Blue Forest Petrified Wood Slice (3 inches)

This is a beautiful slice of 50 million year old petrified wood from the famous "Blue Forest" in Eden Valley, Wyoming. It was formed when trees died and fell into a swamp where they are rapidly covered by algae. This formed casts that preserved the original bark surfaces of the trees and kept them from decaying. Eventually the algae casts and the spaces between them were filled in by minerals, often in exquisite, crystalline form.

This colorful slice of petrified wood has been highly polished on one side, by one of the top polishers out there. It doesn't have any of the tool marks or scuffing that might be left by lesser quality polishers.
