The Gemological Institute of America (GIA) has graded a 5.01-carat lab-grown diamond that, its producer claims, is the largest pink synthetic diamond in the world.
New York-based Unique Lab Grown Diamond created the stone using chemical vapor deposition (CVD). The square-radiant-shaped, fancy intense pinkish-orange synthetic stone has the equivalent of SI clarity, the GIA said in a lab note last month.
The lab-grown stone showed some “outstanding gemological features,” the GIA noted. “The combination of size, color and clarity make this the most remarkable CVD synthetic diamond the GIA has tested so far,” it added.
