DDT creates an entire lab-grown diamond ring

08 february 2019

Dutch Diamond Technologies (DDT) has created a ring that is entirely made from a lab-grown diamond, says HRD Antwerp.
It took the company one full year to manufacture the ring «Project D», which was created for the DDT’s 10th anniversary. 
HRD Antwerp will grade the lab-grown diamond ring made of 155 carat rough CVD lab-grown diamond, says the report.

“For our 10th anniversary we wanted to create something stunning that would highlight our innovative and high-tech techniques,” says Ton Janssen, CEO of Dutch Diamond Technologies. “I think we’ve more than succeeded with the one-off ‘Project D’ ring. It’s a true “European” ring: grown in Germany, cut in the Netherlands and graded by HRD Antwerp in Belgium. HRD Antwerp has a well-earned reputation for delivering a perfect grading system thanks to their sophisticated equipment and dedicated team.”
The ring is reported to have 133 facets and weight 3,865 carats.
Previously it was reported that the Diamond Foundry together with the world’s leading designers – Jonathan Ive and Marc Newson – created a unique ring completely made of diamond with about 3,000 facets.
It is only recently that the technologies made it possible to grow such big synthetic pieces to carve a full ring out of it.
