If you want something done right...do it yourself.

I don't like a big writing and I fear that the customers don't appreciate it :thumbsdown

I try to propose a solution with a modified picture (2 alternative solutions).
I tried to write "copy" near the ring in circular manner (but may be difficult for the engraver) and to the bottom.

The writing "Mulyazh" I think must be in Cyrillic translation that may be more difficult for the engraver. Someone can translate the writing?
May be a Latin writing like "Copy" is better, because for the future one people may think that the cyrillic writing indicates a special production with a higher value
