The cut is made up of various measurements of a diamond's proportions, the arrangement and alignment of the facets, and the quality of the polish, which determine how the facets interact with light.
COLOR
The color grade of a diamond refers to the presence or lack of tint in the diamond. Generally refers to a yellow tint.
CARAT
The carat is a measure of how much a diamond weighs.
