Polished Blue Forest Petrified Wood Limb (3-1/2 lb)

This is a beautiful section of a petrified wood limb from the "Blue Forest" of Wyoming. This area produces some of the most spectacular petrified wood in the world with deep shades of blues, blacks and tans.

The section of limb is up to 3.7 inches wide and 6.8 inches long, weighs just under 3.5 pounds. Both ends have been polished to reveal the brilliant color of the agatized wood.

This petrified wood was formed when trees died and fell into a swamp where they are rapidly covered by algae. This created casts that preserved the bark surfaces of the trees and kept them from decaying. Over time the algae casts and the areas between them were filled in by minerals forming this beautiful petrified wood.
