The blue diamond sometimes varies in hues. One of the most common hues is the deep aquamarine. Diamonds with this color seem to look better in appearance with more color saturation. There are some that are too pale, known as little aquas. They do not look great on smaller stones, but they boast their beauty in large stones.

There is also the so called green tinge. But unlike the deep aquamarine, the green tinge colored diamond is not that favored, although they tend to be attractive. It is for this reason that green tinge diamond is not so common.

Aside from deep aquamarine and green tinge, the Gemological Institute of America has made eight distinct color saturation grades for the blue diamond. These colors include very light, light, fancy light, fancy, intense, deep, dark, and vivid. Certain color combinations, however, was discovered, such as the gray blue and the green blue. Well, according to some studies, these colors found in blue diamonds can be accounted to the stones boron content. It is actually the mineral, boron, which makes such color variations possible.

Just like the colorless and the rest of the colored gemstones, the blue diamond is produced in different cuts and shapes.The most well known is the round brilliant, which is but considered as the modern form. There is also the heart or romantic shape, which is designed as a modification of the round brilliant cut. For those who are romantics, this kind of cut and shape will surely suit your needs. In addition, this diamond sometimes comes in pear shape. This shape is to some degree similar to the heart shape in that it is also a modification of the round brilliant.

Today, certain modern shapes were developed for blue diamonds. Of the available, the princess cut is the most well known. It attracts thousands of customers worldwide mainly for its unique combination of square with the brilliance of a brilliant cut. Aside from princess, there is also the so called Marquise or Navette cut, which has long been deemed as better in fancy colored diamonds than in plain vanilla. Just like the basic shapes, the marquise cut is an adaptation of the round brilliant.

The blue diamond further varies in carat weight and the degree of clarity. The carat weigh, however, do not necessary denotes the quality of it. It just defines the diamond by its weight. But clarity, on the other hand, counts much. Just like the cut and color, it affects the quality and price of the blue diamond. As what many have said, the clearer the diamond is, the better it sparks and the higher it costs.

Most of these diamonds today are sold more expensive than the near colorless ones. They are often treated to obtain the desired color, and that several treatments for this gemstone have been formulated and sold for the jewelers to use.
