Both Gemological Institute of America ( GIA ) and International Gemological Institute ( IGI ), has been grading lab grown diamonds since long. In 2018 Federal Trade Commission recognized lab grown diamonds as real and not synthetic.
From July 2019, GIA lab grown diamond reports no longer use word/term "synthetic" and reports includes standard GIA cutting grade, color and clarity.

Even though both labs are trustworthy and scientific, we believe for today's discerning buyer, IGI certified is the overall better option when buying a lab grown diamond.
