What makes a diamond truly captivating isn’t just its cut, clarity, colour, or carat weight—it’s the way it plays with light. A diamond’s beauty comes alive through three key elements: bright white brilliance, flashes of colorful fire, and the dynamic contrast that creates scintillation. Together, these qualities form the heart of its sparkle.
The IGI Light Performance Report goes deeper than traditional grading. Each diamond receives an overall light performance score along with detailed evaluations of brilliance, fire, and contrast. The analysis is conducted both at close inspection and from a natural viewing distance, providing a complete picture of how the gem performs in real life.
To visually represent this, the report includes a ray-traced IdealScope image—a scientific snapshot proving how the stone interacts with light. This advanced tool is available as a comprehensive report or as an add-on dossier for diamonds graded at IGI or by other institutions.
For retailers and buyers alike, the Light Performance Report is a powerful way to differentiate exceptional diamonds. It combines measurable science with compelling storytelling, giving you the ultimate edge in showcasing what makes a diamond extraordinary.
