If you have questions or would like assistance in your selection from an experienced GIA diamond grading graduate, call: 1-877-968-7342.
This is the best cut grade assigned by GIA (to Round shapes only) producing the maximum sparkle in a diamond. An excellent (or AGS Ideal) cut diamond has optimal proportions as determined by GIA and thus reflects the maximum light producing the greatest brilliance and scintillation.
This grade of diamond has a minor tint that is barely noticeable especially when mounted. I-color diamond is still in the near-colorless range. In yellow gold, I-color diamonds face-up colorless. Additionally, medium or strong blue fluorescence gives an I-color diamond whiter appearance.
The inclusions in this Slightly Included diamond are easy for a trained grader to see under 10x power magnification. Inclusions in some SI2 graded diamonds may be visible to the unaided eye. SI2 graded diamonds are not as rare thus, more cost-effective than the higher clarity diamonds.
