Does lab grown diamonds have GIA certified?
Yes. GIA is the abbreviation of the Gemological Institute of America. GIA is an authority in the diamond industry. The certificate issued by GIA is recognized by the industry.Diamonds have always been bought for GIA certificates. Diamonds with GIA certificates are not more secure. Consumers will also be more at ease. Maybe you only know that GIA only issues certificates for natural diamonds, but with the increase in synthetic diamonds, gia not only issues certificates for natural diamonds, but also provides synthetic diamond identification and grading services. GIA has been grading laboratory-grown diamonds since 2007. Beginning July 1, 2019, GIA Laboratory-Grown Diamond Reports and identification reports no longer use the term “synthetic.” The GIA Laboratory-Grown Diamond Report includes the standard GIA color, clarity and cut grading scales for reference purposes.
