While you can have an engagement ring tailored to your needs, you can also choose from a colossal range of readymade rings. A ring that meets both ways is a semi-mount ring, which comes pre-decorated most of it, except for the center stone, which you can choose as per your liking. This semi-mount engagement ring gives you this option. It features a plain shank and a raised triple mount centerpiece. The centerpiece reveals a slightly raised center mount, which will hold a center stone of your choice. This should be an oval cut center stone in the range of 0.40 ctw to 0.55 ctw. Preset, a prong set triangular cut diamond each on lower raised mounts, flanks the center mount on either side. The semi-mount engagement ring is styled in a polished rhodium finish 14 karat white gold. Total diamond weight is 1/4 ctw.
