Petrified wood is formed when a mineral, usually Agate, replaces the wood of ancient trees. Under the right conditions the rotting wood is replaced, atom by atom, with crystals of fine Quartz or Agate, creating a perfect copy of the tree in stone. Fossilized or Petrified Wood retains its original shape and structure, even its growth rings, knots and patterns.
Petrified Wood is used in magic to create a deep connection and broad understanding of trees, considered by some magic users to be the kings of the plant kingdom. It is a very useful crystal for anyone interested in Celtic Tree Lore and the ancient 'Tree Calendar', which was used by Northern European tribes to mark the passing of the seasons. The stone is said to preserve the energetic patterns of the tree whose form it has taken. It is widely believed to be a stone of roots and beginnings, used to draw strength and knowledge from the ancestor spirits that can be used for practical purposes in the modern world.
Petrified Wood is used to encourage past life memories and communication with souls from the past. In meditation it can be helpful for finding out who and what you really are, showing you the lineage you belong to and the destiny you are fated to achieve. Petrified Wood is said to develop the powers of instinct and intuition so that you can understand the lessons of history and the stories of great teachers and powerful people who came before us.
