I love Green Petrified Wood! I find that the Green Petrified Wood connects with my higher heart and has an expansive, loving energy, as opposed to the brown wood which tends to have a more gentle grounding energy. When I work with this crystal, I feel so much love and gratitude for mother earth, nature and all of creation.

Petrified wood is also known as fossilised wood. It is formed when a tree or tree-like plant changes to stone by the process of permineralization. I have taken this paragraph from Wikipedia as it best explains the process:

“Permineralization, a type of fossilization, involves deposits of minerals within the cells of organisms. Water from the ground, lakes, or oceans seeps into the pores of organic tissue and forms a crystal cast with deposited minerals. Crystals begin to form in the porous cell walls. This process continues on the inner surface of the walls until the central cavity of the cell, the lumen, is completely filled. The cell walls themselves remain intact surrounding the crystals”.

In petrified wood, the mineral in the stone is usually a silicate, such as quartz. It comes in many different colours, depending on the tree that it was originally created from and the minerals in the water as it was forming.
