Choosing a semi-mount engagement ring helps if you wish to select a center stone of your liking for it. As the name suggests the ring comes partly embellished, with the center stone left for you to choose. This semi-mount diamond engagement ring is an elegant option. It features a plain white gold shank, with a triple mount centerpiece raised above the shank. Of the triple mounts, the one in the center is taller than the mounts on its either side. This taller mount is where the center stone of your choice, which in this case must be round cut in the range of 0.40 ctw to 0.55 ctw, gets installed. The part of the ring that comes pre-decorated is the two smaller mounts, each of which is embellished with a pear cut diamond, 2 in total. The semi-mount engagement ring is styled in 14 karat white gold. Total diamond weight is 1/4 ctw.
