As those dealing in Brown are very much aware of C1 to C7 color scale
We grade Light Champagne Brown Diamonds (C1 & C2) as Natural Fancy Very light Brown & Natural Fancy light Brown respectively. If they are Medium Champagne Brown Diamonds (C3 & C4) we grade them as Natural Fancy Medium Brown & Natural Fancy Brown respectively. If they are Dark Champagne Brown Diamonds (C5 & C6) we grade them as Natural Fancy Intense Brown & Natural Fancy Vivid Brown. If the Diamond is Fancy Cognac i.e. C7 we grade them as Natural Fancy Deep Brown. We also grade C8 if the Diamond's color is Fancy Very Rare Cognac as Natural Fancy Vibrant Brown.
Color Hue:
Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid and Fancy Dark are fancy grades representing the combined effect of tone and saturation on a certain hue. These fancy grades vary in intensity, in different hues since the highest saturation levels are reached in different levels of tones according to the hue. This phenomenon is apparent when one examines the asymmetrical appearance of the makeup of color space.
The Color Hue, which we are aware of in most cases, is Fancy Orange Brown (Mix tone or Hue of Orange & Brown). Fancy Pinkish Brown (Mix tone or Hue of Pink & Brown). Fancy Brownish Greenish Yellow (Mix tone or Hue of Brown,Green & Yellow). Like wise the grade is given as per the Hue or tone present in the Diamond.
Now for E.g.:
If our diamond is C7 i.e. Natural Fancy deep Brown with orange and red hue or color tone from face up. We will grade it as Natural Fancy deep reddish orangish Brown.
