The Diamond Color Scale
To determine which color is right for you, it’s important to learn about the diamond color scale so you know how diamonds are graded.
Grades D, E, and F are considered colorless, which means there is no color visible to the naked eye or when the stone is under magnification. The D grade is the highest that a diamond can receive on the color scale, but only a trained professional would be able to spot the difference between a D, E, and F diamond.
D color 1.38 carat Loose Emerald Diamond
Grades G, H, I, and J are considered nearly colorless, which means they barely have any color at all. Any color that is found in these stones is not very noticeable to the naked eye. Diamonds that fall under this category are much more common than colorless diamonds, so they aren’t nearly as expensive.
H color 2.20 carat Loose Emerald Diamond
J color 1.50 carat Loose Emerald Diamond
Grades K, L, and M are given to diamonds with a faint tint of color. The warm, slightly yellow tint is noticeable to the naked eye. Some people prefer this due to the price advantage.
M color 0.96 ct Loose Emerald Diamond
Very Light Tint/Light Tint
Diamonds that have been given a grade of N-Z have very noticeable yellow or brown coloring.
