Diamond Education

Second to cut, a diamond’s color is the second most important factor to consider, as it can be noticeable to the naked eye.A chemically pure and structurally perfect diamond has no hue, like a drop of pure water, and consequently, a higher value. While many diamonds appear to be colorless most contain tints of yellow, brown or grey tint in varying degrees. GIA’s D-to-Z color-grading system measures the degree of colorlessness by comparing a stone under controlled lighting and precise viewing conditions to masterstones of established color value.The scale begins with the letter D, representing colorless, and continues, with increasing presence of color, to the letter Z. Many of these color distinctions are so subtle that they are invisible to the untrained eye; however, these distinctions make a very big difference in diamond quality and price.
