The most important find in the world of Petrified Wood is in Northern Arizona where the "Petrified Forest" was made a National Park in 1962.
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.
Petrified Wood cabochons from Northern Arizona are known as Petrified Rainbow Wood because it is found in so many colors. It is especially famous 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.
This pretty semi precious gemstone cabochons are from the Conifer tree.
Since these cabochons are actually stone that replaced the wood, they have a hardness of 7, take an excellent polish and wear well.
Petrified Wood found in the Petrified Forest began during the Triassic Period around 180,000,000 years ago.
Petrified Wood is the official State Fossil of Arizona.
