The skull is a reminder that all things will pass, that there is wisdom in living in the face of such mortality, and therefore, we should live fully and mindfully. This tiny recycled 18K gold skull charm is set with two diamonds on the front and 2 diamonds on the back, and hangs from a 16" or 18" 18K gold chain with a hook-and-eye closure. The skull measures approximately 1/2" in length and 1/4" in width. The approximate carat weight is 0.1. All diamonds are conflict free.
