Two Types of Black Diamonds

There are two types of black diamonds in the market. The majority are natural treated diamonds, which mean they were mined from the earth and irradiated, or exposed to a strong 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.

Natural Fancy Color

Pear Shaped Black DiamondIn a natural fancy color black diamond, the color is caused by the presence of 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 the very thing that 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

Standard Color Enhanced Black DiamondColor enhanced black diamonds are also an available option. These are natural diamonds that have been irradiated to give them color. Unlike natural fancy color black diamonds, the clarity of treated black diamonds does vary.

Almost completely opaque and nearly pure black in appearance, the beauty and affordability of these stones makes these an ideal choice for both bridal and fashion jewelry.

Black Diamond History

  Large Emerald Cut Black Diamond

Famous Black Diamonds

Called "Sergio” the largest diamond ever found came from Brazil and weighs in at an impressive 3,167 carats, or about 1.4 pounds

Seen for the last time in Tokyo in 1971, the Black Star of Africa is a massive 202 carats.

The Star of Islam is an emerald cut diamond weighing 160.18 carats.

The most famous of all is the Black Orlov diamond. It weighed 195 carats in the rough. Beautifully cut and polished to a faceted, cushion-shaped gem, the Black Orlov still weighs a very respectable 67.5 carats.

Black Diamond Lore

As a real, natural diamond, these stones share all of the same meanings and symbolism as traditional white diamonds, such as strength, wisdom, eternity, and everlasting love. Italians in medieval times believed that black diamonds wielded the power to restore the relationship of a married couple, and the Black Orlov diamond had a reputation for bestowing happiness and good fortune on anyone who touched it.

Assessing Black Diamond Quality

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 that should be taken into consideration when selecting your black diamond. The numerous inclusions occurring in a dense concentration makes cutting these diamonds difficult and can result in the presence of small cavities and interconnecting feathers that reach the surface. To ensure that your black diamond is a beautiful, high-quality stone, take care to look closely at the surface, paying particular attention to the table and table facets. A well-polished black diamond will have a smooth surface with no visible blemishes.
