(PRESS RELEASE) CARLSBAD, CA — The Gemological Institute of America (GIA), the leading institute for research into diamonds, colored stones and pearls, recently evaluated a diamond ring cut from a single laboratory-grown diamond. The unique 4.04 ct single crystal solid faceted ring was submitted to the GIA New York laboratory for assessment, marking a significant milestone in the world of carved single-crystal diamond rings.

Gems & Gemology (G&G), GIA’s quarterly professional journal, recently published an online research note with gemological observations and spectroscopic features of this rare laboratory-grown diamond ring. The research note will appear in the Fall 2023 print edition of the journal.

The ring, produced by Dutch Diamond Technologies in collaboration with Belgian jewelry store Heursel, demonstrates the fusion between cutting-edge technology and traditional craftsmanship. It was cut from an 8.54 ct laboratory-grown diamond plate created by chemical vapor deposition (CVD). The 3.03 mm thick band had an inner diameter of 16.35–16.40 mm and an outer diameter of 20.32–20.40 mm.

“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. 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,” said Tom Moses, executive vice president and chief laboratory and research officer at GIA

Wilkerson Testimonials

Wilkerson: “They Feel Like Family”

Newton’s Jewelers in Fort Smith, Ark., was a true institution. But after being at the helm for most of his life, owner (and descendent of the original founder) Kelly Newton decided it was time to retire. He chose Wilkerson to handle the sale. “I’ve known the owners of Wilkerson for a long, long time. I felt at home with them,” he says. The final retirement sale was just a “blast” and the Wilkerson sales team made it so very simple and straightforward, says Newton. Would he recommend Wilkerson to others? Absolutely. “They’ve done incredible work,” says Newton. “They feel like family.”
