The Four C’s that are unique to each diamond determines the quality and value of a finished diamond.
Color is the second most important characteristics of a diamond after cut. Diamonds come in different colors, but the most common color is subtle shades of yellow and brown. The translucent diamonds are considered to be structurally perfect, but they are rare to come by. Diamonds get their color by the presence of trace elements like nitrogen, which imparts yellow color, boron imparts blue color or sometimes the natural radiation from nearby rocks trap electrons impart green surface color and pink or red shades are due to changes to the electron structure during the voyage to the surface.
Diamonds are valued by how closely they approach colorlessness - the less the color, the higher their value. A color grade of D is the highest grade possible, while Z is the lowest on the scale.
