A gorgeous black diamond ring with sidestones and paved shanks – Leibish.
In recent years, black diamonds have grown greatly in popularity and are used in a wide variety of jewelry. Thanks to their bold, unique appearance and endorsements by celebrities, they have been elevated from cast-asides into starring roles.
In this write-up, we will do a deep dive into the world of black diamonds. You will find out what they are, the symbolic meaning they represent and interesting facts about them. I will also reveal the 3 most important things you need to know before shopping for a black diamond and the best places to buy one.
Let’s jump right in…
Here is a list of topics we will be covering:
A natural color black diamond is also known as a carbonado, which is a Portuguese term for opaque, dark diamond. From a gemological standpoint, a carbonado is a raw form of polycrystalline diamond that is composed of amorphous carbon, graphite and diamond.
If that sounds too technical to understand, you can simply think of a black diamond as a big clump of diamond dirt where a mish-mash of graphite, carbon and diamond crystals are grown together.
Compared to other colored diamonds, black diamonds do not get their color from chemical impurities (e.g. nitrogen impurities cause yellow tints while boron causes blue hues) in their crystalline structure. Instead, naturally black diamonds get their color from the massive amounts of mineral inclusions that extend throughout the entire stone.
Because of their opaque nature, black diamonds do not display the sparkle or brilliance that we normally associate a diamond with. Instead, they display an “adamantine” luster which gives them a shiny appearance.

It is believed that black diamonds were a form of protection from evil and carbonados had cleansing powers to remove bad luck. In some societies, these dark gems were also viewed as a communication tool between the spiritual and physical world.
Some people also believe that black diamonds symbolize charisma and had powers to help you shape your future. In this regard, black diamonds are also connected with inner strength and passion.
In Asian culture, the color black is often associated with bad luck and death. As you can imagine, black diamond jewelry isn’t that well received in this part of the world. At the end of the day, whether a black diamond has a positive or negative meaning really depends on the society we live in.
Compared to other fancy colored diamonds with pink or green hues, black diamonds aren’t as rare but that doesn’t mean that these are stones that are easily found in mines around the world. In fact, natural black diamonds are only found in Brazil and central Africa.
This may come as a surprise since black diamonds are often classified as low quality industrial diamonds (bort) that are abundant in nature. However, diamonds (carbonado) that have an extremely high amount of inclusions and clusters of graphite are relatively rare compared to colorless diamonds.
When it comes to prices, it largely boils down to demand and supply. In the market, there are 2 types of black diamonds that you will come across – natural or treated black diamonds.
Most of the black diamonds that are sold are often heat-treated and these diamonds are extremely cheap. You can easily get a 1 carat enhanced black diamond for as low as $100 to $200 per carat.
In contrast, natural black diamonds that are certified by GIA can fetch prices between $1,000 to $3,000 per carat depending on its carat weight. This makes them an affordable alternative to colorless diamonds which can cost a lot more depending on the quality of the 4Cs.
#1 No one can agree on how they were formed – While colorless diamonds can be found on every continent, black diamonds are only found in 2 parts of the world: Brazil and Central Africa. Due to their limited locations in alluvial deposits, scientists and geologists are divided over their origins.
Three of the most compelling theories involve the remnants of asteroids that hit the Earth’s surface, irradiation and special formation conditions deep within the Earth that black diamonds are created.
#2 They are tougher than normal diamonds – Carbonado’s polycrystalline structure allows it to endure higher stress and prevent cleavage compared to a normal diamond. Cutting tools that are made with black diamonds have better lifespans and are suitable for high performance grinding applications.
#3 They absorb light instead of reflecting it – Black diamonds are more porous than other types of diamonds and their polycrystalline structures cause them to absorb light instead of reflecting it.
#4 They’ve become popular with men – Due to their bold, striking look, black diamond jewelry have a very contrasted look that makes them stand out and increasingly popular with men. Justin Bieber is the latest celebrity who was seen wearing black diamond earring studs.
Black diamonds have always captivated people around the world because of their dark, mysterious looking color. Check out the top 5 most spectacular and historically important stones below.
#1 Black Orlov – Perhaps the most famous black gemstone of all time, the Black Orlov is a 67.50 carat cushion cut diamond that was believed to be cursed. Legend has it that the Black Orlov was carved out from a sacred statue in a Hindu temple located in South India.
Three previous owners including a Russian princess called Nadia Vyegin-Orlov jumped to their deaths mysteriously. The curse was eventually broken when Charles Winson bought the diamond and had it cut into smaller pieces.
#2 Spirit of de Grisogono Diamond – The world’s largest polished black diamond that weighs in at a hefty 312.24ct. The Spirit of de Grisogono Diamond is named after the Swiss cutter who polished the diamond. It is fashioned in an old Moghul-cutting style and is mounted in a splendid white gold ring that resembles a large ice-cream cone.
#3 Korloff Noir Diamond – This gorgeously stunning 57 facet black gem weighs in at 88 carats and is currently owned by the Korloff company in Paris. The legendary diamond is reputed to bring happiness, good luck and prosperity to people who have come into contact with it.
#4 The Rembrandt – Cut from a 125-carat rough diamond, the Rembrandt diamond too more than 3 years to cut and polish. The final polished stone weighs in at 42.27 carats and was presented by Rembrandt specialist Gary Schwartz. The diamond is currently in the possession of the Diamant Museum Amsterdam where it is on display.
Evaluating and choosing a black diamond to purchase is more of an art rather than a science. Similar to other types of diamonds, there are a variety of shapes that black diamonds are cut to and there is a lot of subjective preferences involved in a selection.
Personally speaking, there are 3 important things I look out for when buying a black diamond.
A large feather (crack) that extends inward from the girdle.
#1 Surface reaching inclusions – Black diamonds are inherently full of inclusions and because of this, cutting and polishing them can be difficult. In fact, it is almost impossible to achieve a high level of smooth polish because of the inclusions present.
It is common to see facets that are pitted or covered with polish drag lines due to the abundance of cleavages, factures and inclusions that break to the surface of the diamonds. If these surface-reaching inclusions are minute, they shouldn’t pose a problem.

However, when there are large feathers or cracks along the girdle of the diamond, it could become vulnerable to chipping and I would generally avoid such stones. Diamonds with a significant amount of polish drag lines should also be avoided as it affects luster negatively.
Fancy black diamonds can come in different variations and appearances.
#2 Internal characteristics – When judging the quality of a black diamond engagement ring, you can’t use the same criteria of the 4Cs as colorless diamonds. Traditionally, people tend to prefer “less color” and “better clarity” in a colorless diamond engagement ring but the opposite is true for black diamond rings.
For fancy color diamonds, more color is generally better and the color distribution should ideally be even throughout the stone. And this is where the internal characteristics of a fancy black diamond come into play.
Natural black diamonds can look uniquely different from one to the other depending on the specific type of inclusions it has and how it was polished. This leads to a wide range of appearances like opaque, smoky, semi-transparent, or even having inclusions that stand out from the dark contrasting hue.
Personally speaking, I tend to prefer black diamonds that are opaque and look uniformly dark. If a diamond had a big amount of inclusions that are too whitish, it can create a non-uniform appearance that I find distracting.
#3 Reliable grading report – The vast majority of black diamonds that are used in jewelry and engagement rings are heat-treated to give them a dark looking appearance. Most of these heavily included diamonds start off as gray/white color before undergoing high temperatures to graphitize their inclusions.
The GIA Identification and Origin report will provide assurance that you are buying a real, natural black diamond.
If you are looking for a real, natural fancy black diamond, you should only buy one that comes with a GIA certificate. Don’t believe anyone who claims to be selling a real black diamond (regardless of any marketing fluff they claim) if it doesn’t have reliable documentation and assessment from GIA.
In fact, a common scam that unethical jewelers use is to provide a dubious report or claim that the stone you are buying is a “natural diamond”. It’s a play with words because it refers to a naturally mined diamond that is treated to take on a black color hue.
Don’t get me wrong. There’s nothing wrong with buying an irradiated or heat treated diamond as long as the enhancements are disclosed in a transparent manner. The prices should realistically reflect the type of diamond you are buying and you shouldn’t overpay for an enhanced diamond.
There are several reasons why black diamond engagement rings have been gaining popularity with buyers. Not only do they offer a bold and unique looking variation of popular white diamond rings, but they are also significantly less expensive!
In my opinion, a black diamond engagement ring garners a lot of attention because of the fantastic contrast it creates with a white metal setting. The combination of a black center stone and white color melee diamonds can also lead to creative and striking results.

Natural fancy black diamonds are relatively rare compared to other fancy color diamonds and you will seldom see them being sold in physical retailers or even on some of the bigger online vendors.
As a consumer, the biggest problem you are going to face is telling the difference between a natural and a treated diamond. The visual differences are difficult to tell apart even for a more seasoned buyer and it doesn’t help that the majority of black diamonds in the market are enhanced.

In my opinion, the best place to buy natural fancy black diamonds is Leibish & Co. This is a vendor that specializes in fancy color diamonds and have a superb selection of GIA certified diamonds.
