IGI’s introduction of Light Performance Grading Reports marks a significant leap forward in diamond assessment, providing a detailed breakdown of key optical characteristics. These reports delve into brightness, fire, and contrast – vital elements determining a diamond’s visual allure – offering both an overall score and individual sub-component scores for each attribute, enabling a thorough evaluation of light performance.
The development of this grading system involved extensive research and analysis by IGI researchers, who leveraged ray-tracing software and slope proportions logic to scrutinize diverse parametric data sets across varying table sizes. This meticulous scientific approach ensures precise and dependable assessment of the optical qualities of round brilliant-cut diamonds.
Furthermore, the incorporation of computer-generated maps and Ideal-Scope images enhances the transparency of the evaluation process, presenting visual depictions of light return, light leakage, and contrast. This facilitates expert analysis and interpretation of the diamond’s light behavior, empowering stakeholders to make informed decisions regarding diamond selection and assessment.
By providing comprehensive Light Performance Grading Reports, IGI aims to assist diamond manufacturers, sellers, and buyers in their pursuit of superior diamonds. These reports not only offer valuable insights into diamond beauty but also equip stakeholders with the knowledge necessary to optimize their diamond-related endeavors.
