Interestingly, as the carat size increases we notice a significant slowing of the surface area. /rebates/2feducation2fdiamond-education2fdiamond-shape2fradiant-cut&252feducation252fdiamond-education252fdiamond-shape252fradiant-cut26tc3dbing-&idwithclarity&nameFour+Mine+Inc&ra3.

Using this formula we can study the corresponding changes in diameter and surface area for a given change in carat weight. Combines the stylish lines of a square or rectangular shape with the brilliance of the traditional round brilliant cut.

For instance, a diamond with a deeper cut will appear smaller than a diamond of the same carat weight with a shallower cut.ДЇor our radiant cut diamond analysis we averaged the diameters of hundreds of thousands to come up with a simple exponential function (shown on the chart below). Combines the stylish lines of a square or rectangular shape with the brilliance of the traditional round brilliant cut.
