The third episode of Rapaport’s GEMTalks series focused on light performance and how it can help determine which diamonds have the most ideal cut grades.
John Pollard, senior director of education at the International Gemological Institute (IGI), and Garry Holloway, inventor of the Ideal-Scope, joined Rapaport’s news editor, Leah Meirovich, to discuss the topic.
Sponsored by IGI, the LinkedIn Live session touched on how light leakage can affect a diamond’s overall fire, scintillation and brilliance; whether light performance was useful for fancy cuts, lab-grown and colored diamonds; and what this metric can add beyond the traditional 4Cs of grading. The guests also answered a variety of thought-provoking questions from the audience.
