Fancy Blue
Fancy blue diamonds are among some of the rarest colored diamonds and therefore most valuable. The diamonds range in color from light blue to dark blue. The color breakdown for blue diamonds is as follows: 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.
Other blue diamonds exhibit traces of green or grey. There are a variety of elements that give blue diamonds their distinctive tint. The primary element is boron, followed by hydrogen and nitrogen. Perhaps the most famous fancy blue diamond in the world is the Hope Diamond, which weighs over 45 carats.
Blue diamonds are created when the chemical boron becomes trapped in the diamond’s matrix. Blue diamonds usually contain negligible nitrogen impurities.
