With any diamond, either mined or laboratory-grown, consumers should know what they are buying. True laboratory-grown diamonds come with a certificate from a reputable gem grading laboratory.
All reputed gem grading laboratories such as GIA, IGI, HRD Antwerp and GCAL among others acknowledge that laboratory-grown and natural diamonds have identical properties. Both are 100% carbon and thus diamonds. As such, the grading is and should be the same 4C characterization as natural diamonds, with clear representation on the grading report that it is laboratory-grown.
Once the laboratory-grown diamond has been graded, the diamond’s girdle is laser inscribed with a unique report number and the accompanying lab report bears a statement that it is a laboratory-grown diamond.
With this direct comparison in the two recognized diamonds, with only difference their origin, consumers can make an educated and fair decision about their diamond purchase.
