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 round diamonds that are a total of 1/3 Ct. Please let us know your gemstone's carat weight so we can custom make this piece for your stone. This ring usually takes 7-9 business days to complete.
