Blue Diamonds: The Heart of The Ocean

Diamonds are undeniably some of the most gorgeous things ever. While white diamonds and even yellow diamonds are exquisite but common, blue diamonds are extremely rare. 


Coupled with their beauty, intensity, and ability to make heads turn, they are one of the most valuable diamonds in the world. Because of the beauty and intensity of these diamonds, they’re also known as the heart of the ocean.

About Blue Diamonds

Let’s dive into these.

Blue Diamonds only distinction from other diamonds is their blue coloration, which gives them a distinct hue. Amongst all the fancy diamonds that exist, they are the rarest and most sought after.


As a result of this rare color, which contrasts with the more common white diamonds and yellow diamonds, blue diamonds have become increasingly valuable to jewelers, museums, and private collectors.


Due to their usually intense nature, blue diamonds are often thought of as artificial or even-tempered. However, blue diamonds are just the same as others, naturally occurring elements of carbon fused and solidified during times of intense pressure and heat over centuries.

    However, unlike other diamonds, blue diamonds are also composed of the element boron, which gives them their natural blue hue. Nitrogen also plays a significant role in determining the intensity of the hue. For instance, if the concentration of Nitrogen is high during the formation process, the diamond will have a deeper shade of blue. If there isn’t so much Nitrogen, the diamond will have a lighter shade of blue.


    Blue diamonds are quite rare because less than 1% of diamonds that occur and are discovered during mining are naturally blue. Considering that diamonds have become increasingly rare over the years, their value has also skyrocketed. Presently, blue diamonds are more valuable than ever, and as a result, supply cannot match demand. Still, demand is likely to increase as time goes on, while supply will most likely dwindle.

    Today, there are only about two places that miners still come across these diamonds. The only places where you can find blue diamonds are the Cullinan Mine in South Africa and the Argyle Mine in Australia, although, in the past, there were deposits in a mine in India called Golconda. 

    What Makes Blue Diamonds And Blue Diamonds Jewelry Unique?

    While jewelry experts and even non-specialists will agree that blue diamonds are extraordinarily beautiful, so much so that they’re referred to as the heart of the ocean, and jewelry made from them is equally lovely. Although their beauty is not the only major reason why they’re unique. They are also not unique because of their color but because they are one of the rarest precious stones in the world.


    Blue diamonds are unique because although an average of 12-14 million carats of diamonds form every year. Out of these, only about 0.01% are fancy diamonds, the majority of these fancy diamonds are yellow, brown, black, and grey, these make about 80% of the fancy diamonds, and the meager 20% is red, blue, orange, green, purple and pink. However, in 25 years, only a paltry 50 pieces of blue diamonds have been sold.

    It is this rarity that makes them so highly sought after. Also, while some collectors choose to keep their diamonds untouched, jewelers make many of these rarities into jewelry. As the supply dwindles and natural blue diamonds become even more difficult to come across, the diamonds and some of the jewelry that has been made using them will become even more valuable. 


    Usually, blue diamond rings, necklaces, earrings, and the occasional bangle are some of the prime choices for jewelry; however, considering the rarity of the diamonds and the high demand, any piece of jewelry made out of them is usually pretty pricey.


    Not to mention that individuals or museums already own the pieces currently in circulation. Most of these owners will not be willing to let go of them. Also, the price of blue diamond jewelry is affected by factors such as the color, size, cut, and intensity of the diamond.

    In jewelry, the value of diamonds is measured in carats. And since blue diamonds are so rare, they are not always used in jewelry. But when an antique piece is made with them, it is very pricey.


    A 0.25-carat blue diamond engagement ring starts from around $2000 to $2500 apiece, and the more carats a diamond has, the more expensive it is. The intensity of the diamond is also a consideration in the cost. An intense loose blue diamond is significantly more expensive than a light, loose blue diamond.


    So, while the starting price for a 0.5 carat light loose blue diamond ring would be $50,000 or more, a 0.5 intense loose blue diamond ring would cost about $135.000, almost three times the cost of the light blue diamond.

    How Can You Obtain Blue Diamonds

    I’ve already mentioned that blue diamonds are some of the rarest diamonds ever. They’re not easy to get your hands on, as museums, and private collectors already own even the existing pieces. As such, one cannot just come across blue diamonds, and they’re not sold in stock either.


    The best way to get a piece of blue diamond jewelry would be by special order, and then you will have to know the blue diamonds price. If you want to purchase them, you have to special order them.
