Whilst many people believe that the most valuable diamonds are absolutely colorless, and they are certainly expensive and sought after because colorless diamonds are exceedingly rare, other people prefer colored diamonds. Colored diamonds are called “fancies,” and can be far more expensive than white diamonds of similar cut and carat weight.

Diamonds become colored because of the impurities within them, but no matter what color they are, diamonds are made almost entirely of pure carbon.

All diamonds were formed millions of years ago when carbon was transformed by the immense heat and pressure under the earth.

Know your Pink Diamond

Diamond sellers have slightly different criteria for what constitutes a quality pink or colored diamond than they do for a colorless or white diamond. They believe that if a diamond is colored it should be judged on the intensity, richness and brilliance of its color. These diamonds are graded from ‘faint’, where there is barely a shade of color, to ‘vivid’ where the color is rich and startling.

Pink diamonds are also categorized according to their secondary color, for example purplish pink, orangy and brown pink.

Carat, or the weight of the diamond, is especially important for fancy diamonds. The larger the carat, the more expensive a fancy diamond will probably be, unless it has obvious and insurmountable flaws.

Clarity relates to the diamond’s flaws, and because it is colored the flaws in a pink diamond don’t matter as much as a colorless diamonds. The flaws, which also called inclusions, are often hidden by the diamond’s color. Another important criterion when buying a pink diamond is its shape. This is the shape that it has when it is looked at from the top.
