Pune (Voice news service):- In a landmark event attended by prominent diamond industry
dignitaries and industry leaders, the International Gemological Institute (IGI) proudly
launched its cutting-edge Light Performance analysis — a proprietary innovation developed
by IGI’s Research & Development team. The session was conducted by John Pollard, IGI’s Sr
Director Education, from Dallas USA who was specially flown in for the occasion, the session
underscored IGI’s commitment to going beyond the traditional 4Cs by offering deeper,
science-based insights into a diamond’s optical beauty and brilliance.
The Light Performance provides advanced cut analysis grading technique and is especially
important for diamonds that appear identical on paper – same 4Cs – but differ noticeably in
sparkle and visual presence. For retailers and brands, the Light Performance score enables
clearer product differentiation and storytelling. For consumers, it brings greater clarity,
confidence, and control, ensuring they’re investing in diamonds that deliver exceptional
beauty. This service benefits both the industry and consumers by establishing a consistent
wide-range standard for evaluating and communicating a diamond’s visual performance.
Light Performance reports are available for diamonds which achieve an “Exceptional” score –
whether natural or lab-grown – across IGI’s global grading facilities. IGI will also extend the
Light Performance service to reports previously graded by external laboratories, boosting
their market appeal.
Tehmasp Printer, MD and CEO, IGI stated: “At IGI, our commitment lies in bringing
knowledge and transparency to every diamond we certify. Light Performance analysis
measures what we often refer to as the ‘true beauty’ of a diamond in a quantifiable,
scientific way. By extending our analysis to fancy shapes and flexible report formats, we are
expanding our provision of meaningful information with scientific precision, increasing
confidence for a wider audience of end consumers.”
“Transparency and full diamond analysis are the cornerstones of our work.” Mr. Printer
continued. “Every gem we evaluate – natural or lab-grown – is assessed with same precision
expertise and commitment to quality.”
“Adding Light Performance bridges a gap between the jeweler’s grading loupe and the all-
important eyes of the consumer. In addition to the traditional 4Cs, this report additionally
speaks to the real-world brightness, rainbow flashes and vivid contrast seen during
scintillation – the things consumers love most about diamonds.” stated John Pollard, Senior
Director of Education at IGI, USA.
