Petrified Wood Coated Stone

This is a beautiful slab of Petrified Wood that has been COATED with a shiny polyurethane coating.

It is 7 inches by 4.5 inches and about .25 inch thick.

It is rough around the edges and has some natural fracture lines.

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.

Petrified Wood is a member of the Chalcedony family. It is very hard and takes an excellent polish, making it a great stone for jewelry.

Northern Arizona is the home of the Petrified Wood Forest, a National Park since 1962. The park sprawls over 346 square miles and is one of the richest troves of the late Triassic Period fossils (210 million years old). It is considered one of the most important Petrified Wood areas in the world. Some logs as long as 213 feet have been found there!
