The Half Round Dome Shape of this Ring Is the Most Popular shape in Wedding Bands. Because of manufacturing difficulties in making this kind of Wedding Band, and because it takes more silver to make it, it is only found in finer stores. This Ring is little more less than 3/16" (4mm) thick, and has a Very Nice Solid Feel to it. And because it's all hand polished (no plating), sizing and engraving of this ring is no problem ©.
