Gemological info: Petrified wood is a fossil which is produced when tree-like plants are buried by sediment and is protected from eventual decay caused by exposure to oxygen and organisms. When groundwater flows through the sediment, it replaces the plant with calcite, pyrite, silica, or opa. As a result, the original wood is fossilized. The fossilized wood displays the preserved bark and cellular structures. Petrified wood is often used in lapidary and jewelry.
It eliminates worry and obsessive need to control things that you cannot change. Petrified wood is also an excellent grounding stone; a gem that connects you to your past life. It assists you in coping with a loss or crisis.
