About the diamond’s color

Color diamonds are judged somewhat differently than colorless diamonds, and for good reason. They are in a category all their own. As a natural diamond rarity, it’s easy to see that each stone has a color all its own, even within its color niche.

All diamonds are evaluated by four key attributes of diamond quality, called the 4Cs. These are Color, Cut, Clarity, and Carat Weight. However, unlike white (colorless) diamonds where the 4Cs are of equal importance, the color exhibited in a Fancy Color Diamond is the most significant attribute of all.

What Causes the Color

The unique colors in these stones are caused by different trace minerals within the crystal structure of the diamonds. Depending on the origin of the stones, meaning where they were sourced, certain minerals are more likely to be present. This increases the odds of these areas producing specific colors for which the areas are known.

Unlike yellow diamonds whose color is attributed to trace amounts of nitrogen, blue diamond color is the direct result of the addition of boron in the crystal structure. Purple or violet diamond colors are partly caused by the presence of hydrogen, and mostly from its crystal distortion. Green diamonds, a rarity within this group, owe their color to exposure to atomic radiation or radioactivity. Some diamond coloration remains a mystery, like the cause of color in pink diamonds. It is believed that lattice distortion in the crystals allows the eye to see pink shades. Scientific evidence suggests that pink diamonds owe their color to high pressure graining, resulting in a compressed internal structure. Within the industry, this is referred to as ‘plastic deformation,’ which always occurs during the crystal growth phase.

Pink Diamond Color Scale

Similar to other colors, pure pink diamonds without any secondary hues are rarer and more valuable. However, because of its dramatic lush appearance, a purplish pink diamond is also considered highly desirable among collectors. Many pink diamonds in today’s market contain some of the following secondary or modifying colors: Purple, Purplish, Brown, Brownish, Grayish, Orangy, Brownish Orangy, and Brownish Purple.

Color intensities

Pink colored diamonds can be found in every intensity grade as recognized by the GIA grading scale; Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark intensity grades depending on the color combinations within the stone.

Pink diamond’s mining areas

While pink diamonds have been found in deposits around the world, their occurrence has remained exceedingly rare, making each discovery news-worthy around the globe.

The most important modern day source for pink and red diamonds remains the legendary Argyle mine in New South Wales, Western Australia. It operated for nearly 40 years producing a disproportionately large portion of pink diamonds from its annual yield. When it closed in 2020, it signaled an end to a remarkable era, with no similar mine producing such a quantity of pink stones.

Polishing process

Polishing pink diamonds is a delicate process requiring skill and extraordinary precision in planning. The polisher must first study the rough to determine where blemishes and cracks may be present inside the crystal. The idea is to work around any flaws so the best possible clarity will result in the diamond. But that has to be balanced with saving as much weight as possible so the end result will be the largest carat size that can be achieved.
