The Ideal Cut
refers to a very limited number of stones. Roughly the top 5% of stones will reach this level of perfection. A diamond that is an “ideal cut” will reflect & shine nearly all of the light that enters it.
The Very Good Cut
refers to a diamond that sits at the top 15% of the quality cut scale. This is a beautiful stone, but the light pattern will be very slightly under the Ideal cut diamonds.
The Good Cut
diamond accounts for ~25% of the diamond market based on their quality of cuts. These diamonds will reflect a majority of the light that enters them, but will be dance less for the eyes than a ideal cut or very good cut.
The Fair Cut
is a quality diamond, but not as brilliant as good cut. With a fair cut, this can mean that the cutter worked to maximize carat weight or to avoid inclusions.
The Poor Cut
refers to diamonds that are significantly out of proportion so as to be much too deep or too shallow cuts. This quality of cut will cause the diamonds to lose light either out of the sides or the bottom of the stone, which will inherently reduce the diamond’s sparkle.
