Its all about color

Natural color diamonds are true miracles of nature, formed deep within the Earth millions of years ago. Now, having found their way to the surface, they are visible for all of us to see. These gems are rare and renowned for their beauty, encompassing a wonderful palate of color including pinks, champagnes, cognacs, yellows, greens and blues, oranges and even reds.

Strength of color

The strength of color is one of the most important factors in determining the value of a natural color diamond. The value of a natural color diamond increases with the intensity of the most prominent color within the diamond. In an attempt to bring some uniformity to the industry description of Natural Color Diamonds, gem analysis laboratories have developed the fancy color diamond color scale to classify the strength or intensity of a diamond’s color.colored diamond logo
