HOW TO CHOOSE

Even with a deep color, fancy yellow diamonds showing a strong brownish tint will lack beauty, making them ill-suited for jewelry. Light and beautiful yellows can sometimes be had at relatively low prices. It is essential that the color be distinct when the stone is viewed face-up. A fancy-color grading report should be thought of as proof of natural color, but it is important not to depend on the color terms: View stones with your own eyes, and select the one that satisfies you.

The value of a one-carat-size fancy yellow diamond of jewelry quality is approximately US $9,000 for the stone alone. (2001)
