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.
E-color diamond is virtually colorless and only experienced graders can detect any color difference between D and E color grades, and then only when they are loose.
The inclusions in this Slightly Included diamond can be visible at 10x power magnification. SI1 characteristics usually are not visible to the unaided eye face-up. SI1 grade diamonds are not as rare as VS and VVS grade diamonds, hence they are less expensive and offer a great value.
