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. These recycled platinum cufflinks feature our Tibetan skull on both ends with the larger skull measuring approximately 5/8" in length and 3/8" width. Brilliant cut diamonds are set in the skull?s eyes. The approximate total carat weight is 0.68. All diamonds are conflict free.
