GIA icon Tom Moses to retire after 50-year legacy
Legendary gemologist who helped shape global diamond grading standards steps down after five decades at GIA
Tom Moses, executive vice president and chief laboratory and research officer at the Gemological Institute of America (GIA), is set to depart after nearly 50 years of trailblazing service.
Moses spearheaded GIA’s global footprint, elevating it to the pinnacle of gemology and education worldwide, the institute announced last week. He’ll stay on through May’s end to ensure a seamless handover, then transition to chief of gemological research emeritus—a fitting tribute to his indelible mark.

“The rigor Tom infused into grading, the discipline he championed in science, the laser focus on customers, and the humility in leadership embody GIA’s gold standard,” said GIA CEO Pritesh Patel. “His five decades aren’t just tenure—they’re the engine of our explosive growth, fueled by relentless commitment, curiosity, and command.”
A graduate gemologist since joining GIA’s California lab in 1976, Moses climbed through key leadership posts, co-authored over 100 technical papers in Gems & Gemology and peer journals, snagged the 2002 Richard T. Liddicoat Award, and joined the board of governors in 2013.

De Beers – The New Power Move: Why Natural Diamonds Are The Definitive Daily Essential For The Modern Indian Man
Natural Diamonds Are Emerging As the Ultimate Symbol Of Personal Style, Achievement, and Everyday Luxury For India’s Modern Male Consumer.
Masculine style in 2026 has a new focal point. The conversation around men’s jewellery has moved away from traditional ceremonial wear toward a more personal, everyday expression of identity. Whether it is a signature chain, a sculptural pendant, or a bold ring, natural diamonds have become the primary medium for this new aesthetic.
The data confirms this shift: recent industry research shows that 52% of acquired diamonds in India are now worn every day.
This cultural transformation is most visible where performance meets high-profile style. Indian cricketers are leading the charge, wearing natural diamonds both on and off the field as a mark of their personal journey and quiet confidence. From training sessions to post-match press conferences, icons like Suryakumar Yadav, Abhishek Sharma, and Hardik Pandya treat their bespoke diamond pieces as an extension of their professional “armour.”
This ease with luxury is mirrored globally; Formula 1 icons like Lewis Hamilton have long made natural diamonds central to their paddock style, while the red carpet has seen a surge in unconventional masculine styling. Recent appearances by Jay-Z, who wore a vintage diamond brooch at the collar, highlight that natural diamonds are a core part of the modern fashion vocabulary.
The primary driver of this shift is the Gen Z and Millennial male. Broadly the 18 to 38 age group, this demographic is urban, digitally fluent, and possesses a strong personal aesthetic. Gen Z alone now generates 51% of the total natural diamond market value in India, a 19% increase since 2022.
Most importantly, self-purchase is replacing gifting as the dominant entry point. Men are now research-driven and decisive, choosing to buy natural diamonds to mark professional achievements or simply to refine their daily personal brand.
While Tier 1 metros remain the primary base, aspiration is expanding rapidly into Tier 2 and Tier 3 cities. As high-income Indian households are forecast to grow by 16% through 2030, the male natural diamond consumer of tomorrow is younger, more stylistically confident, and far more willing to invest in himself.
This demand is also shaping a new design language. The lone solitaire stud is being replaced by architectural silhouettes, layered chains, chunky bracelets, and rings with clean, geometric lines. Princess and baguette cuts are increasingly preferred for their sharp, masculine appeal.
As we look toward the next decade, this momentum is only set to accelerate. What began as a styling choice on the cricket pitch has matured into a cultural standard of authenticity and permanence. For the modern Indian man, a natural diamond is more than a luxury, it is an enduring signature of his unique journey.
In an era of fleeting trends, this shift toward the rare and the timeless signals a future where masculinity is defined by a legacy that stays forever.
