A Bit about Blue Diamonds

Natural Blue diamonds are considered extremely rare and mysterious. They occur in a wide range of colors, from light sky blue to as dark as the Deep Sea.

Most natural blue diamonds are found in the Cullinan mine and the Golconda region.

The second most notable natural blue diamond was purchased in 2008 for $24 million, the Wittelsbach diamond a 35.56 carat deep blue cushion cut.  Both diamonds are rather similar in their color.

How are some diamonds blue?

Natural Blue diamonds owe their color to the presence of boron during their carbon days. So when boron bonds to and becomes absorbed by carbon it caused light to be absorbed in the red, yellow, and green parts of the light spectrum. Causing the color blue to be what you see reflected.

Blue diamonds have been known to contain hints of other colors, modifiers, such as gray, violet, and hues of green. These modifiers are noted on their grading certificates.

The strength of the color is one of the most important factors in the cost of a blue diamond. Along with carat weight, which is true of all diamonds. The value of a blue diamond increases with the intensity and the strength or weakness of the modifying colors visible.

There are several methods that are used to bring out the color that a mined diamond would have become. Unlocking the unique potential of a diamonds color is a permanent process, and unpredictable. Which might just be the coolest part of color enhanced diamonds.
