Interesting Little Silver Cup with Gold Leaves, 2 Marks & no luck researching

Hello and Good Week end to you all.
I picked this up at an estate sale this morning and thought it was interesting enough to post. My guess is that it's silver, but I may be wrong about that.
It measures 2+3/8" inches in diameter, and 1+3/8" inches high.
I thought it resembled some pieces of Japanese silver that I posted here some time ago, but when I got home and had a chance to look at it with the loupe I saw that the mark doesn't look Japanese at all.
I now think that it may be Russian, but really haven't a clue.
It's a diminutive little cup but has a lot of charm.

Thanks for taking a peep,
Tony.
