What You Need To Know About Black Diamonds


Meta description: Black diamonds are beautiful, yet underrated. This blog post will tell you everything you need to know about black diamonds before you purchase them. 

What comes to your mind when you think of diamonds?


Nicely cut?




Well, your first three thoughts are accurate. But diamonds come in many different colors – red, blue, yellow, and black. 


Yes, black. 

When you think of diamonds, a common image comes to mind. A big diamond placed in the middle of a ring, surrounded by tiny diamonds all around the ring. The diamonds shine brightly enough to light up a room, and the diamonds are usually white. 

But black diamonds are also popular choices for engagement rings and men’s rings. They’re also a favorite among those who collect (and love) statement jewelry.

This blog post is your guide on all things black diamonds – how they’re formed, how they’re graded, and how to determine the cost before buying them. 

How Do Black Diamonds Get Their Color?

Black diamonds get their color by mixing graphite and amorous carbon. Although they’re formed the same way as other diamonds, there are so many inclusions that give these diamonds their striking color. 

These inclusions are made up of graphite, magnetite, and hematite. Black diamonds are created under high-pressure conditions deep inside the Earth’s interior.

The way black diamonds are formed sets them apart from the other colored diamonds. They’re not as rare as pink diamonds or yellow diamonds, but black diamonds are incredibly rare regardless. 

Because they’re so rare, they’re cheaper than white diamonds. But black diamonds are becoming more popular, which is what our next section will cover. 

How Popular Are They?

Black diamonds have grown in popularity because of their unique appearance and sentimental value. They’re often used for engagement rings, as they’re often associated with romance and marital bliss. 

Back in Reinassance Italy, black diamonds were said to have the power to bring happiness back to a married couple. But nowadays they’re versatile; the lack of flashiness compared to white diamonds means that they can be used for men’s jewelry or as a statement piece.

Should I Invest In Black Diamonds?

Black diamonds cost less than other diamonds because there was not a lot of demand for them. But now that black diamonds are beginning to rise in popularity, the prices have started to climb as well.

However, the rise in demand doesn’t match up with the supply. If you see a black diamond on the market, chances are that it’s not genuine. 

  • But there’s still good news.

If you’re interested in buying a black diamond, you should look for a stone that’s decently sized and has a feature that makes it stand out. 

But here’s something to keep in mind: There’s a black market for black diamonds (haha) where they’re created in laboratories. As a result, the laboratory diamonds are cheaper but the quality is extremely low.

The Cost Of Black Diamonds

As we’ve said before, black diamonds are cheaper than colorless diamonds. 

But how cheap are they?

A fancy black diamond is between $3000 – $5000 per carat. For an engagement ring, this would be $3000. However, if you are looking for engagement rings with black diamonds you can afford, you should definitely check Itshot.

A well-cut stone will cost more than a regular black diamond. This is because it’s hard to cut a natural black diamond.

The smooth surface of a stone and its porosity (whether liquids can pass through it) also determines how much a natural black diamond will cost.

If a black diamond is treated, it becomes a lot cheaper than a natural black diamond because there’s less demand and they’re not that rare. 

A treated black diamond will set you back $300 per carat.

In Summary

These beautiful diamonds are only getting more and more popular. It’s not the striking color, the cut of the diamond, or the low price tag that contributes to its’ popularity.

It’s the versatility of black diamonds. 

Black diamonds are a popular choice for engagement rings, as well as statement jewelry pieces. But there’s not enough black diamonds to satisfy the growing demand.

That’s why if you want to buy black diamonds, you need to do your due diligence. Our experts are available for you to make the best choice.

That way, you can be sure that the black diamonds you’re buying are high-quality and well-priced.
