GIA Examines All-Diamond Ring Cut From Single Lab-Grown Diamond

It’s the first time the lab has assessed a piece of this kind, it said.

Carlsbad, Calif.— The Gemological Institute of America’s New York laboratory recently evaluated a single-crystal all-diamond faceted ring made from a lab-grown diamond.

Produced by Dutch Diamond Technologies in collaboration with Belgian jewelry store Heursel, the 4.04-carat ring was cut from an 8.54-carat lab-grown diamond plate created by using the chemical vapor deposition (CVD) process. 

The band is 3.03 mm thick with an inner diameter of 16.35–16.40 mm and an outer diameter of 20.32–20.40 mm.

GIA said its development marks a “significant milestone in the world of carved single-crystal diamond rings.”

“Although this is not the first ‘ring’ of this type that has been reported, it is the first time GIA has evaluated a ring carved from a single laboratory-grown diamond,” said Tom Moses, executive vice president and chief laboratory and research officer at GIA.

“As technology continues to evolve with man-made diamond growth, we expect to see more creative ways for this product to be used. New achievements will advance the bounds of what is possible with laboratory-grown diamond, both in new applications in jewelry and technology.” 

GIA published gemological observations about and spectroscopic features of the ring in an online research note.  

The research note also will appear in the fall 2023 print edition of GIA’s quarterly professional journal, Gems & Gemology.
