Metanoia is Greek for the changing of ones heart, or spiritual transformation.  We don't think of skulls as symbols of death, but rather a transformation, or spiritual transition from the physical plane to the spiritual.  One must overcome the fear of death and the fear of what's beyond to truly grasp who they are, and what they are not.  This Ring is a symbol of that process.  Comes in Silver, silver with gold accents, Silver with gold and diamonds, or solid 18k gold and diamonds.
