The Guide to Colored Diamonds The 4Cs of diamond grading are Color, Cut, Clarity and Carat. The first of those, Color, is based on how clear or “white” the diamond is, with no color at all actually being the most desirable color. However, there comes a point where diamonds which contain color become desirable. Partly because of the unusual effects they can display, and partly because some colors are extremely rare. It can be easy to forget that not all diamonds are created equal. As well as white diamonds, other colors include yellow, orange, red, blue, green, pink/purple, brown, grey and black, with the varying degree of color determining how valuable each stone might be. A white stone with a hint of yellow will be considered much less valuable than a pure white diamond, all other things considered, but a “fancy” yellow stone is considered very desirable past a certain point, and this is true for all the colored diamonds. The specific way in which diamonds are created, with extremes of both pressure and heat being applied to carbon materials means impurities often find their way into the lattice of the minerals, and it is these impurities which largely account for the varying colors that we see.
