What are black diamonds?

Dark and dramatic, black diamonds make a wonderful choice for engagement rings, wedding rings, earrings, and more. Black diamonds are fancy color diamonds, however, they are much more affordable than other fancy color diamonds such as pink and blue diamonds. These opaque diamonds have no sparkle. Instead, they have a high luster. Because they are opaque, the GIA cannot assign them a clarity grade.

Are black diamonds real?

There are naturally occurring black diamonds as well as treated black diamonds. Because black diamonds are so rare, they are often treated to become black. Treated (also called enhanced) black diamonds are man-made by taking white diamonds that have too many inclusions to use for jewelry. The diamonds are then heated or irradiated to obtain a dark color. Color treated black diamonds are actually an incredibly dark green color, but appear black in regular lighting. A GIA certification will specify if a diamond is natural or color treated. At Ritani, we only use natural black diamonds in our jewelry.

How are black diamonds made?

Black diamonds are formed the same way colorless diamonds are formed: from pure carbon, intense heat and pressure under the earth’s surface. Fancy black diamonds receive their dark color from large amounts of mineral inclusions such as graphite, hematite, or pyrite. Because they are so heavily included, they must be cut, polished, and set with care in order to not damage the diamond.
Black diamonds can feature microscopic fractures as a result of being so heavily included. These fractures can make your diamond more vulnerable to cracking. It’s recommended that you do not use ultrasonic cleaners for black diamond jewelry, which can damage black diamonds.

How much are black diamonds worth?

Even though black diamonds are rare, they are generally less expensive than colorless diamonds. This is because they are in far less demand than colorless diamonds.

There aren’t any official guidelines as to how much a black diamond should cost, but a natural fancy black diamond will generally cost from $2,000 to $3,000 per carat.

Be wary of inexpensive black diamonds. If you stumble upon an inexpensive black diamond, it was likely color treated. As the old saying goes, if it’s too good to be true, then it probably is.
