Frequently Asked Questions​

In the context of diamond grading, “ideal” and “excellent” are both top-tier cut grades, but they come from different grading systems. The “ideal” cut grade is often associated with the American Gem Society (AGS), while “excellent” is used by the Gemological Institute of America (GIA) and the International Gemological Institute (IGI). Generally, both grades signify exceptional quality, but “ideal” is sometimes considered slightly more stringent, focusing intensely on symmetry, proportions, and light performance.

An excellent cut grade diamond is one that has been cut to the highest standards, maximizing its brilliance, fire, and scintillation. This grade, given by grading organizations like the GIA and IGI, indicates that the diamond has ideal proportions and symmetry, allowing it to reflect the maximum amount of light. Excellent cut diamonds are known for their outstanding sparkle and visual appeal.

Both ideal and excellent cut diamonds are among the highest quality cuts available, but there are slight differences based on the grading system.

  • Ideal Cut: Typically associated with AGS, an ideal cut focuses on precision and exacting standards to achieve perfect light performance. It represents the pinnacle of diamond cutting craftsmanship.
  • Excellent Cut: Used by GIA and IGI, an excellent cut also ensures superior light performance and symmetry but may have slightly broader criteria compared to the AGS ideal cut.

In essence, both grades offer exceptional brilliance and fire. The choice between ideal and excellent often comes down to personal preference and the specific standards of the grading laboratory.
