Why Learn About Colored Diamonds?

Colored diamonds are rare in nature.

Among the total diamond rough produced, only less than 2% naturally exhibit intense body color, which are the rough stones of colored diamonds. Furthermore, only one in ten thousand finished diamonds can reach the "colored diamond grade."

The colored diamond market is gradually expanding in the consumer market.

Over the past 20 years, the colored diamond market has expanded from traditional avenues such as auction houses to the jewelry market. Driven by numerous high-price auction news, public figures, mainstream media reports, and increasing consumer demand for colored diamonds, the market has continued to upgrade.

The price of colored diamonds has been rising, with a promising future.

Colored diamond prices have increased year by year, with some even doubling in value within 5 to 6 years. Unique and rare colored diamonds can fetch prices exceeding US$1 million per carat.

The value of colored diamonds is determined by parameters such as color and size.

As decorative and investment jewelry, the identification, evaluation, and grading system of colored diamonds is increasingly demanded by many. Even subtle color variations can significantly affect the price of the gemstone. Improving one's ability to independently judge diamond quality requires professionalism and authority to gain trust.
