There are two types of black diamonds on the market. The majority are natural treated diamonds, which means they were mined from the earth and irradiated, or exposed to an intense radioactive and heat treatment that darkens the stone’s color. 

The second type of black diamond is natural, untreated, which means the stone isn’t subjected to any irradiation. As a result, the diamond isn’t completely opaque; you can look through it and see the beautiful inclusions. Despite the areas of transparency, however, the stone will appear mostly black to the naked eye. Natural, untreated black diamonds are somewhat rare, but you can expect to pay much more than the treated version.

In a natural fancy black diamond, the color is caused by numerous inclusions in a dense concentration. These characteristic inclusions consist primarily of graphite, as well as traces of magnetite and hematite. Because the inclusions are what give these diamonds their color, natural fancy-colored black diamonds do not receive clarity grades.

While these diamonds are mostly opaque, transparent areas between inclusions can often be seen when light shines through the diamond. These areas typically appear brown but may be any pale color.

Color-enhanced black diamonds are also available. These are natural diamonds that have been irradiated to give them color. Unlike natural fancy-color black diamonds, the clarity of treated black diamonds varies.

Almost entirely opaque and nearly pure black in appearance, these stones are both beautiful and affordable, making them an ideal choice for both bridal and fashion jewelry.

Because of the high number of inclusions present in natural fancy color black diamonds, clarity is not a factor in determining the quality and value. Instead, the cut and polish are the main traits to consider when selecting your black diamond.

The numerous inclusions in a dense concentration make cutting these diamonds difficult and can result in small cavities and interconnecting feathers that reach the surface.

To ensure your black diamond is a beautiful, high-quality stone, look closely at its surface, paying particular attention to the table and table facets. A well-polished black diamond will have a smooth surface with no visible blemishes.

Famous Black Diamonds

Called "Sergio,” the largest diamond ever found came from Brazil and weighs an impressive 3,167 carats (about 1.4 pounds).

Black Diamond Lore

As real, natural diamonds, these stones share the same meanings and symbolism as traditional white diamonds, such as strength, wisdom, eternity, and everlasting love. In medieval times, Italians believed that black diamonds could restore a married couple's relationship, and the Black Orlov diamond was known for bestowing happiness and good fortune on anyone who touched it.
