You need not buy a readymade engagement ring, as customization is possible. A semi mount ring is perfect in this aspect as it lets you have a center stone of your choice put in. This engagement ring has the dazzle and charm of a fully ready ring, except for the center stone that you will add to it, which can be in a range of 0.25 carat to 0.35 carat. What is more, it comes preset with 18 dazzling prong set round cut diamonds lining the shank in a neat sparkling row. The ring is designed in 14 karat white gold. Total diamond weight is 1/3 ctw.
