Petrified wood forms when a tree or woody vegetation becomes fossilized the matter that makes up the plant is replaced by minerals. Frequently, those minerals are agate, chalcedony, and quartz.
This "agatized" wood carries the properties of agate and chalcedony as well as provides access to past lives through meditation. This stone is ideal for strength in all aspects of your life, grounding, and assistance during periods of crisis or dis-ease by providing insight into the "why" suffering is occurring. This understanding helps you to see the lessons and not repeat them in the future. Petrified wood is also a stone for transformation, helping you to advance to your chosen highest level of growth.
