The Four C's of Diamonds
C
Color
Fancy colored diamonds range from subtle champagne to vivid pink, blue and green — the rarer the hue, the greater the value.
C
Cut
The cut determines brilliance — how light travels through the stone and dances back to the eye in a fire of color.
C
Clarity
GIA grades clarity from Flawless to Included. Higher clarity means rarer, cleaner stones and greater investment value.
C
Carat
Carat weight measures size and rarity. Large fancy colored diamonds are among the most precious objects on Earth.
