Color of a diamond refers to the saturation of color in the diamond. More color present in the diamond means that some of the colors will be filtered out when the light is reflected back thus lessening the fire in the diamond. Colorless diamonds are rarer to find and more appealing to the eye and as such more valuable.
Each diamond can be put in one of the following color categories:
Most of our diamonds fall between D and J color but if we see a value for our customers in K and L colors we add that to our diamond selection as well.
Some people confuse the fluorescence of a diamond with its color but what needs to be pointed out is that fluorescence is only detectable by a trained gemologist under special lights. Some fluorescence makes the diamond look brighter and whiter while others make the diamond look hazier.
