GIA Colored Diamond Certificate Sample
Hue (Hue) represents the main color and secondary color contained in a colored diamond. For example, a pink diamond with brown color will be called Brownish Pink, with the secondary color in the front and the main color in the back. This kind of color ranking has a very significant impact on the value of colored diamonds. If it is also a brown diamond, and the color ranking becomes Pinkish Brown, it means that the diamond is a brown diamond rather than a pink diamond. Everyone should remember this.
Tone represents the expression of color from light to dark, very light color is called Faint, and very dark color is called Fancy Dark. Note that colored diamonds do not necessarily have a high quality if they are dark in color. If the color is too light or too dark, both the visual appearance and the value of the diamond will be greatly reduced.
Saturation represents the concentration of the color. Only when the color depth reaches the Fancy level, GIA will add the color intensity to the rating range. Don't confuse color intensity with color depth. The former represents the lightness and darkness of the color, and the latter represents the vividness of the color.
