This semi mount features the four "trusses", meeting at surprise diamonds. You see this in the photo below shown with a .68ct Fancy Brown Pink Cushion (not included in the price of this listing) as shown below.
The reason our semi mounts are shown with the center diamonds set into them is simple. We do not keep semi mounts on the shelf. Virtually every ring we make is custom made. That's why the center stone will always fit properly with no gaps. That's why things will always be in proportion.
When looking at our three stone rings, you will notice that the level at which the three stones are set, with the girdles on the same plane. This is virtually impossible to achieve using semi mounts you see in a showcase- shown without a center diamond. Generally the center diamond is set on a "peg head". This type of setting allows a quick delivery – but it also means the center diamond will sit much higher than the side stones.
