Diamonds are not only available in the classic clear or white hue. They can naturally occur in a variety of colors, including yellow, blue, pink, and green, among others. These colored diamonds, also known as "fancy diamonds," offer a unique and vibrant alternative to traditional white diamonds.
What Causes Diamonds to Be Different Colors?
The color of a diamond is determined by the presence of trace elements or structural irregularities during its formation. Here are some examples:
-
Yellow Diamonds: The presence of nitrogen atoms can cause a diamond to appear yellow. The more nitrogen, the deeper the yellow hue.
-
Blue Diamonds: Boron impurities give diamonds a blue color. The Hope Diamond is a famous example of a blue diamond.
-
Pink Diamonds: The exact cause of pink diamonds is not fully understood, but it is believed to be due to changes in the diamond’s crystal lattice.
-
Green Diamonds: Exposure to natural radiation over millions of years can give diamonds a green color.
How Are Fancy Color Diamonds Graded?
Fancy color diamonds are graded differently than traditional white diamonds. The Gemological Institute of America (GIA) grades them based on the hue, tone, and saturation of their color.
-
Hue: The basic color of the diamond (e.g., blue, pink, yellow).
-
Tone: The lightness or darkness of the color.
-
Saturation: The intensity or purity of the color.

While diamonds can come in virtually any color, some hues are more sought after than others.
Yellow Diamonds
Yellow diamonds, often referred to as "canary diamonds," are among the most common and affordable fancy colors. Their sunny hue is popular for its warmth and vibrancy.
Blue Diamonds
Blue diamonds are extremely rare and valuable. The presence of boron gives them their unique color. The Hope Diamond, one of the most famous blue diamonds, exemplifies their allure.
