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 recycled 18K gold skull, which measures approximately 3/4" in length and 1/4" in width, hangs on a 16" or 18" 18K gold chain with a hook and eye closure. The skull's eyes are set with two diamonds in the front and 2 diamonds in the back. The approximate total carat weight is 0.42. All diamonds are conflict free.
