The world’s most acclaimed authority on diamonds and colored stones is called GIA. Three to six separate gemologists evaluate all diamonds individually to obtain an accurate final grade, and GIA is evaluated. Throughout the world of diamonds, the GIA Grading Report is considered a testament to integrity. Two different types of reports are published by GIA. The fully published GIA report is one of the most common reports. Includes a complete description of the diamond and a plot of its stone grade, setting, and transparency characteristics. This report is typically used for diamonds of 1 carat or more. For diamonds less than 1 carat, the second type of report is used. See GIA Dosier for more information on each graded diamond. However, in Dosier, the laser inscription registration number has replaced the plot normally displayed in the report. The registration number was stamped on the diamond griddle so you can see the stone without mapping it to be included. This method saved GIA the time and money it took to publish a complete report on small diamonds.
