As shown with a 1.08ct Y-Z, Natural Light Yellow Branded DBL Old Mine Brilliant Diamond (not included in the price of the listing). On this particular example, the setting has 65 E-F VS single cut diamonds for a total weight of .44cts.

This ring is shown with the optional single cut melee. In this ring are 65 Single Cut diamonds of varying size. Literally - the sizes range from .7mm up to 1.4mm. Let me tell you- this many single cuts working together is very cool. The sparkle is definitely different than full cut diamonds.

What is a "Single Cut"?

When smaller diamonds were first polished they were even simpler than the Single Cut. The diamond is divided by 8 on top and bottom- with a large flat facet on top called the "table".

Here's the basic facet pattern of a single cut diamond

Looking through the diamond you see something like this

This design is the foundation for every Modern Round Brilliant. Below I've sketched in the additional facet lines that give the Modern Round Brilliant diamond 57 facets, versus 17 for the Single Cut.

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.

Where is this ring made?

This ring was manufactured in New York City.

To achieve these results, you need a combination of things. A highly skilled workforce is only the starting point. Specialized tools are required. The reason that the parts join together so well is because the parts were designed, and polished using a microscope..

The methods used for welding involve working in as sterile an environment as possible- while focusing acutely on specific areas using a microscope. This comes into play heavily on a ring of multiple metals, such as this one.
