GIA (GEMOLOGICAL INSTITUTE OF AMERICA)
The industry standard of Diamond Grading, all of our diamonds are sent to GIA for certification to ensure that our clients have a independent, professional and objective evaluation of the quality of our diamonds. GIA certification which is used also by major diamond and jewelry houses, starts with the submission of diamonds to their 16 labs (New York, Antwerp, Hong Kong, London, Tel Aviv etc) around the world. These labs are called Windows by trade and the whole process of certification will take about 8-12 weeks. They are submitted with no knowledge of the owners or quality of the stones and only a bar coded label.
The diamonds are graded first by weight and measurements. They are followed by the grading of color in a standard viewing environment to determine color by separate independent graders. Compared to other certification companies, GIA tends to grade a diamond a lower color when the diamond’s color is placed between two grades of master stones. When a stone in question is between an D and a E color, GIA will always practice prudence and grade it lower of the two colors. When there are sufficient agreement on the colors, they will move to Clarity and Finish.
Clarity is graded by a 10X magnification by two independent graders. The first grader assigns his or her initial opinions on the diamond and a second grader does a completely independent grading of the same diamond with no knowledge of the previous opinion. When there is a discrepancy between the two opinions, a senior gemologist will review and issue a final grade on the diamond based on historic precedence or similar diamonds. If the Diamond is a round brilliant, a cut grade will be issued based on the proportions, measurements, Polish and Symmetry of the Diamond. At The Canary Diamond, our cutters will cut the diamonds to the required measurements and finish to ensure that they receive an excellent grade for Cut, Polish and Symmetry otherwise known as Triple Ex in the trade.
