Rainbow Petrified Wood Tumbled Polished Rock Arizona
This pretty large tumbled polished Petrified Wood piece is 6 inches by 3.1 inches and 1.3 inches thick and weighs about 1 pound.
It does have some rough areas on the edges and a soft spot in the middle of what I call the back (second picture).
This gemstone is the fossilized wood of trees. The Petrified Wood formed when a tree died and was buried by sediments. Minerals in the groundwater then permeated the wood, replacing the original organic matter and turning it to stone. The main mineral is silica, but trace elements in the silica create a variety of colors.
The most important find in the world of Petrified Wood is in Northern Arizona. The majority of the petrified wood here is Araucarioxylon arizonicum, a prehistoric type of conifer.
This "Petrified Forest" was made a National Park in 1962.
This Petrified Wood is found in the Chinle Formation and comes from the Triassic Period around 220 million years ago.
In Northern Arizona tree trunks as large as 213 feet long were buried under several hundred yards of sediment. Over the course of time the wood was replaced by cryptocrystalline quartz, largely chalcedony and jasper.
Northern Arizona Petrified Rainbow Wood is famous because it is found in so many colors. It is especially known for its reds and yellows.
Of the billions of trees that ever lived, only a fraction were in the right circumstances to fossilize, and only a small fraction of those are solid or have pretty colors or patterns.
In 1988 the Arizona state legislature designated petrified wood the Arizona state fossil.
Metaphysical Properties: Petrified Wood is a stone of patience and slow and steady growth.
