Buying GIA Diamonds
Over 60 years ago, the GIA revolutionized the diamond industry with the GIA Diamond Grading Report. When you buy a GIA diamond, you can rest assured that it has been certified according to the strictest criteria and by the world’s foremost authority on diamonds.
The GIA Diamond Grading Report contains a comprehensive analysis of a diamond’s quality (Diamond 4Cs) and lists information about the particular diamond’s shape and cutting style; measurements; carat weight; clarity, color, and cut grades; finish; fluorescence; and any other comments that are relevant to the diamond. While a number of other laboratories, such as IGI or EGL, issue similar reports, the GIA has established a reputation for providing the utmost precision and integrity when grading diamonds.
