Locket, mystery marks AJ - X (K?) - any help appreciated

[Stickynote]

Hello.

I have a heavy silver locket that I'm trying to date and identify, but I can't figure out the marks at all. I don't know much about silver hallmarks but I've tried to work it out and have checked through the site and the forum but can't seem to find a clear match. I can't even work out which country it's from.

The locket was bought in the seventies, but I don't know any more than that.

Marks are AJ, 925, X (or maybe K?) 925 (bordered by scales).

Any information would be helpful.

I am not too familiar with the European Convention Marking on Imported Items, but it does look like - AJ would be the importer who I can't help with, 925 the fineness mark, X the Assay Office - Edinburgh , the last mark the Common Control Mark.
