Understanding the Diamond Cut Scale

Before we dive into the excellence of excellent cut round diamonds, let's first understand the diamond cut scale. The Gemological Institute of America (GIA) grades diamond cuts on a scale from Excellent to Poor. The scale includes the following grades: Excellent, Very Good, Good, Fair, and Poor.

1.70ct DIAMOND GIA CERTIFIED ENGAGEMENT RING SOLITAIRE EXCELLENT CUT NATURAL 14K - 10.25

The GIA's cut grade takes into account the diamond's proportions, polish, and symmetry. It's important to note that the cut grade is independent of the diamond's clarity, color, and carat weight - the other three Cs of diamond quality.

Proportions: The Golden Ratio

An excellent cut round diamond adheres to the ideal proportions that maximize light return and sparkle. These proportions, often referred to as the 'golden ratio,' are as follows:

  • Table percentage: 53-62.5%
  • Crown angle: 16-17.5°
  • Crown height: 15-16.5%
  • Pavilion angle: 40.75-41.5°
  • Pavilion depth: 43-44%
  • Culet: None to small

These proportions ensure that light enters the diamond, reflects off the internal facets, and returns out of the top of the diamond, creating a stunning display of brilliance and fire.

Polish and Symmetry: The Perfect Finish

An excellent cut round diamond also boasts excellent polish and symmetry. The polish grade refers to the quality of the diamond's surface, while the symmetry grade evaluates how well the diamond's facets align and mirror each other.

A diamond with excellent polish has a smooth, shiny surface free of nicks, scratches, or other blemishes. Excellent symmetry ensures that the diamond's facets are properly aligned, creating a balanced, harmonious appearance that enhances the diamond's sparkle.
