Hi,
Hand engraved.
Kokoshnik (partially struck and assayer`s initials missing) and maker`s mark ending with ``Л`` look OK at first sight. But that`s no proof of authenticity because of suspicious issues:
1. Two marks, one of them being ``900``. The mark on the left needs better close up at the right angle (there are letters to be deciphered, if possible). These marks are not supposed to be found on Russian silver. The ring was not imported to Russia, either; take a look here

Regards
