I recently picked up a nice looking silver ring that appears to be a designer piece, not sure of the age but if the style is any indication then I would guess that it is pre-1950 at least. It’s a very interesting item since there is a heart shaped pendant attached to the top center of the ring that moves back and forth. One side of the heart appears yellow gold toned and the other side is silver, both sides are set with six stones -guessing these are diamonds.

You can clearly see the figures 925 over 750 on the interior of one side of the band. The other interior space of the band shows a mark and a signature. The signature looks like it has double-lls in the name, maybe first name is Felix or Paul, and last name is something like Gillon or Fuller. I can’t make heads or tails off the mark. Anyone know about this very unique piece?

Thanks for looking, and any information would be terrific!
