A semi-mount is a ring that does not yet have a center stone. With a semi-mount ring setting, you can choose the center stone, including the cut, carat weight, and more. This lets you select a band that captures your partner?s style and find a stone just for her. This is also an excellent option if you have an heirloom diamond or gemstone that you want to use. A semi-mount engagement ring is the perfect choice if you want flexibility in choosing the ring but still need a little direction. This diamond engagement ring is manufactured from 2.0 grams of solid and real 14K white gold, not plated, not filled. The diamonds are I/J Color, SI2/I1 clarity. On the sides there are 1.30 mm smaller round diamonds that are a total of 1/3 Ct. Matching band can be manufactured upon request. Please let us know your gemstone's measurements so we can custom make this piece for your stone. We can make this ring in all yellow or rose gold too for the same price. This ring usually takes 7-9 business days to complete.
