Large empty pocket or dish in petrified wood

Empty pocket or dish in petrified wood. Petrified wood is a wood fossil (same family as magnolia) dating back 20 million years. Silica replaced the wood fiber molecule by molecule, giving silicified wood. Fossilization is slow, which makes it possible to distinguish the patterns of the trees. Petrified wood is a noble material that lies between granite and precious stones. Feel free to contact me for more information. Height: 2cm; width: 25cm; length: 29cm.
