IGI certificate for a lab-grown diamond – sample

Sample IGI certificate

This is what the IGI (International Gemological Institute) certificate you receive with every lab-grown diamond looks like. It states the carat weight, colour, clarity, the cut, polish and symmetry grades, the exact measurements and the laser inscription on the girdle, by which the stone can be verified at any time.
