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.
H-color diamond appears white when mounted in either white or yellow gold and platinum setting. Thus, this grade of diamond offers an excellent value in the near-colorless range.
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.
