Color refers to the relative tint that the diamond material may possess.
When most diamonds form their coloring ranges from tints of yellow to brown.
A diamond's color is graded on a scale beginning with D, (absolutely colorless) and continuing through the alphabet to Z, (strongly tinted).
What most people don't understand about diamond color grading, is that this grading must be done prior to mounting the diamond, by viewing the stone in a face down position through the bottom. When the diamond is viewed from the top, (face up), there are many grades of color that are indistinguishable from each other.
For more information on Color, take a look at our videos on the 4Cs.
When you visit one of our Kessler locations we will show you how difficult it is to determine color in a really well cut diamond, a fact that never fails to amaze our clients.
