Star129 Diamond is the first diamond ever to guarantee the highest rating possible for scintillation. How is this achieved? When we are cutting a Star 129, we assess each individual diamond and hand-select only the best to create an ideally cut diamond. We have increased the number of facets to maximize the beauty of the diamond without compromising the refractive properties. The facets of a diamond are an arrangement of prisms and mirrors. A traditional 58 facet diamond has sparkle, but the majority of the sparkle is on the outer edge of the diamond and not underneath the table of the diamond, causing it to lose some of its brilliance. The Star 129 adds 71 additional facets to the bottom of the diamond and by adding these facets we have more than doubled its ability to reflect and refract light, significantly enhancing the diamond’s light performance. Our master cutters have informed us that the Star 129 is the most challenging diamond they have ever cut in their careers! They estimate that it takes almost three times as long to cut a Star 129 diamond as it does a standard diamond.
Every Star 129 diamond comes with a traditional diamond grading certificate from GIA or EGL, as well as a Gemex Three Dimensional Light Performance Report that shows how well each diamond performs for the light. But the most important instrument in measuring beauty are your own eyes, and the Star 129 creates a difference that can be seen with the naked eye. No special lighting or magnification is needed. We encourage you to compare Star 129 to any other available round diamond on the market, we guarantee you and your friends will see a difference! As to which diamond you choose for your purchase, our advice is to trust your eyes and let them be your guide.
Gemex measures the three components of sparkle:
- White Light (Commonly referred to as brilliance.) The BrillianceScope Analyzer measures the percentage of the diamond returning bright white light to the observer.
- Colored Light (Commonly referred to as fire.) The BrillianceScope Analyzer measures the percentage of the diamond returning bright colored light to the observer.
- Scintillation (“Scintillation is the term used for changing colors, the radiance and sparkle of the rays when the stone is moved or when the light source changes.” DIAMOND GRADING ABC, Varena Pagel-Theisen.) The BrillianceScope Analyzer measures the number of light points and determines how they change from position to position.
