Reasons to Choose a Black Diamond Engagement Ring

The Portuguese refer to black diamonds as “carbonados”. Black diamonds are the same mineral as all other diamonds and are sourced from areas like Brazil and Africa. These diamonds consist of graphite and other minerals and work with light differently than other diamonds.

Black diamonds begin their life in colourless form, with a low clarity rating. Once they have been heat-treated or gone through the irradiation process, they become much darker.

In recent years, black diamond rings have become a popular choice for engagements for many reasons:


Health and Wealth

Diamonds are also strongly linked to wellness and affluence. Many people who wear diamonds feel more protected from evil forces. Diamonds continue to be enduring symbols of love. Black diamonds are regarded as elegant, mysterious and highly exquisite. They allow people to make powerful statements that are hard to ignore and have become more popular over time.

Uniquely Composed

Another great reason for investing in black diamonds is their unique composition of materials like amorphous carbon and graphite. They tend to be sourced from relatively recent rock formations near natural water sources. Because of their unique composition, black diamonds are one of the hardest materials on earth, making them an excellent choice for fine jewellery.

A Durable Option

Black diamonds are exceptionally tough, measuring 10 on the Mohs Hardness Scale. This makes them extremely hard to cut, which means experienced professional diamond cutters are required to complete the job successfully. In the past, some people thought of black diamonds as unlucky, but this is now rarely the case. They are now widely regarded as excitingly mysterious and incredibly elegant.



The History of Black Diamonds

Black diamonds aren’t for everyone, but some people love this enduring colour. We can supply you with various types of black diamond rings, including princess cut rings and many more. People opt for diamonds when seeking out engagement rings for many reasons.

Diamonds represent themes like power and prosperity. In ancient Egypt, diamonds represented the sun, truth and courage. Greeks saw diamonds as the tears of Gods, and those that owned them were said to be blessed. In some territories and periods, diamonds have even been thought to have healing powers.



Beliefs About Diamonds

In ancient India, diamonds were believed to protect people from evil. Many were reluctant to cut diamonds because they thought this power would be lost. Mediaeval Europeans also thought diamonds represented protection from evil.

Although colourless diamonds may immediately spring to mind when you think of diamonds, black diamonds have become incredibly popular over the generations.

Powerful Emotional Meaning

Many people believe that diamonds have a deep emotional meaning. One of the most common uses for diamonds is to gift them to partners during proposals. Black diamonds are strongly associated with inner strength.

Many people use black diamond engagement rings to represent the love felt between themselves and their partners and celebrate the strength of their relationships.

Black Diamond Engagement Ring FAQs


A black diamond ring is a luxurious and unique piece of jewellery with many meanings. For some, it is a symbol of elegance and sophistication, while for others, it represents strength and power. Regardless of its personal significance, a black diamond ring is sure to turn heads and make a statement.


Black diamonds are found in many different places around the world, including Brazil, India and Africa. They are typically one of the rarest and most expensive diamonds on the market. In addition to their rarity, black diamonds are also prized for their hardness and durability. As a result, they are often used in engagement rings and other fine jewellery.


Black diamonds are some of the rarest and most valuable diamonds in the world. Also known as carbonado diamonds, these stones are only found in a few places on earth, and they typically command high prices when they come up for sale. Interestingly, black diamonds get their colour from the high levels of carbon impurities in the stone. This gives them a unique appearance that differs from the traditional white diamond. While black diamonds are not as popular as white diamonds, they are still highly sought-after by collectors and those who appreciate rare gemstones.


Most black diamonds on the market are actually dark grey, but truly black diamonds are incredibly rare. Due to their scarcity, they are often used in high-end jewellery and command a significant premium. However, some people question whether black diamonds are real. It is possible to create fake black diamonds using irradiation and annealing, but these treatments are typically detectable by gemologists. As a result, most black diamonds on the market are likely to be real. Nevertheless, their rarity means that they will always be in high demand among collectors and jewellers alike.
