Diamonds are renowned for their brilliance and clarity, but many people are surprised to learn that they can come in a variety of colors. These colored diamonds are not only beautiful but also rare, making them highly sought after by collectors and jewelry enthusiasts.

What Colors Can Diamonds Be?

Diamonds can be found in nearly every color of the rainbow. The most common colors include:

• Yellow
• Brown
• Blue
• Green
• Pink
• Red

Each color is the result of specific impurities or structural anomalies within the diamond. For example, yellow diamonds get their color from nitrogen, while blue diamonds contain traces of boron.

How Are Colored Diamonds Formed?

The formation of colored diamonds is a complex natural process. Here are some key factors:

• Impurities: Elements like nitrogen, boron, or hydrogen can alter the diamond’s color.

1. Hue: The primary color of the diamond.
2. Tone: The lightness or darkness of the color.
3. Saturation: The intensity of the color.

The GIA color scale for colored diamonds ranges from "Faint" to "Fancy Vivid," with the latter being the most desirable and valuable.
