HRD Antwerp Certifies World’s First Ring Cut Entirely From Single Lab Grown CVD Diamond

Feb 08, 2019

HRD Antwerp has issued a grading certificate for what it describes as the world’s first wearable ring made entirely from a single CVD lab-grown diamond. The ring has been created by Dutch Diamond Technologies (DD) and has been cut from a single large 155 carat rough CVD lab-grown diamond, which was polished using laser cutting and traditional techniques.

The company has said that the ring, named Project D, took a year to manufacture and was created to mark its 10th anniversary. The ring has 133 facets, compared to 57 for a standard brilliant cut, with a total weight of 3,865 carats.

The grading certificate describes the ring as having the following characteristics: Clarity VVS2, Colour E, Fluorescence NIL, Polish Very Good and Symmetry Excellent. HRD’s lab-grown diamond grading reports are easily distinguishable from the natural diamond grading report by the green colour cover.

HRD said that growing monocrystalline lab-grown diamond plates large enough for such a project only became technically feasible in 2017.

The lab said that prior to this, wearable rings made from a single rough crystal have been manufactured, citing the one made by Swedish jeweller Shawish in 2011. It added that Diamond Foundry has also announced plans to develop a similar ring cut from a single piece of lab-grown rough.

“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.”

“DD might be relatively new to cut diamonds for the jewellery market,” says Michel Janssens, CEO of HRD Antwerp, “but they have created an impressive ring for their 10th anniversary. The outstanding cutting and polish work has resulted in a brilliant light reflection which emphasises the beauty of the ring.”
