Antonio has undertaken a serious in-dept study on these rings, and backed it up by scientific evidence to show the same. Time and again he has demonstrated a multitude of casting flaws and dependencies and explained how each vary, from ring to ring. On the other side of the discussion there has been nothing: no manufacturing evidence, no answers to Antonio's questions when asked, no lab scope study, no ring composition study, no experts in the science world, or no jeweler expertise. The die press proponents have presenting nothing other than: "they are die pressed or die struck, because I said so". OK, show us how these rings can be manufactured under striking or pressing, and explain the reason why every single example is different?
