6 Factors for Purchasing Black Diamonds
1. A Brief History of the Black Diamond
Appreciated and known as “Fancy Black”, black diamonds have been despised in the past. According to JR Sutton’s 1928 book “Diamond: The Descriptive Treatise,” opinions on the standard black diamond being considered a gemstone vary.
Although undervalued in the past, there were some famous black diamonds, such as the Black Orlov Diamond, with 67.50 carats, which, in the past, belonged to the Russian royal family. Also known as the “Eye of Brahma”, supposedly, the Black Orlov was a 195-carat diamond that would have been part of a statue of the deity Brahma, in a temple in the Pondichery region of India. Legend has it that it was stolen by a Jesuit monk around 1800 and for that reason, it would be cursed, as most of its owners would have died by suicide.
What is known is that this stone was purchased by the jeweler Charles F. Winson and was divided into 3 smaller stones to free him from the curse. The stone now known as Black Orlov was turned into a brooch with 107 more diamonds and later into a necklace, which Dennis Petimezas purchased in 1995.
Another famous black diamond that attracted attention during the 1990s was the Spirit of De Grisogno, with its 312.24 carats. It is the biggest cut black diamond on the globe. It was found at 587 carats in Central Africa. It was later cut by the Swiss jeweler De Grisogono, known for being a specialist in black diamonds. Today, the diamond is set in a ring made of white gold, alongside 702 other diamonds.
Generally speaking, there has always been little interest in black diamonds until, in the mid-20th century, some designers began inserting black stones, along with colorless diamonds, into pieces to create a color contrast.
In the last decade, the unique beauty of black diamonds has started to catch the attention of buyers in the jewelry market.
2. What are the Characteristics of a Black Diamond?
Many people question whether black diamonds are “true”. It is possible to find a wide variety of diamond colors besides the famous and much desired colorless diamonds. Just like the pink or yellow diamond, the black diamond is, in fact, a diamond. That is, it is composed of pure carbon, just like a colorless diamond. However, black diamond has unique characteristics when compared to other types of diamonds.
The black diamond is a diamond with numerous inclusions and fractures inside. Because of this feature, it has a dark tone. These inclusions are usually made up of small pieces of graphite, pyrite and hematite. The greater the concentration of these inclusions, the darker the diamond.
The color of a black diamond can vary subtly within a spectrum that goes just beyond black. An untreated, natural black diamond can vary in color from an almost translucent grey to an olive green or dark brown.
Black diamond is slightly denser than colorless diamond. This means that if a black diamond and a clear diamond of identical size and shape are compared, the black diamond will have a higher carat weight than the clear diamond.
Black diamond generally has numerous inclusions. This characteristic is responsible for producing the black color in the diamond. However, some black diamonds have a smaller and uneven concentration of inclusions, with a less opaque surface. Because it exhibits a certain degree of transparency, it is possible to see internal characteristics such as fractures and inclusions of this type of diamond. This characteristic can be seen as a good thing or a bad thing. It will all lean on individual preference.
Generally, black diamonds are given a simpler cut, that is, with fewer facets, than most colorless diamonds are. This is because of two factors. The first is that black diamonds have many fracture points inside, which makes cutting a more delicate and laborious process. As it is a dense and opaque material, identifying the cleavage points requires a lot of skill and skill from the cutter. Therefore, the more simplified the cut, the lower the risk of damage to the jeweler.
The second factor is that because it is black and opaque, this type of diamond does not require a more complex cut, which enhances the stone’s shine, such as a brilliant cut, for example. This type of cut does not make sense in a stone that does not allow light to pass through.
Black diamonds usually have imperfections and irregularities on their surface due to the numerous fractures inside. While these characteristics are not common for clear diamonds, they are completely acceptable for black diamonds.
Generally, a good cut for black diamonds gives the stone a glossy, mirror-like surface, while the interior remains opaque. And Diamond Cut is the Most Vital Factor for Purchasing Black Diamonds.
3. Types of Black diamonds
These diamonds acquire a naturally dark tone during their formation process. These diamonds have many inclusions and cracks, which tend to make them more opaque compared to an ordinary diamond. Generally, a natural black diamond has a distinct beauty, therefore, it is rarer compared to other black diamonds on the market. For this reason, this category tends to have the highest price per carat; however, they are usually more affordable than a colorless diamond.
Most black diamonds available in the jewelry market undergo color treatment. Many of these diamonds are initially a grey, brown, or olive hue. These stones are subjected to a high temperature and low-pressure treatment, which “graffiti” the fractures, turning them into black. Artificial irradiation of colorless diamonds can also produce a green so dark that the diamond appears black.
Many people believe that carbonado and black diamond are synonymous. However, although carbonated is a type of diamond, it will hardly be used as a gemstone in jewelry. In reality, carbonate is a grouping of several diamonds that form a porous, glassy rock, similar to molten glass.
Discovered in Brazil in 1841, it was named carbonado due to its appearance similar to coal. The origin of the carbonate is uncertain. Most diamonds are found in structures called kimberlites. Carbonates are found exclusively in alluvial deposits in Brazil and the Central African Republic. There are several theories about the formation of this type of diamond with such a peculiar structure and one of them is that it would come from space through an asteroid or even the result of a supernova explosion.
4. Determining the Value of a Black Diamond
Black diamonds have an advantage over traditional diamonds: they are often cheaper than diamonds of other shades. Colorless diamonds are generally classified according to the 4 C’s GIA method, using the four criteria: Color – Color, Carat – Weight, Clarity – Purity and Cut – Cut. And this classification is responsible for determining the value of a colorless diamond.
However, it is not possible to classify black diamonds using the same criteria, after all, they are opaque and, in most cases, have many inclusions. Therefore, they cannot be rated on the GIA clarity scale used on other diamonds. As they are black, there is not an extensive color variation and, consequently, there is no classification of shades as in the case of colorless, pink and yellow diamonds. As such, the GIA does not issue grading reports for black diamonds. This type of diamond is only classified as natural or treated. Generally, natural black diamonds have a higher price per carat than diamonds that receive color treatment. If you have Intended to Purchasing Black Diamonds then Firstly Determine its Value is Necessary.
5. Care for Black Diamonds
Black diamond requires the same care as colorless diamonds. However, as it has more fractures and inclusions in its interior compared to other types of diamond, it requires extra attention in its use. Although every diamond is valued for its superior hardness, these multiple fractures and inclusions, responsible for the black diamond’s beauty, make it more vulnerable.
One of the important recommendations to avoid damaging your black diamond piece is to keep it away from sources of excessive heat and steam. Furthermore, ultrasonic cleaning is also not recommended for this type of stone.
