5.8" Petrified Wood (Spruce) Limb Section - Eagle's Nest, Oregon

This is a beautiful polished limb section of Miocene aged petrified wood (Spruce) collected near Eagle's Nest, Oregon. It's 5.5 x 4.4 inches and up to 5.8 inches thick/long. Both ends have been cut flat, one of which is beautifully polished so you can see all of the detail including the tree rings. It was polished by one of the best in the business, so there are no scuff marks of dull spots.

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
