The natural world is incredibly important in Celtic traditions, and trees especially were intrinsic to their spiritual beliefs. Trees were used to represent the characteristics of individuals born at certain times of the year, a form of Zodiac. Druids would associate the likeness of the trees with the personalities of the people born under their rule. The Celts also believed each month was represented by a precious stone. In the Simon Harrison Talisman collection, our Celtic Zodiac designs combine both the birthstone and its associated Ancient Tree symbol.
