Wala Gems shares its knowledge and expertise about factors that affects its valuation. A diamond quality and value is judged on four fundamental characteristics known as 4 C's .These are Carat weight, Clarity, Color and Cut. The creation of the Diamond 4Cs meant two very important things: diamond quality could be communicated in a universal language, and diamond customers could now know exactly what they were about to purchase.
A diamond's color grade actually refers to the absence of color. In other words, diamonds that are white, containing little or no color, receive higher quality grades than those with noticeable color.
A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. A D-to-Z diamond color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to master stones, stones of established color value.
