just waiting for you to put the ring down while you go and 'think about it' .
Quickies for authentication:
-Look for stamped in hallmarks..
-If an enamel ring,,test it! , after you ask permission
first of course!!
-Look for seam,,look for faults: - lines, dots etc.
-A top view,,,nice thin rear of band? nice and even too?
Know your materials,,Zink , Brass, try and see the difference between Sterling and 800 ,yes super hard to do,,,,but what else you got to do!
