Blue Diamonds
One of the more frequently seen colored fancy diamonds is the blue diamond. By no means does that mean they are readily available in jewelry stores, even tho they are more common than the red, green, or purple diamond, blue diamonds are still extremely rare and expensive.
The occurance of color in diamonds is mostly created by inclusions or a slight trace of other elements beside carbon. Most blue diamonds are of a pale blue color, some are slightly more vibrant. The color grading for blue diamonds depends much on your personal taste and the shade of blue. An extremely rare shade, such as green blue, will result in much higher prices.
