HRD Grades First Lab-Grown All-Diamond Ring

RAPAPORT… HRD Antwerp has graded the first wearable ring
made completely of lab-grown diamond, it claims.

Synthetics producer Dutch Diamond Technologies (DD) created the 3.87-carat, E-color, VVS2-clarity piece from a 155-carat rough chemical vapor deposition (CVD) lab-grown-diamond plate. The company made the ring, called “Project D,” to mark its 10th anniversary. It took a year to manufacture, and has 133 facets.

“We wanted to create something stunning that would highlight
our innovative and high-tech techniques,” Ton Janssen, CEO of DD, said last
week. “I think we’ve more than succeeded with the one-off ‘Project D’ ring.”

The piece is not the first all-diamond ring. In 2011, Swiss
jeweler Shawish revealed a ring made from a single crystal of natural diamond.
Additionally, in December, Sotheby’s auctioned an all-diamond ring made from a
single lab-grown stone. The piece, created by Apple chief design officer Sir Jony
Ive and industrial designer Mark Newson for Diamond Foundry, sold for $256,250, but is still in production, Diamond Foundry said, as it’s making it to fit the buyer’s finger.
