Below is some information about the semi mount setting. What are Semi-Mounted Rings? Preset rings are completely finished when you first view them, and custom rings entail significant work before you get the design you envisioned. Semi-mounted designs bridge the two by carrying a fully designed ring and setting while allowing buyers to customize the center diamond. There are many metal hues available under semi-mounted rings, with some of the styles including oodles of details and diamonds, while others settle for the simple elegance of a solitaire, and nothing more. Couples can choose from among halos, bezel settings, and side stones, and each of these options is customizable to fit their center stone of choice. The last bit offers a level of flexibility in terms of cost that most buyers working from inside a budget see as a blessing, which it is. It also affects the personality of the stone, which is something many people overlook. Semi-mounted rings bring a customized look for lower price, which makes one worth buying.
