Unusual silver hallmark, any ideas?

Hello everyone! I hope you are doing well. I collect silver and I found recently a silver ring with gold bezel and tanzanite. It has 2 hallmarks, one 925 and the other I assume is a maker’s mark. Can anyone help me identify it? Sorry if I made any mistakes, first post, new to this forum.
Have a wonderful day everyone.

Any help would be greatly appreciated!
