A Guide for Buyers & Investors


Natural fancy black diamonds are among the rarest color diamonds on the market. For this reason, the majority of black diamonds available have been treated to enhance their color. In terms of origin, appearance and the basis on which they are graded, natural fancy black diamonds are most dissimilar to all other classes of colored diamonds. Unlike traditional color diamonds, which are translucent, fancy black diamonds naturally exist only in black and without any secondary color modifiers.


Diamond Envy’s team of experts is made up of GIA Graduate Gemologists, artists, activists and diamond enthusiasts with experience in every step of the supply chain. Our involvement in each step also allows us to pass along the most exquisite, conflict-free diamonds and jewelry at competitive prices.


Each diamond is hand selected by our graders whom evaluate them based on cut, color and clarity to ensure our collection offers the most beauty and value.  Black diamonds are a mysterious breed that fascinates and amazes us. You can see for yourself some of the gorgeous black diamonds we’ve purchased over the last few years that we sell today.  We share the impressive qualities of natural black diamonds below.




Natural fancy black diamonds derive their color from the aggregation and even distribution of a massive amount of dark inclusions. The collection of such inclusions imbues natural black diamonds with their characteristic black color. Unlike white, or colorless, diamonds and their color diamond counterparts, natural fancy black diamonds absorb, rather than reflect and refract, light. This unique property of natural black diamonds gives them their opaque appearance. Brilliance and light performance are noticeably absent in fancy black diamonds and are instead supplanted by a uniformly glossy surface.


Because of the dark opaque nature of natural black diamonds, the usual characteristics of fancy color diamonds, such as color intensity, secondary color modifiers, tone, fluorescence and clarity, are not applicable. The Gemological Institute of America (GIA) grades natural fancy black diamonds only for shape and cutting style, measurements, weight, color origin, grade and distribution. These attributes are detailed in a particular type of report referred to as a “Colored Diamond Identification and Origin Report” by the GIA. Other fancy colored diamonds that are submitted to the GIA for a comprehensive grading report, including clarity, inclusion diagrams, and proportions, will be issued a “Colored Diamond Grading Report.”

Since color intensity and saturation are irrelevant in the appearance and valuation of natural fancy black diamonds, this type of fancy color diamond is cut into all shapes possible, including the round cut. The likelihood of finding a fancy black diamond in one’s preferred shape is rather high, thus making fancy black diamonds a fine color choice.

Although natural fancy black diamonds command a higher price than their treated counterparts, they nonetheless cost substantially less than most natural fancy color diamonds of comparable weight. While natural black diamonds are actually extremely rare, when available, they offer a more affordable option for consumers who want a fancy color diamond without breaking the bank.  Black diamond price is currently similar to that of colorless diamonds but the natural black diamonds value is expected to rise.




Black diamonds are the least understood of all classes of colored diamonds. As mysterious as their physical appearance is, their origin and background are even more so. Natural black diamonds, or carbonados, bear little resemblance, chemically and physically, to other colored diamonds. The large amount of hydrogen in their chemical composition hints at otherworldly beginnings. Carbonados are the most ancient and hardest of all diamonds and are few and far between.


The Portuguese of Brazil named black diamonds “carbonado,” meaning carbonized or burnt, in the mid-1700s due to its physical similarity to porous charcoal. Because of their hardness, natural black diamonds can be cut only with another black diamond. They owe their tough build to their makeup, which consists of millions of crystals cohering as a unit. Conversely, traditional diamonds are cut from one crystal that readily splits upon a common axis. Before they found their modern use as glittering mystical gems, carbonados were initially employed in polishing hardwood in Brazil. In the early 20th century, they were repurposed to drill rocks in the building of the Panama Canal.


While traditional diamonds were conceived hundreds of miles within the earth and emerged via a pair of volcanic eruptions between a billion and 100 million years ago, carbonados have been identified as being older than 3.8 billion years. This leads scientists to believe that natural black diamonds did not get the same start as their traditional counterparts. Although the bulk of diamonds practically covers the whole planet, fancy black diamonds, on the other hand, have roots only in Brazil and the Central African Republic.


For these reasons, scientists believe black diamonds hail from outer space, the result of a star’s explosion, known as a supernova, which occurred ages ago. They reached earth as part of an enormous diamond-rich asteroid that fell onto our planet as stellar fragments besieged both earth and moon billions of years ago.


Famous Black Diamonds


The Black Orlov: this 67.50 carat black diamond, also referred to as the Eye of Brahma diamond, originated in the early 19th century in India. Folklore dictates that this diamond, which had a rough weight of 195 carats, endured as an eye in a statue of the Hindu god Brahma before a monk spirited away the precious jewel. The defilement allegedly put a curse on the diamond that would cause a rash of suicides among its future owners, including Russian princess Nadia Vyegin-Orlov, the inspiration for the diamond’s name. The last known owner of the Black Orlov was J. Dennis Petimezas, a diamond dealer, who purchased the diamond in 2004 for an undisclosed amount.

This mogul-cut diamond started out at a rough weight of 587 carats in western Central Africa and was then transported to Switzerland to be cut by Swiss jeweler De Grisogono in the traditional Mogul diamond cutting style.
