A diamond’s Color grade refers to the presence or lack of tint in the diamond. Generally referring to a yellow tint.
The Cut is the most objective and scientific measurement of a diamond’s proportions, arrangement and alignment of the facets, and quality of the polish. In an ideally cut stone, the light entering the diamond reflects and refracts creating the fire, brilliance, and scintillation (“sparkle”) in the stone. The Cut is a result of the artistry and craftsmanship of the diamond cutter, to maximize the return of light.
