What geology and gemology think about this is interesting. First, on the Moon, and then on Earth, in places of volcanic, meteorite and even nuclear explosions, black diamonds are found in nature. It is extremely unusual: it has the simple structure of graphite, but the properties of diamond. Nature, as it should be, sets riddles for man. This is just one of the assumptions. Black diamond is a mystical secret. There is a hypothesis that this is cosmogenic diamond dust. Glass is cut with these diamonds like plain paper with scissors. In Russia, in the mines of the village of Kartun (Primorye, Far East), small non-jewelry black diamonds were discovered. Their black color depends on trace elements - nitrogen, boron and hydrogen. It is these elements that are considered cosmic inclusions.
There are other hypotheses
In the depths of the Earth, where the highest pressure and temperature, carbon atoms turned into black diamonds due to inclusions of hematite or graphite.
Another theory suggests that the black color is due to a breakdown in the diamond lattice.
That is, there is no unified theory of the origin of a natural, natural black diamond. But meanwhile - it's really a diamond,only of a different nature: a black diamond does not reflect, does not refract light, like ordinary white ones, but only absorbs it. It is this quality that makes it black. When the question arises: “What is the name of a black diamond?”, The correct answer is carbonado.
Where industrial developments take place
Deposits of jewelry black diamonds are found only in Brazil and Africa, once connected by one ancient continent - Pangea, but not at all in those places where conventional diamonds are mined. In the 18th century, the Portuguese called it "carbonados", which means "burning" or "burnt". There is another version of the origin of this name. It is associated with porous black charcoal, which is similar to raw stone. This is what a rough black diamond looks like (photo).

Processing
There are two types of black diamonds: dense and porous. The first type is rarer and allows it to be cut and polished better. The quality of the diamond is noticeably higher. In addition, some of the stones do not have a black color. It can be uneven, from dark brown to dark gray. But they are all classified as black diamonds.
Some gemologists do not consider black diamonds to be diamonds. However, the name "black diamond" is firmly established in the trade, and everyone is used to it.
But natural, natural black diamonds are extremely rare. They, in contrast to the processed diamond, the color will be uniformly black. There are no tints or stains. Butblack diamond, for all its rarity and attractiveness, does not have such brilliance and radiance as ordinary transparent diamonds. It does not scatter light. But the graphite, which is part of it, absorbs light and gives the stone color and shine.
Only a special cut allows you to get a brilliant shining brilliant from a black diamond. But this is a very painstaking work, because in not very experienced hands, the black diamond begins to crumble. So cutting and subsequent polishing greatly affect its appearance. Only the facets of a diamond reflect light, not all of it. It is the edges that will shine and sparkle. The consistency and clarity of the application of the edges is very important.
Only the right processing will make the black diamond glow fiery. The stone will play.
Cost
The price of black diamonds is lower than ordinary, transparent ones, and all because black diamonds are obtained from low-quality transparent diamonds in large enough quantities. A well-polished round black diamond costs $1400-1700. It does not have any defects. Black diamond is a very ancient stone, but only relatively recently, in the twentieth century, it began to be appreciated in the jewelry market. Therefore, the prices for black artificial diamonds are noticeably lower. Weight, color and cut are indicators of quality. They make up the price. The price of one carat can start from $1,000 and go up to one and a half thousand. Of course, buying an elite stone is not cheap, but it has become available not only to people of blood. A wide range of products willchoose jewelry for the soul and people of average income.
This stone has become fashionable. Marketing companies are working to "spin" the black diamond, and its prices are gradually rising. It depends on the suppliers, their stocks and market demand.
Evaluation of the quality of artificial black diamond
It is necessary to inspect all the edges and make sure that there are no chips, pores or scratches on them.
In addition to the certificate, laser engraving of the certificate number inside the stone can serve as a guarantee of quality.
In jewelry
Black diamond dazzles with its beauty, especially in combination with white diamonds. Black, satin sheen stone is good in itself. But when framed by sparkling diamonds, the jewelry makes a stunning impression.
It is no coincidence that they are acquired by creative people, as well as business, restrained men. They are magnificent when framed in pink and especially white gold, the brilliance of which they emphasize. But they are also good in silver. Earrings, rings, bracelets are made from them. Any woman will be able to choose what will emphasize her attractiveness more. These can be modest accessories that unobtrusively place accents, but a catchy bright thing is also possible, from which it will be impossible to look away.
Black diamond ring
Like no other stone, a black diamond suits men. A ring with a black diamond looks courageous and noble on a man's hand and goes well with evening suits.
The image of a man becomes strict and luxurious at the same time. Aristocracy is revealed, as well as the fact that its owner has a pronounced personality.
For a woman of any age, a black diamond ring will emphasize her exquisite taste and style, add subtle femininity, fragility and insecurity, grace.
Flickering space on the finger - what could be more poetic? Today it has become customary to make wedding rings with black diamonds. Usually in the center there is one large black diamond, which is surrounded by smaller transparent diamonds. Any piece of black diamond jewelry is the most beautiful accessory you can dream of, emphasizing the style and excellent taste of its owner. Any ring design will attract respectful attention as it looks organic with any style.
Evening attire, formal business suit, black&white cocktail dress – everything is in perfect harmony with the ring. Business meeting or office work - the ring is appropriate everywhere.
Refined diamonds
As the popularity of natural black diamonds is growing and there is not enough natural black diamonds, refined diamonds are entering the market. They are mined in the same mines where ordinary diamonds are mined.
Only a few countries have the technology to create jewelry black diamonds. In Israel and Italy, laser processing is performed, cutting is done again in Israel and more.in Belgium. In Israel, there are technologies to improve the clarity of an ordinary diamond. Those inclusions that are in the stones become invisible. They are almost invisible to the eye. Only a specialist (jeweler or gemologist) will determine which stone is in front of him. And the visible result is a clean sparkling stone. At the same time, the cost of artificial diamonds in comparison with natural diamonds falls by more than half. Due to the elimination of small voids by the laser method, the light passes through the entire diamond from the bottom up. As a result, the stone "plays" and shines beautifully.
Improve the color of a diamond
To get a perfectly black diamond, diamonds with defects are used, which will then hide the black color. Therefore, their cost can fluctuate very sharply: from $100 to several thousand per carat. Too much depends not only on the quality of the laser-cut stone, but also on cutting and polishing. The certificate and guarantee of such a stone always indicates how the stone is processed, but never its price.
Gemstones give rise to both desires and lusts, and carry madness, entail death and crown love stories.
