Cut is the diamond’s most important characteristic and often is mistaken for shape. Cut describes how well the stone is cut.

Cut is graded as: IDEAL, EXCELLENT, GOOD, FAIR or POOR. “Poor” cut stones are not sold

Symmetry, proportioning and polish and determines diamond’s light reflective properties. The better the cut, the more luminous and brilliant and the more expensive the stone is. Cut gives the diamond its brilliance, its fire, and its scintillation:

Brilliance - The reflection of the bright white light reflection from inside and the surface of the diamond
Fire - The dispersion of light that appears as flashes of rainbow colors
Scintillation - The intense sparkles in a diamond as it moves

Diamonds with poor symmetry and proportions, too shallow or too deep leak the light through bottom and sides and the stone is not as luminous as a to a better grade cut.
