One thing that can be noticed is that fancy colored diamonds are often preferred by many people because of their high rarity. Similar to the pink diamond that Jemmia Diamond mentioned in previous articles, black diamonds are also a very unique and rare type of colored diamond. So what makes them so unique? Let’s explore the following content with Jemmia Diamond.

Why is a diamond black?

Black diamonds are a type of diamond with a high amount of inclusions. Although the inclusions on a normal white or colorless diamond may appear as small black spots, when they appear at an extremely high level, the diamond turns completely black. From there, black diamonds are formed.

Why are black diamonds often used for engagement rings?

Because of the uniqueness and rarity that black diamonds possess, many people choose them as a very classy engagement token, because when made into jewelry, it may be “one of a kind”.

Black diamonds not only bring high economic value but also offer great aesthetic value. When you own them, you will look truly luxurious and classy.

A typical example is a 7.6ct emerald-cut black diamond from Hong Kong, kept in a museum where the beauty it possesses can be displayed. This is a completely unique creation. As Myleen said: “There is only one such diamond in the world!”

Because of the uniqueness and rarity that black diamonds possess, many people choose them as a very classy engagement token, because when made into jewelry, it may be “one of a kind”.

How many types of black diamonds are there?

Black diamonds are classified into 2 main types, including: natural black diamonds and diamonds that have been treated to become black. Like most gemstones, the first type – naturally black diamonds – has extremely high value because it belongs to nature.

It is also easy to see that treated black diamonds will have lower value compared to natural black diamonds.

The color  of these natural black diamonds comes entirely naturally; it is their inclusions that form graphite clusters, causing the stone to have a metallic black color.

The way black diamonds form in nature makes them rarer and increases their value much more than artificially treated black diamonds.

Black diamonds are often combined with metals such as 14k white gold and platinum, helping to highlight the diamond’s color. They are also often set next to colorless diamonds as a way to create visual contrast.

What makes black diamonds unique?

Below are some things that make black diamonds unique:

  • Black diamonds have a mysterious black color, creating allure for their owners and those who admire them.
  • Black diamonds are slightly different from other colored diamonds, because they consist of many small crystals connected together in a random pattern.
  • A pure black diamond, due to containing a high carbon content inside, has its color altered – this helps make it a perfect and valuable gemstone.
  • Black diamonds can also be made into many different types of jewelry, enhancing luxury and class, and in the long run, a black diamond will increase in value if you know how to preserve it.

When it comes to black diamonds, it is important to distinguish between natural stones and stones treated to become black.

When choosing to buy black diamonds, being clear-headed in distinguishing their origin is the decisive factor. You need to pay special attention: natural black diamonds always have a value many times higher than color-treated diamonds. Usually, cheap black diamonds on the market are mostly white diamonds with low clarity, treated with heat or irradiation to change color. In contrast, natural black diamonds (also known as Carbonado) possess an original beauty from millions of years ago, making them a treasured gem sought after by connoisseurs.
