cut | ˈkət
A term which refers to the geometric proportions that dictate the reflection and refraction of light within a stone
Cut is perhaps the most important factor in determining the value of a diamond or gemstone. The brightness, or brilliance, of a diamond is assessed by the amount of light that is emitted into a person’s eyes. Furthermore, light makes an entrance into the stone via the crown, the area of the diamond that is located above the girdle. The “Diamond Cut” precisely makes reference to the quality and overall condition of a diamond’s primary features, including but not limited to: proportions, angles, brilliance, scintillation, symmetrical facets, fire, and finishing details. These features significantly influence the diamond’s shimmer, in addition to its overall beauty. The Gemological Institute of America assesses a diamond’s cut by “Ideal”, “Excellent”, “Very Good”, “Good”, “Fair” and “Poor”. Depending on the diamond’s shape, the grades “Ideal” and “Excellent”, are evidence of sizes and gradients cut for the utmost shimmer and zeal.
