Quite right, this is the monogram of Emperor Nicholas II.
In the Russian Empire, there were rather complicated rules for using the sign of the ruling monarch. In order to publicly wear this sign, it was necessary to have the permission of the Emperor himself and to comply with many requirements. But army and navy officers sometimes ordered signs to jewelers and wore them outside of official service. Especially far from both Imperial capitals
