Diamonds can be of many colors, but most people associate them with white color. Though, white is not really a white, it’s colorless: the purity comes from shades of red, green and blue combined. This is also the reason why flawless white diamonds are very rare. But certain colored diamonds are not less rare and valuable.

Diamonds are usually graded by the 4Cs, but more factors come in play when a colored diamond is being evaluated. To learn his beauty it needs to measure the light performance. Color occurs due to the long formation process deep under the ground. The certain level of color saturation in a particular diamond is a result of geological and chemical factors. The stronger the pressure, the richer is the color.

Colored diamonds may be of many shades. The lesser valuable are the most common — the browns and yellows. For the long time brown diamonds were considered not gem quality and were sold to building or space exploration companies. Still today they share the market with all the other shades, as they had been rebranded and presented under the “Chocolate diamonds” name.

The blues, greens and pinks are more rare and so they are evaluated higher. But the most valuable and expensive diamonds are red. Best of them can be sold more profitably than the purest colorless diamonds. Cut, carat weight, shape are also the factors to influence the price of colored stones and fuel the trading potential of a stone.

The diamond may be of a low color quality, but being clear and excellently cut it will cost more and may be traded more actively. Still the diamonds with the deepest saturation are the most welcome on diamonds markets. On Diamond Open Market we grade the level of hue and intensity as it’s accepted by GIA’s guide to fancy color diamonds:

Faint

Very Light

Light

Fancy Light

Fancy

Fancy Intense

Fancy Dark

Fancy Deep

Fancy Vivid

Of course, classic white diamonds have higher trading volumes than colored diamonds. But we can’t compare the sizes of these markets. Colored diamonds share is demonstrating persistent increase not only in volume, but also in price. For the last ten years it have raised in price for overwhelming 70%. The most impressive growth shown the fancy blues, which rose almost 9% just for one quarter of 2018.
