This parameter refers precisely to the color of a diamond.
The color range of diamonds varies from ice white to warm white. Diamonds are classified according to a scale established by the Gemological Institute of America (GIA) which goes from D (colorless) to Z. The colors shown in the table are only to show the differences in shades. The letter D refers to perfectly colorless stones, the rarest and most expensive. Below we have the color E (exceptional white), F (extra white +), G (extra white), H (white), I-J (slightly tinted white), K (tinted white). M-N-O-P-R-S-Z (colorito).
