Bu “ideal” cut grade at Blue Nile is the same as the “excellent” cut grade rating by the GIA

Blue Nile uses the term Ideal while the GIA uses the term Excellent for the highest cut grade in round brilliant diamonds. These two words are interchangeable to represent the cutting style, proportions, and finish necessary to bring out a diamond’s sparkle, brilliance, and beauty.

While the diamond industry has long-standing proportion combinations that optimize light performance, only round brilliant cut diamonds have cut parameters established by the GIA. Blue Nile estimates and assigns cut grade standards for non-round (fancy shaped) diamonds based on their table and depth percentages.

The characteristics of a well-cut diamond are superior brilliance, fire, and scintillation

Brilliance relates to the reflection of white light

Fire is the dispersion of light into the colors of the rainbow

Scintillation is the play of contrast between dark and light areas—it’s the sparkle
