Hello friends This item I received from a friend who said is original but I want to be sure. It have 14,5 grams

I can tell you confidently that this is not 3rd reich era ring,,meaning it is some kind of postwar thing..

IF you would like to view some 3rd reich rings, jewelry, cufflinks, watch fobs, brooches, etc. have a look here at our own sites 'Honor Ring Forum':
