Primary Diamond Colors

There are color diamonds in every color of the rainbow, but some are easier to get than others. These include pink, red, violet, yellow, green, blue, purple, orange, brown, gray, and black. Usually when a color diamond exhibits just the primary color and has no secondary color, it will be more valuable and it’s price will be higher. However, the diamond’s value also depends on other features such as color intensity, size, and cut.

Secondary Diamond Color Combinations

Since color diamonds are so rare, often a color diamond will be comprised from several colors. The main color will be supplemented by one, two, or even three additional hues.

These color combination diamonds are still very rare yet their value will be less than pure color diamonds.
