Professional tennis player Caroline Wozniacki announced her engagement to pro golfer Rory McIlroy over New Year’s via Twitter and released this picture which shows the happy couple celebrating their New Year’s engagement and a clear shot of Wozniacki’s cushion cut diamond engagement ring which is set in a halo setting very similar to the Allie Halo Setting from Brian Gavin Diamonds. This ring would look amazing set with this 1.678 carat, G-color, VS-2 clarity, Brian Gavin Signature Cushion cut diamond which has an overall cut grade of AGS Ideal-0 on the Proprietary Light Performance grading platform which uses Angular Spectrum Evaluation Technology (ASET)
The purpose of Angular Spectrum Evaluation Technology (ASET) is to measure the brightness of a diamond and to demonstrate how the diamond is making use of the light which is available to it within the room. The red areas which you see within the ASET image of the 1.678 carat, G-color, VS-2 clarity, Brian Gavin Signature Cushion cut diamond pictured to the left, represent the brightest light being reflected by the diamond, the green areas represent the second brightest light, and the blue is the contrast created by the camera lens reflecting off of the eight pavilion main facets located on the underside of the diamond.[separator]
Contrast is a critical factor of diamond cutting because contrast is what enables our eyes to perceive depth within the diamond, which makes the diamond look as if it were sparkling even when it isn’t. For instance, if you work in an office environment which is illuminated with fluorescence lighting, a poorly cut diamond will appear dull and lifeless because fluorescence lighting lacks ultra violet which is required for a diamond to sparkle… however if the diamond is cut to exhibit a high degree of contrast, it will appear to have depth and will look as if it is sparkling even when it isn’t.
Brian Gavin Signature Cushion cut diamonds are cut with an extremely high degree of optical symmetry, they exhibit exceptional contrast and a high volume of light return along with great brilliance, dispersion and scintillation.
