With any diamond, either mined or lab grown, consumers should know what they are buying. True lab 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 lab grown and mined diamonds have identical properties. Both are 100% carbon and thus diamonds. As such, the grading is and should be the same 4C characterization as mined diamonds, with clear representation on the grading report that it is laboratory grown.
Once the lab 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.
