If you do not wish to design a ring from scratch, a semi-mount ring is the option, as it comes partially decorated. While the rest of the ring is pre-adorned, the center stone is of your choice, just like in this ring. The semi-mount engagement ring features a tiered cushion shape center mount, along with a raised prong center, where the center stone of your choice will be installed. This must be a princess cut center stone, ranging from 0.20 carat to 0.30 carat. Accentuating the two lower tiers of the cushion shape mount is 16 prong set round cut diamonds on the upper tier and 24 prong set round cut diamonds on the lower tier. A plain gold shank and a secret pave set diamond each at the front and back of the gallery complete the ring. The semi-mount engagement ring is framed in 14 karat white gold. Total diamond weight is 1/5 ctw.
