Since its founding in 1984, Casa D’Oro has prided itself on offering not just the highest quality diamonds, but also expert guidance and personalized service. When it comes to understanding the various aspects of diamonds, color plays a significant role, and it can greatly impact the value of these precious gems. In this article, we delve into the intriguing world of colored diamonds, shedding light on which color holds the highest market value.

Basics of Diamond Coloration

Diamonds get their colors from trace elements and defects in their crystal lattice structure. Ranging from colorless to vibrant hues of yellow, blue, brown, and even green or red, each diamond has a unique appeal.

The Color Grading System

Our trained experts at Casa D’Oro follow the globally recognized diamond color grading system. This method grades diamonds from D (colorless) to Z (light yellow or brown). However, colored diamonds, often referred to as ‘fancy color diamonds,’ have a separate grading system based on the hue, tone, and saturation of color.

Popular Diamond Colors and Their Market Value

At Casa D’Oro, we offer a wide range of diamonds with varying colors and prices.

  • White (colorless) diamonds: These diamonds are the most common and their value increases with the absence of color.
  • Yellow diamonds: Their prices can vary widely, with fancy intense or fancy vivid yellow diamonds commanding higher prices.
  • Blue and brown diamonds: Generally more affordable, these diamonds offer a unique alternative for those seeking a colored gem.

The Most Expensive Diamond Colors

When it comes to the most expensive diamonds, a few colors stand out:

  • Pink diamonds: Their romantic hue combined with their rarity makes them highly sought after.
  • Blue diamonds: Famous blue diamonds like the Hope Diamond have set high standards for the value of this color.
  • Green diamonds: Natural green diamonds are extremely rare, and their unique color can command a high price.
  • Orange and violet diamonds: Due to their rarity, these colors can also fetch high prices in the market.

The Rarity and Value of Red Diamonds

The pinnacle of rarity and luxury in the world of diamonds is the elusive red diamond. At Casa D’Oro, we consider it a privilege to have witnessed the beauty of these gems. Their value can easily exceed that of any other diamond color, owing to their rarity.

Factors Affecting the Value of Colored Diamonds

Several factors affect the price of colored diamonds:

  • Color intensity: The more intense the color, the higher the value.
  • Diamond size and carat weight: Larger diamonds are rarer, thus more expensive.
  • Clarity and cut quality: Diamonds with fewer inclusions and superior cut quality command higher prices.

Notable Expensive Colored Diamonds in History

Throughout history, some colored diamonds have become world-renowned. The Hope Diamond, with its deep blue color, the Pink Star, and the Moussaieff Red, the largest red diamond in the world, are examples that reflect the immense value of colored diamonds.
