GIA Certified Diamonds
The top-rated and foremost authority on diamonds and colored stones in the world is called GIA. 3-6 separate gemologists individually grade each and every diamond for an accurate final grade and GIA receives the grading. Throughout the diamond world, GIA grading reports are considered to be a hallmark of integrity. Two separate types of reports are issued by GIA. The full issued GIA reports is one of the most common reports. It contains the full description of the diamond and a plotting of the grade, setting and also clarity characteristics of that stone. This report is generally used for diamonds one carat and above. For diamonds under one carat the second type of report is used. The full details of each diamond graded can be found in the GIA Dossier. However, in the Dossier, a laser inscription registry number has replaced the plotting which is normally seen on a report. The registry number had been inscribed on the diamond’s gridle so that the stone can be verified without mapping of inclusion. This practice as saved the time and money it would have taken GIA to issue full reports on smaller diamonds.
