Diamonds are known for their classic sparkle and brilliance, but they also come in a variety of colors, including every color of the rainbow. These colored diamonds, also known as fancy diamonds, are rare and highly sought after, making them a unique alternative to traditional white diamonds.

What Colors Do Diamonds Come In?

Diamonds can be found in a range of colors, from the more common shades to the incredibly rare. Here are the main colors:

• White/Clear: The most traditional and widely recognized diamond color.
• Yellow: Caused by nitrogen impurities, yellow diamonds range from pale to vivid.
• Blue: Boron impurities lead to blue diamonds, with the Hope Diamond being a famous example.
• Pink: The exact cause of pink diamonds is unknown, making them extremely rare.
• Green: Radiation exposure can turn diamonds green, though the color is often just on the surface.
• Orange: These diamonds are caused by nitrogen and are quite rare.
• Red: The rarest of all, red diamonds owe their color to a unique crystal structure.
• Purple: Similar to pink, the exact cause is unclear, but these are also rare.
• Brown: Often referred to as "champagne" or "cognac," these diamonds are more affordable.

How Are Colored Diamonds Formed?

Colored diamonds acquire their hues due to various impurities and structural anomalies within the carbon lattice. Here’s how some of these colors occur:

• Nitrogen: This element can cause yellow and orange hues.
• Boron: Results in blue diamonds.
• Radiation: Natural radiation can alter the diamond’s surface, leading to green diamonds.
• Deformation: Structural anomalies during formation can result in pink, red, and purple diamonds.

Why Are Some Diamond Colors More Expensive?

The rarity of a diamond color significantly impacts its price. For instance, red diamonds are the rarest and thus the most expensive. The price of a colored diamond is also influenced by the intensity and purity of its color. The Gemological Institute of America (GIA) grades these diamonds based on color intensity, ranging from faint to fancy vivid.

Investing in colored diamonds can be lucrative due to their rarity and increasing demand. Here are some tips:

• Research: Understand the market and historical price trends.

• Cut: A well-cut diamond will enhance its color and brilliance.
• Certification: Verify authenticity and quality with a GIA certificate.
