Blue Diamonds

Blue Diamonds have long been associated with kings and royalty, and have a vast history of importance as historical diamonds. They can contain one or a combination of shades of gray, green, and violet.

Blue diamonds derive their color largely from the presence of boron during the formation process. The more boron atoms, the more intense the color is. In addition, there are greenish-blue diamonds, where the color could be a result of the presence of radiation in the earth at the time. In exceptional cases, a grayish-blue color has been discovered to be caused by the presence of hydrogen.

Frequently, they have little streaks of gray, giving them a steel blue color, and some have traces of violet.
The blue color changes with light much more than do other colors. Blue diamonds do not have the blue color of sapphires, but either a sky blue or a darker metallic blue.

As well as the pure blue color, theycan contain one or more of the following overtone colors; Gray, Grayish, Green, Greenish, Violetish, Gray Greenish, and Graysih Greenish.

Blue diamonds are found in all intensities: Faint, Very Light, Light, Fancy Light, Fancy, Fancy Intense, Fancy Vivid, Fancy Deep and Fancy Dark. The itensity grades depend on the color combinations found in the stone.

RED DIAMONDS

Natural red diamonds are the rarest of all natural color stones. So much so that fewer than 10 such diamonds are produced annually in the whole world.
