Vintage Long Sterling Ring, buying Unusual Sterling Ring, Vintage Sterling Jewelry, Etched Sterling Ring

Unique long sterling silver ring has a domed bead center with an overlaid dome rectangular piece set over it. The overlaid element has unique etched designs and has a sort of faux small bead border. Ring is about 1 1/10 inch long and slightly over 1/2 inch wide. It is signed on the underside and is very hard to see as there is a textured design on the underside. I can read Morrocco 925 and there looks like an "A" or triangle before that. I will try to get buying a better look and update.
