Why Are Blue Diamonds Expensive?

We have always thought of diamonds to be white and sparking. However, the diamonds are available in many colors, such as black, pink, red, yellow, and blue. In nature, the color appears in a blue diamond because of the trace of a special element titled boron. Hydrogen is also known to cause grayish-blue color in diamonds, while nitrogen causes the yellow color in diamonds. In their turn, greenish-blue diamonds have been found to contain nitrogen impurities and are therefore said to be responsible for the color of the diamond. 

As a rule, it is said that pink diamonds are the most expensive as they are extremely rare, but what about the Blue Diamond Price? In a recent report of the FCRF (Fancy Color Research Foundation), it turned out that blue diamonds are reaching a peak in diamond prices, which is surprisingly high. But why are blue diamonds so expensive? Well, they are very rare to be found in nature, especially the ones very intense in color. 

Blue diamonds are also said to be rare and, therefore, quite expensive – though not as much as pink diamonds. In fact, blue diamonds are so rare that only a few jewelers had an opportunity to see one. A natural blue diamond is expensive and very rare. Thus, some new methods were used to create intensely colored diamonds like fancy blue ones. However, the percentage of successful creation is very small; therefore, the price of a blue diamond is still high.

Using Blue Diamond In Jewelry

As blue diamonds are rare and expensive, blue-diamond jewelry is considered precious. For example, blue emerald-cut engagement rings or rings with round blue diamonds are very expensive and rare to find. The blue diamond is so expensive that one will have to shell out a 5-digit price for a blue diamond that weighs .25 carats only. Therefore, this stone is not used in ordinary jewelry and is a much-preferred option for antique pieces, especially antique engagement rings.

Blue diamonds are not only used in rings but also earrings and necklaces. People frequently request these jewelry pieces with blue diamonds. The problem is to find two similar-sized blue diamonds for the earrings. The only real solution is to find an expert source that can search in the international diamond inventory with the right connections. Because walking past each jewelry store in search of a couple of blue diamonds that have the right size and intensity for your blue diamond earrings will bring no results. And what if your task is not only to find the right stone but also to take the best blue diamond's price in the market?

Blue Diamond Items that rocked the auctions

As diamonds with the color blue are extremely rare, the auction houses from time to time present these items. Weeks before they get auctioned off, those blue-colored diamonds dominate the news. This story happened to the Oppenheimer Blue, Blue Moon of Josephine, and Cullinan Dream. These blue diamonds got sold for a very high, having impressive carat number and intense color. These two characteristics commonly push up the blue diamond price.

For instance, The Cullinan Dream, with 24.18 carats and fancy intense color, cost its buyer $25.3 million USD. In its turn, the Oppenheimer Blue became the most expensive jewel ever auctioned. This 14.62-carat fancy intense-colored blue diamond set a world auction record, fetching the historic high blue diamond price of $57.5 million USD (including the commission and auction fees). The rectangular-shaped blue diamond came in a flanked ring with trapeze colorless diamonds on both sides, creating an even bluer color for the center stone.

This diamond ring style was not always how the Oppenheimer Blue looked, though. The original design featured a verdure eight blades mounting that late Sir Philip Oppenheimer (the reason it's called Oppenheimer Blue) designed for his wife. Yet, it had a more antique/vintage style, so it got a redesign to become more suitable for this century.

Another blue diamond that fetched millions was a 10.10-carat fancy intense blue diamond called De Beers Millennium. Its blue diamond price was $32 million. Generally, among the top 10 auction winners, you can spot some blue diamonds and pink diamonds on the list. See for yourself here.

How Diamond Cut can influence the blue diamond color

Not only the size but also the shape can influence the color appearance of a diamond. A deeper pavilion can make the color more intense because it allows the light to travel further. In addition, fancy-cut diamond shapes can intensify the color. Therefore, blue diamonds are often cut as pear, trillion, heart, or oval.

The more evenly distributed the blue hue, the higher the blue diamond price per carat. When a blue diamond is found, the corresponding shape that saves the largest possible is the first thing to consider.
