GIA Diamond Certification

At Simon Alexander, all diamonds available for sale are graded and certified with GIA (Gemological Institute of America).
This is the world's highest, most renowned source for Diamond Grading and Certification.

GIA certified diamonds are laser inscribed on the girdle of the diamond with their report number.
This gives you the peace-of-mind, knowing that your chosen diamond corresponds to the correct Grading Report/Dossier.

With the purchase of a GIA certified diamond through Simon Alexander, we offer a complimentary in-store viewing of the laser inscription with one of our friendly Diamond Specialists. This occurs both when the diamond is loose and again after the setting process.
