Up until the middle of the twentieth century, there was no agreed-upon standard within the jewelry industry to judge diamonds. Around that time, the Gemological Institute of America (GIA) created the first, and now globally accepted, standards for classifying diamonds. The standards created by GIA include classifications for Cut, Color, Clarity and Carat Weight.

Today, the 4C’s have become a universal method for assessing and assigning individual diamond characteristics for any diamond in the world. The use of the 4C’s for diamonds means diamond quality can be communicated in a universal language that both industry tradespeople and consumers alike can understand.

The term “Color” as it applies to assessing a diamond with the 4C’s actual refers to the lack of color. When conducting an evaluation of a diamond for color, the highest or “best” color diamonds are those who have an absence of color. A diamond that Is chemically pure and structurally perfect will have no hue, and therefore, a higher value. The Gemological Institute of America’s diamond color-grading scale ranges from D-to-Z and measures the degree of colorlessness by comparing diamonds under controlled lighting and precise viewing conditions to a known set of “master” diamonds used exclusively for evaluation, and whose color value has been previously established. When it comes to distinguishing color with the naked eye, the variations are often so hard to detect that they are impossible for an untrained eye to see. especially on the higher end of the color scale, which are diamonds in the D, E, F color category.

Your diamond color choice, and turn it into the ring of your dreams! The prices that correlate with these distinctions, even though in many cases they are difficult to see, can make a huge difference in the final cost. As you progress down the color scale towards Z, the diamond color becomes “warmer,” and show more body color that is easier to see with the naked eye. If you are looking to purchase a diamond over a carat, and you don’t like the look of a “warmer” diamond, then color may factor higher into your consideration. As the carat weight of a diamond increases, the color (or lack of) becomes easier to perceive with the naked eye.
