This is a slightly smaller (and less expensive) version of my Sephirot Pendant.
In both Kabbalah and western alchemy, the Sephirot, or the Tree of Life, is a metaphysical object that represents many things: man as both a divine and mundane being, the universe, and life itself. It is typically represented geometrically in this pattern, though many variations on it have been used throughout history. The ten sephirot, the junctions of the tree's branches, are each labeled with a Greek celestial symbol representative of each nexus' place in the tree. The empty sephirot (Da'at) is represented in the middle of the pendant by interlocking toroids.
