The GIA report
Each diamond is unique with its own, very distinct characteristics! To make the best purchase, you must know all the details of the stone. At St-Onge, all our diamonds are sold with a certificate issued by theGIA. The GIA (Gemological Institute of America) is the most renowned laboratory in the world for the classification of diamonds and the identification of precious stones. Our Lab Grown diamonds are sold with a certificate issued by the IGI (International Gemological Institute).
Both GIA and IGI reports give the complete description of the diamond, including its colour, its weight, its dimensions and its cutting style. The report number is engraved on the diamond girdle.
