A few days ago, a friend sent me a message on WhatsApp asmall post announcing that he is selling lab-grown diamonds. That caught my attention and started thinking how the whole landscape changed from those times I worked in worldwide diamond. Even Ten years ago, this would have sounded likescience fiction. Today, it’s simply the new reality of luxury.
I couldn’t help recalling the words of, Mr. Luc J. Cleas,who during those opening sessions of training programs said, “Diamonds are for everyone.” When he said it almost three decades ago, he meant efficiency better yields, leaner operations, and affordable stones for more people. But standing in today’s world, those words carry a different resonance.Diamonds truly are for everyone now. Not just because they are accessible, but because technology and shifting values have redrawn the very idea of brilliance.
Technology and the Art of Light
Among all transformations, none excites me more than theevolution of the Tolkovsky cut my lifelong fascination.
When Marcel Tolkovsky in 1919, calculated the precisegeometry for maximum brilliance: 58 facets, each tuned for perfect light return. His formula shaped a century of craftsmanship.
We once relied on instinct and loupe; now brilliance itselfis data-driven. Yet, the poetry remains the same brilliance is still about understanding how light behaves inside a human idea of beauty.
The Lab-Grown Renaissance
If technology redefined cutting, it revolutionized creation.Lab-grown diamonds (LGDs) once reserved for industrial drills are now centerpieces of engagement rings and ethical luxury.
By 2024, LGDs made up roughly 25 percent of globaldiamond sales by value
Their prices, once only 20 percent below naturals, now standat nearly 80 percent less. That affordability, coupled with ESG appeal, has opened new markets among young and design-conscious buyers.
Geopolitics of Brilliance
The diamond story is inseparable from global politics. U.S.and G7 sanctions on Russian diamonds notably from Alrosa, which contributes about 30 percent of world output have redrawn supply routes.
Botswana and Angola are reclaiming value through localbeneficiation, while Dubai has emerged as a trading nexus between continents. Even Antwerp has changed, enforcing strict cash-transaction limits and compliance standards. Transparency is no longer a virtue it’s survival.
The Digital Revolution of Trust
The pandemic accelerated a shift that was already underway: the digital diamond trade.
Virtual showrooms, AR fittings, and blockchain verificationhave made it possible to buy brilliance with a click and trust it. The handshake has evolved into a digital ledger, but the sentiment remains timeless: trust, verified.
What the Stone Still Teaches
After two decades of watching this industry evolve, I’vecome to see diamonds as mirrors of civilization enduring yet ever-changing.
From Antwerp’s vaults to Indian cutting hubs, from De Beers’monopoly to blockchain marketplaces, every transformation tells the same story to catch light differently, you must change your angles.
The art of brilliance has never been about hardness. It hasalways been about perspective about the willingness to be refined, again and again, until light finds its way through.
A Final Reflection
Mr. Luc’s words “Diamonds are for everyone” havefinally come true, though in ways none of us imagined.
In today’s world, brilliance is not confined to mines ormachines; it’s defined by values, transparency, and imagination. Thediamond’s greatest transformation is not optical it’s ethical.
In that sense, the industry has found its finest cut yet.
