Eccentric Origins

The origin of blue color can be traced to the presence of traces of boron in the crystalline structure of the diamond. Formation of a blue diamond is an extremely rare event in our planet’s history. In general, diamonds are formed under very specific conditions in very limited zones of the earth’s mantle.

To make matters more difficult (if not impossible) blue diamond formation requires a still more specific and special environment. Boron needs to replace nitrogen in this scenario. When a blue diamond is forming, boron particles are entrapped inside its crystal lattice. Boron absorbs yellow from the visible spectrum and reflects the blue, thus imparting blue color to the diamond. The unusual chemical make-up adds to the fascination for these diamonds.

Color diamonds are extremely rare. One stone among the tens of thousands mined will exhibit any color. And blue diamonds are among the rarest of rare. They are rarer than yellows, reds and pinks. However, they are less rare than reds, violets and purples.

In ancient times, the Golconda region in India was a well known source of blue diamonds. The Hope Diamond is known to have been born here. Today, the Cullinan Mine in South-Africa is a small but consistent source of blue diamonds.

Importance Of Color Strength

In colorless diamonds (erroneously known as white diamonds) value depends on absence of color. More colorless is a diamond, higher is its value. On the other hand, value of fancy color diamonds depends on presence of colors. Saturated colors are more valuable. The system for color-grading fancy color diamonds is designed to accommodate the fact that not all colored diamonds have the same depth of color.

Color diamonds are graded according to color saturation. The grades range from fancy, intense, vivid and deep to dark. Fancy denotes the lightest and deep denotes the darkest. Vivid denotes the most desirable color saturation.

Stronger and richer colors are extremely rare and highly valued. Accordingly, the price differences can be extreme too.

Among fancy color diamonds yellows and browns happen to be relatively common colors. Diamonds with noticeable tinge of any other hue are significantly rarer. Even with weak saturation or light tones they are eligible to be called as fancy color diamonds so long as they show color in the face up position. Red, Green & blue diamonds with medium to dark tones & modest saturations are exceptionally rare.

Diamonds displaying blue color in the face up position occur in a range of shades ranging from faint to intense, vivid, deep & dark. Accordingly, blue diamonds are graded as Faint Blue, Very Light Blue, Light Blue, Fancy Light Blue, Fancy Blue, Fancy Intense Blue, Fancy Dark Blue, Fancy Deep Blue, and Fancy Vivid Blue. A fancy intense blue diamond displays more color than a fancy blue diamond. But vivid blue is the pinnacle of color not easily found. It drives the price to stratospheric levels.

All fancy color diamonds usually display secondary hues. Common secondary colors in blue diamonds are greenish and greyish hues. These are greenish blue, bluish-gray, steely-gray, & vioiletish-blue-gray. Secondary colors have a downwards influence on value. Pure blue always commands a higher premium.

Size Matters

The size of the stone is another important factor that adds to the price.

Diamond mining in an entire year in the whole world will produce less than 10 rough blue diamonds in the 4 to 7 carats size-range. After polishing these stones turn out to be in the 1 to 3 carats size range. So a large blue diamond is a truly special gem.

Golconda was once renowned for the diamonds found on the south-east at Kollur Mine near Kollur (modern day Guntur district), Paritala (modern day Krishna district) and cut in the city during the Kakatiya reign.

Many famed diamonds are believed to have been excavated from the mines of Golkonda, such as:

• Darya-e Nur

• Nur-Ul-Ain Diamond

• The Koh-i-noor

• The Hope Diamond

• The Regent Diamond

• Wittelsbach Diamond

Since its discovery in the early 1600s, the hope diamond has gone across oceans and continents, and passed through the hands of kings and commoners. It has an infamous past, having been sold, stolen, recovered and re-cut from the French Blue diamond once in possession of the French Royal Treasury.
