This is an interpretation of the famous Celtic Tree of Life. It has interlacing silver branches and roots, with copper leaves, and tiny copper acorns (which occur in threes, a magical number in a lot of ancient cultures including the Celts). The tree itself is an oak tree, the tree of the Druids, and there is a small Celtic Serpent curled at it's base. The Celtic Serpent represented eternal life and rebirth to the Celts.
