How to know about the Diamond Color





As we select a diamond, the diamond color is one of the most important factors to consider. When choosing a diamond, most people notice-whether the diamond is "white" or not. It is also one of the most significant factors affecting value.

Today, the color designation frequently used to grade an absolutely clear, colorless diamond is the letter D. The progresses of GIA classification are from D, the finest classification on this scale (colorless), through the alphabet Z, getting progressively yellowish.

D: Absolutely colorless. The clearest diamond color grade, it is very rarely.
E: Extremely colorless. Trained gemologists can detect slight color. A high-quality diamond.
F: Colorless. Only trained gemologists can detect color. Lowest of the colorless grades.
G-H: Near-colorless. When compared to better color grades, slight color detectable, but is a much better value.
I-J: Near-colorless. Color slightly detectable. An excellent value.

The most rare and valuable is the colorless grade D, white colors of grades M to Z are recognizable with the light yellow grade Z being the lowest of all.

The color of a diamond plays a crucial role in determining its worth. ‘Colorless’ diamonds are extremely rare and valuable, the most common are ‘near colorless’ and ‘light yellow’. The rarity and worth of a diamond directly relate to its intensity of whiteness. Similarly rare are ‘colored diamonds’ that are even more precious than their colorless relatives.
