Updated / February 14, 2017
In a recent report of the FCRF (Fancy Color Research Foundation) it turned out that blue diamonds are reaching the peak in diamond prices, which is quite high - but why are blue diamonds expensive? Well, these diamonds are very rare to be found in nature, especially the ones very intense in color. We have always thought of diamonds to be white and sparking. However, the fact is that diamonds are available in colors such as black, pink, red, yellow and blue. As a rule, it is said that pink diamonds are the most expensive as they are extremely rare but what about Blue Diamond Price? Well, Blue diamonds are also said to be rare and therefore are quite expensive – though not as much as the pink diamond. Blue diamonds are so rare that only a few jewelers would have had the opportunity to see one. There have been new methods used wherein intensely colored diamonds such as fancy blue have been created. However, the percentage of successful creation of blue diamond is very less and therefore the price of blue diamond is still high.

Creating an even bluer color for the center stone. This diamond ring style was not always how the Oppenheimer Blue looked. The original design was a verdure eight blades mounting that late Sir Philip Oppenheimer (reason why its called Oppenheimer Blue) designed for his wife. Yet, this design was a more antique/vintage style so it got an redesign to make it more suitable for this century.

How Diamond Cut can influence the blue diamond color
Not only the size can influence the color appearance of a diamond, shape does too. A larger diamond or deeper pavilion can make the color more intense because the light can travel further. In addition, fancy cut diamonds can help the color intensity. Blue diamonds are therefore often cut in fancy shapes such as pear, trillion, heart or oval.
The evenly distributed the blue hue the higher the blue diamond price per carat. That is why when a blue diamond is found, a lot of thought goes into what shape is best while keeping in mind that the larger the size is the better.
