Why Should You Invest in Blue Fancy Color Diamonds

By Ryan on Jan 21, 2022

Blue diamonds are one of the rarest and most valuable types of jewelry. They are just as unusual as red and pink diamonds. The element boron is the main cause of a diamond’s blue color.

Blue diamonds are exquisitely beautiful, and rich in lore. They are highly valued by diamond enthusiasts and jewelry experts because of their unusual combination.

Are Blue Diamonds Real?

Naturally they are found beneath the earth’s surface with their natural blue hue, and they are not treated or enhanced to acquire color, but during the prep process, the cutting and polishing may affect the color. Blue diamonds range in color from light blue to deep blue often with a secondary hue like violet, gray, or green.


Blue Diamond’s Intensity Levels

The strength of a diamond’s color is referred to as the color intensity level. Each Fancy diamond has different intensity levels by which it’s evaluated.

Given the significance of the color, blue diamonds are graded along three different metrics i.e., hue (the actual color), tone (the lightness or darkness of the color) and saturation (how strong or weak the color is). According to GIA’s system, it is graded as below:

For blue diamonds, the grading scale includes Faint Blue, Very Light Blue, Light Blue, Fancy Light Blue, Fancy Blue, Fancy Intense Blue, Fancy Deep Blue and Fancy Vivid Blue. Fancy Dark is also a possibility if a secondary color is present.

They are typically fashioned with yellow gold, silver or platinum settings and can be found in combination jewelry pieces like pendants, earrings rings bracelets necklaces.

Blue Diamonds History

Blue diamonds were first discovered during the 18th century when a very large blue diamond was unearthed in India. The stone eventually made its way to Amsterdam where it was bought by a French merchant who named it “The Blue Diamond of the Crown” and eventually sold to King Louis XVI.

The diamond was used for many royal jewelry pieces, including one that is said to be part of Marie Antoinette’s wedding jewelry set which can now be viewed in both New York City and Versailles museums.

Only a few mines in the world produce blue diamonds: the Cullinan mine in South Africa, the Argyle Mine in Australia, and the Golconda colliery in India.

Today, blue diamonds can be found in jewelry stores all over the world. They are often quite expensive and can range in price from a few thousand dollars to well over one million dollars.

The most famous blue diamond in the world is known as the Hope Diamond. Weighing in at 45.52 carats, it is said to be cursed and has been the source of much misery for its owners. It is currently on display at the Smithsonian Museum in Washington D.C.

While blue diamonds can be naturally found in nature, they can also be produced in a lab. Of course, lab grown versions are less valuable than their natural counterpart. The main difference between these two types of is the color.

First of all, lab grown blue diamonds are actually white diamonds that have been treated with heat. Therefore, they are not truly blue diamonds at all.

Second, they tend to have a noticeably different tone than blue diamonds found in nature. This difference in hue is easy to notice by a gemstone professional.

One of the most desired natural blue diamonds is the famous Hope Diamond, weighing 45.52 carats. It is shrouded in legend and lore. The Hope Diamond was stolen from the French Crown Jewels in 1762 during the French Revolution. The Hope Diamond is housed at the Smithsonian Natural History Museum in Washington, DC.

Blue Diamonds Meaning 


Blue diamond is associated with the idea of good health, peace, serenity, and love in life. It shields unnecessary egos, fights, and misunderstandings in a relationship. It also symbolizes trust, loyalty and wisdom. It is believed that wearing an engagement ring with blue diamond proves to the bride how valued the relationship is.


Blue Diamond price

The carat weight and intensity of blue color dictate how much a blue diamond is worth. Because of blue diamonds’ rarity, they’re usually more expensive than white diamonds and other fancy color diamonds.

Blue diamonds are more valuable than most colored diamonds, but just like all other diamonds, their prices are determined based on the diamond’s color, color intensity, size, and clarity with an emphasis on the intensity of the color. Blue diamonds are highly sought after by diamond collectors and enthusiasts worldwide.

A very small blue diamond can cost a few thousand dollars, and a large one such as the Wittelsbach-Graff diamond can cost millions. Because they are so rare, most blue diamonds tend to get snatched up very quickly and fetch very steep prices. Nevertheless, no diamond collection is complete without a natural blue diamond.

The price of a 0.3 carat light blue diamond costs $15,700 on average. The price of a 0.5 carat light blue diamond is $26,280 on average. Deep blue and vivid blue diamonds cost much more—around $75,000 for a 0.25 carat diamond. As you increase in color intensity and carat weight, blue diamond prices extend beyond $100,000, $200,000, and more. The value of a blue diamond rises significantly with increased hue intensity.

Smaller blue diamonds, like those below 0.3 Carat, are more affordable and can be used to make a special jewelry piece if paired with other stones.

Figuring out how much a natural blue diamond is worth is challenging because the prices range dramatically based on color and secondary hue. Because blue diamonds are considered rare and unique in their specific color, it’s virtually impossible to determine a blue diamond price per carat. That is why determining if a blue diamond is a good value is critical.



Blue Diamonds vs Blue Sapphires

Blue diamond’s grading scale varies from faint blue, very light blue, light blue, fancy light blue, fancy blue, fancy intense blue, fancy deep blue and fancy vivid blue (as seen in the image above) and derive their color from boron impurities. As the content of boron increases, so does the intensity of the blue color.

Sapphires can also display a variety of shades, from a pale sky blue to a rich, royal blue. The deeper the hue of a sapphire is saturated, the higher its titanium content. Blue is the most popular and traditional hue for sapphire, although Sapphires may be found in a variety of hues.

The best way to know for sure whether you are looking at a blue diamond or a blue sapphire is to have a certified gemologist or gem lab examine it for you.

Why is buying blue diamond a more interesting investment?

Many investors find their way to colored diamonds more and more often. In general, colored diamonds are more expensive than colorless diamonds, prompting some investors to move on to other gemstones.

There are strict laws regarding the purchase and sale of diamonds as an investment throughout the world. If you buy a diamond as an investment, you will always receive a certificate at BNT Diamonds from specialized laboratories GIA, IGI or HRD for the protection of both the investor, the trader, and the jeweler.

In addition, diamond knows a stable, gradual price increase. The fact that this is a long-term trend is evidenced by the fact that there are no indications it will change.

Blue diamonds may be a lucrative investment if you have thought it through carefully. These vibrant gems, like their colorless counterparts, offer significant commercial appeal. They are a niche market, however, and are frequently handled by specialist auction houses. To get the most out of investing in blue diamonds, contact a professional, such as BNT Diamonds’ specialists.

Investing in blue diamonds can be profitable in the long term, due to their scarcity. The scarcity of these diamonds has only increased over the years, which led to a significant increase in demand but with limited supply.



If you’re looking to add a touch of luxury to your jewelry collection, consider purchasing a blue diamond. They are sure to impress friends and family members and will last a lifetime if properly cared for. It is a smart investment piece that will increase in value as the years go by.
