient pine trees were buried in mineral-rich material, protecting them from all the destructive forces which should have destroyed them. Through a series of rare and unusual events, that organic wood, in select instances through a process called "capillary attraction," absorbed elements that replaced the natural wood fibers with hard silica (Quartz) cell by cell. The presence of metal salts, along with other elements, resulted in the amazing colors now so associated with this high quality material. It should be noted that only a tiny fraction of all Petrified Wood is of the integrity which can be turned into cut and polished specimens of such beauty and value.
    A large and superb quality specimen of coveted "rainbow" Petrified Wood from Arizona which has been cut and polished is about as good as it can get when it comes to fossils which are truly works of lapidary art. This long board cut can testify to that premise. The tabletop features broad stripes of vibrant colors which transverse the surface horizontally. Swaths of rust orange, violet blue, and mustard yellow sweep across the smooth polished tabletop. Of particular note, the ancient pine tree remnant features a "knot" near the center of the piece which really adds an unmistakable character to the incredibly vivid tabletop.
    Unlike slabs which are slices of longer logs, board cuts go in the opposite direction paralleling the length of the log. Such pieces tend to be larger and thicker carrying considerable weight. This amazing board specimen was treated with a fracture sealer after it was cut then backed with a wood reinforcement and sealed with a fiberglass coating. The tabletop is quite sturdy and, even, scratch-resistant due to the hard Quartz which it contains. This is an example of the finest Petrified Wood available which would make an unparalleled coffee table that could be the centerpiece of most any room.
