3.62 Carat Genuine Black Diamond 14K Yellow Gold Ring

Black diamonds are one of the most popular colored diamonds. In fact, as the popularity of nontraditional engagement rings has risen, the demand for these magnificent stones has skyrocketed, and for good reason, as I’ll explain momentarily.

Demand for black diamonds is increasing.

Black diamonds are in high demand.

But first and foremost, despite the fact that black diamonds are quite popular, there is a lot of disinformation and misperception around them. I’ll begin by addressing the most fundamental of all questions:

Are Black Diamonds Genuine?

Whether you’re wondering if there are black diamonds, the answer is yes – black diamonds exist!

Black diamonds, on the other hand, come in a variety of shapes and sizes. There are three types of black diamonds: man-made black diamonds, natural black diamonds, and treated black diamonds. All are genuine diamonds, but there is a significant difference between the various varieties of black diamonds, and if you want to purchase one, you should be aware that there is also a significant variation in value.

Keeping this in mind…

What Exactly Are Black Diamonds?

Though this seems to be a simple and straightforward topic, asking various professionals in the diamond business “what is a black diamond?” would get a variety of replies.

The truth is that there are three types of black diamonds and three prices for black diamonds: natural black diamonds – also known as fancy black diamonds and Carbonados – man-made black diamonds, and treated black diamonds, which are the ones most people refer to when looking for black diamonds – even if they are unaware of it. I’ll go through the distinctions between the types:

There are three types of black diamonds:

Natural black diamonds are not the same as other colored diamonds. A black diamond is an impure type of polycrystalline diamond composed of diamond, graphite, and amorphous carbon, according to the “dry” explanation. It’s not really obvious…

In other words, whereas “regular” natural colored diamonds get their color from impurities attached to them during the formation process (for example, boron causes blue diamonds), black diamonds are similar to white diamonds in that they have an extremely high amount of inclusions, clusters of graphite inside of them to the point where they simply appear black.

Treated black diamonds are ordinary white diamonds that are often exceedingly low in value owing to a significant concentration of imperfections. Because they contain so many inclusions, they can only be used as industrial-grade444 diamonds as white diamonds with the use of treatments like irradiation or heat.

In some ways, “colorless treated black diamonds” or simply “black colored diamonds” is a more appropriate moniker for these gems (which I’ve heard used many times). Because “useless” white diamonds are utilized in the manufacturing of this form of black diamond, it is the cheapest sort of black diamond.

Lab Grown

Man-made / lab-grown / synthetic / simulated black diamonds are not diamonds in the traditional sense. While they seem to be more or less the same to me, I suspect others that deal with these kinds of diamonds would disagree (and would be very angered with me).

All of them are often referred to as fake, although there is a significant distinction between them. To be honest, there is a significant difference between them.

Lab-produced diamonds are, in some ways, hi-tech firms, and although treated diamonds are much less expensive than conventional diamonds, lab-generated diamonds are still not as inexpensive. The reason for this is that there are a lot of research costs, large and costly equipment, and manpower.


This is why, although there is a market for lab-grown blue and pink diamonds, there is none for lab-grown brown or black diamonds – it makes no economic sense. Natural blue and pink diamonds cost tens of thousands, if not hundreds of thousands, of dollars per carat, whereas brown or black diamonds cost between $2,000 and $3,000 per carat.

I did explore the topic of “man-made black diamonds” since I know it is looked for and written about, but to be honest, I have never found one – most likely because it is not economically feasible to manufacture. Furthermore, like with other high-tech items, their costs are always decreasing as technology advances.

Simulants and synthetics, on the other hand, are virtually as cheap as purchasing cubic zirconia and can be found “a dime a dozen.” You should not purchase them if you are seeking black diamonds, but you should be aware of them and keep an eye out for them.
