It forms when plant material is buried by sediment and protected from decay due to oxygen and organisms. Then, groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silica, calcite, pyrite, or another inorganic material such as opal. The result is a fossil of the original woody material that often exhibits preserved details of the bark, wood, and cellular structures. We have found the energies that Petrified Wood emanate resonate at a much higher frequency when being channeled outside (especially during the hours of dawn or dusk). Petrified Wood promotes an energetic cleanse and transfer of grounding energy to our physical bodies.
