What are black diamonds?

Black diamonds are opaque black diamonds that have only one color intensity: fancy black, as opposed to the color characteristics in other colored diamonds. Only two other diamond colors have similar and they are white and red diamonds. Fancy white diamonds are also opaque, although red diamonds do not have this characteristic. Other color diamonds come in a variety of color intensities, from subtle to fancy deep / dark.

Are black diamonds expensive?

Natural fancy black diamonds are relatively affordable, but it all depends on the size you want. However, cut black diamonds are much cheaper and the demand is rather low, as the majority of shoppers prefer natural ones. A natural fancy black diamond will cost anywhere from $ 3,000 to $ 5,000 per carat.

What is the origin of black diamonds?

Unlike other colored diamonds, which derive their color from geological impurities such as nitrogen, hydrogen and boron, rough black diamonds owe their color to the inclusion of graphite and random clustering throughout the diamond. Over the years, the popularity of black diamonds has grown significantly thanks to celebrities wearing black diamond jewelry.

Where do natural black diamonds come from?

Natural black diamonds are found in several regions in Brazil and Central Africa.

Are black diamonds rare?

Natural fancy black diamonds are indeed more rare than regular colorless diamonds. There are 2 types of black diamonds on the market: diamonds that acquire their natural black color during their formation deep below the earth’s surface, and diamonds that are refined (heated) to show a black color. While by no means the rarest color in nature, they are some of the most prized for their artistic beauty and dark charm, and are often included in men’s jewelry as masculine.

What are refined or cut black diamonds?

Since natural fancy black diamonds are quite rare, some cutters have begun to artificially refine low-quality colorless diamonds by heating them while in the rough until they turn opaque black. This obviously lowers the price significantly over the price of a natural fancy black diamond, but the process is completely artificial and usually does not receive a GIA certification.

How to determine the quality of black diamonds?

When it comes to natural fancy black diamonds, it is highly recommended that you purchase one that has been certified by the GIA (or other reputable laboratory) as this is the only way to know for sure if it is a natural fancy black diamond or a diamond that has been cut. From natural black diamonds, it is best to choose a stone that suits you in terms of shape / size / brilliance – as these are the most important aspects to consider. When it comes to grading natural black diamonds, the GIA provides an Identity and Origin Report, which includes color grade (black), color origin (natural), carat weight, and diamond measurement. Since it is an opaque stone, there will be no mention of purity (polish / symmetry, etc.)

What is the difference between black and white diamonds?

Black and white diamonds are almost the same, except for the fact that black is created by the incorporation of graphite into the crystal structure during diamond formation before kimberlite deposits reach the Earth’s surface. Therefore, the only difference between the two is that black diamonds have graphite inclusions while colorless diamonds do not. They are both formed by the high pressure of carbon below the Earth’s surface, which produces a repeating geometric pattern in the crystal lattice. Black diamonds are real diamonds and are almost the same as colorless diamonds except for the color.

What is the difference between black sapphires and black diamonds?

As we already know, natural black diamonds are very rare and are produced by incorporating graphite into the crystal structure during diamond formation. Black sapphires, however, are made of corundum with inclusions that evoke the color of the stone. Unlike natural black diamonds, black sapphires are found in abundance, most of which are mined in Australia.
