Diamond certificates can be issued with each and every diamond at Wight Diamonds. We use all major grading laboratories such as the GIA, IGI, HRD, EGL (International & USA) & AGS. Diamond certification is an independent opinion of a diamond’s properties. The diamond report, or dossier, includes the diamond’s measurements and defines what the carat weight, colour and clarity are. The cut, polish and symmetry are also graded, along with the fluorescence. More details on each certificating laboratory are given below.
