African Petrified Wood Agate 8mm Large Hole Round - 8 Inch Large Hole Beads Originally discovered in the 1940’sPetrified Wood Agate is formed from the petrifaction process of primeval trees over the course of many years. Petrification occurs when the wood is covered by sedimentary rock, as waters loosen and decompose the organic elements and replace them with silicate substances, while maintaining the wood's original structure. Preservation is enabled by a lack of oxygen.
