GIA Calls 4-Carat Solid Lab-Grown Diamond Ring ‘A Significant Milestone’ August 03, 2023 (0 comments)
Carlsbad, CA--The Gemological Institute of America (GIA) recently evaluated a diamond ring cut from a single lab-grown diamond weighing 4.04 carats, deming it “a significant milestone in the world of carved single-crystal diamond rings.”
The single crystal solid faceted ring was evaluated by the GIA New York laboratory.
“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, GIA executive vice president and chief laboratory and research officer. “As technology continues to evolve with man-made diamond growth, we expect to see more creative ways for this product to be used,” Moses said.
The ring was produced by Dutch Diamond Technologies and Belgian jewelry store, Heursel. It was cut from an 8.54-carat lab-grown diamond plate created by chemical vapor deposition (CVD). It consists of a 3.03 mm thick band with an inner diameter of 16.35–16.40 mm and an outer diameter of 20.32–20.40 mm, GIA said.
Gems & Gemology (G&G), GIA’s quarterly professional journal, published an online research note with gemological observations and spectroscopic features. The note will appear in the Fall 2023 print edition of the journal.
