Thank you all :
This ring is probably an easier one to identify , the engaving lettering , date and 0 , I was convinced of it being a copy .There are other Rings with those errors too.And some good copies I mostly likely would get cought on .
Correctly said , the document could be good .However only an actual hand inspection by an expect in the document field would be only 100% acurate .More and more places are offering laser copies with undistinguishable quality on correct paper etc,etc ...that will fool 'experts' ! Scarry world out there .
