It maximizes fire, brilliance and sparkle.

Exactly 100 years ago, a 19-year-old Antwerp engineer named Marcel Tolkowsky perfected a mathematical formula for the 57-facet “brilliant-cut” diamond. Tolkowsky’s accomplishment prevails as the most iconic and successful cut in history due to its ability to maximize a diamond’s fire, brilliance and sparkle.

The Antwerp World Diamond Centre recently held a street fair and ceremonial diamond cutting to honor Tolkowsky and the 100th anniversary.

“In 1919, my uncle Marcel unlocked the secret of light within a diamond,” said Gabi Tolkowsky, one of the world’s most renowned diamond cutters. “He figured out how to get the greatest amount of light to shine out of a diamond, calculating the number and arrangement of facets to maximize the light return. This was Marcel’s gift to the world, perfecting the journey of light, giving all those who came after him the knowledge of how to turn a diamond into a unique beauty.”

Marcel Tolkowsky proved that if a diamond was cut too deep or too shallow, the light coming down from the top would escape out the sides or bottom, resulting in a loss of brilliance. His solution: 57 precisely placed facets cut to exacting proportions so the light coming into a diamond is refracted up through the table and crown to the viewer’s eye.

During the celebration, the AWDC launched its unique “100 Years Brilliant” project, during which 57 well-know (and lesser known) Antwerp residents were invited to polish a single diamond — one person for each facet of a brilliant.

“In this way, ‘t Steentje – which is how the diamond industry is referred to in the local vernacular – will represent the multicultural character and diversity of the Antwerp diamond industry,” explained AWDC CEO Ari Epstein.

Once the stone is finished, it will be exhibited in Antwerp’s DIVA diamond museum.

The first facet was polished by guest of honor Gabi Tolkowsky, who famously spent three years cutting the 273.85-carat Centenary Diamond.

The second facet of the stone was polished by Constantinus ‘Stan’ Hunselmans, who shares his birth year with the brilliant.

“I celebrated my 100th birthday on January 14, and it is an honor that I was chosen,” Hunselmans said. “It went really well. If I were a little bit younger, I might have considered a career switch.”

Since 1447, Antwerp has laid claim to the title of the “World’s Diamond Capital.” It should come as no surprise that Tolkowsky’s brilliant cut was developed in this city.

Thinking of Liquidating? Think: Wilkerson

When Peter Reines, owner of Reines Jewelers in Charlottesville, VA, decided it was time to turn over the “reins” of his 45-year-old business to Jessica and Kevin Rogers, he chose Wilkerson to run his liquidation sale. It was, he says, the best way to maximize the return on his decades-long investment in fine jewelry. Now, with new owners at the helm, Reines can relax knowing that the sale was a success, and his new life is financially secure. And he’s glad he partnered with Wilkerson for this once-in-a-lifetime opportunity. “There’s just no way one person or company could run a sale the way we did,” he says.
