Then, groundwater rich in dissolved solids flows through the sediment, replacing the original plant material with silicia, 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.
