Black diamond in nature. What is the name of a black diamond? Ring with a black diamond

What is geology and gemology thinking about this is interesting. First, on the Moon, and then on Earth in places of volcanic, meteoric and even nuclear explosions, they discover a black diamond in nature. It is extremely unusual: it has a simple graphite structure, but the properties of a diamond. Nature, as it should, gives riddles to man. This is only one of the assumptions. Black diamond is a mystical mystery. There is a hypothesis that this is a cosmogenic diamond dust. Glass is cut with these diamonds, like a plain paper with scissors. In Russia, small non-jewelry black diamonds were found in the mines of the village of Kartun (Primorye, Far East). Their black color depends on microelements - 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 were transformed due to inclusions of hematite or graphite into black diamonds.

Another theory suggests that black appeared due to a break in the lattice of the diamond.

That is, there is no single theory of the origin of natural, natural black diamond. But meanwhile - it's really a diamond, just of a different nature: a black diamond does not reflect, does not refract light like ordinary white, but only absorbs it. It is this quality that makes it black. When the question arises: "What is the name of a black diamond?", Then the correct answer is carbonado.

Where is the industrial development

Deposits of jewelry black diamonds are available only in Brazil and Africa once connected by one ancient continent - Pangea, but not at all in places where ordinary 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 coal, which looks like an unprocessed stone. This is how the rough black diamond looks (photo). Here both the lunar surface and coal.

Treatment

There are two types of black diamonds: dense and porous. The first species is rarer and better allows it to be cut and polished. The quality of the diamond is much higher. In addition, some of the stones do not have a black color. It can be uneven, from dark brown to dark gray. But all of them are classified as black diamonds.

Some gemologists do not consider black diamonds to be diamonds. However, the trade was firmly entrenched in the name "black diamond", and everyone was 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 shades or spots. But a black diamond, for all its rarity and attractiveness, has such brilliance and brilliance as ordinary transparent diamonds. He does not disperse the light. But the graphite, which is part of its composition, absorbs light and gives the color and shine to the stone.

Only a special cut allows you to get a brilliant shining diamond from a black diamond. But this is very laborious work, because in not very experienced hands the black diamond begins to crumble. So cutting and subsequent polishing greatly affect its appearance. Only the faces of a diamond reflect light, not all of it. It's the faces that will shine and sparkle. The consistency and clarity of the application of faces is very important.

Only the correct treatment will make a fiery glow of a black diamond. The stone "will play".

Cost

The price of black diamonds is lower than normal, transparent, and all because of transparent diamonds of poor quality, blacks are obtained in quite a large amount. A well-ground round black diamond costs $ 1400-1700. At the same time, he does not have any defects. Black diamond - a very ancient stone, but only relatively recently, in the twentieth century, it was appreciated in the jewelry market. Therefore, prices for black artificial diamonds are much lower. Weight, color and cut - these are the indicators of quality. Of these, the price is formed. The price of one carat can start from 1000 dollars and reach up to one and a half thousand. Of course, to buy an elite stone is not cheap, but it became available not only to blood people. A wide range of products will allow you to choose an ornament for the soul and people of average prosperity.

This stone has become fashionable. Marketing companies work by "spinning" a black diamond, and the prices for it are gradually growing. It depends on the suppliers, their shares and market demand.

Evaluation of the quality of artificial black diamond

It is necessary to examine all faces and make sure that they are free of chips, pores and scratches.

In addition to the certificate, quality assurance can be the laser engraving certificate number inside the stone.

In jewelry

The black diamond dazzles with its beauty, especially in combination with white diamonds. Black, satin shine stone is good and by itself. But in the frame of sparkling diamonds jewelry produces a stunning impression. It is no accident that they acquire creative natures, as well as business, discreet men. They are magnificent in the frame of pink and especially white gold, the brilliance of which they emphasize. But they are also good in silver. Of these, earrings, rings, bracelets are made. Any woman can choose what will emphasize her attractiveness. It can be modest accessories that unobtrusively place accents, but a bright and bright thing is possible from which it will be impossible to look away.

Ring with black diamond

Like none of the stones, a black diamond suits men. The ring with a black diamond looks bravely and noble on the man's hand and fits perfectly with the evening costumes.

The image of a man becomes strict and luxurious at the same time. Aristocratism is revealed, as well as the fact that its owner has a pronounced personality.

A woman of any age, a ring with a black diamond will emphasize her exquisite taste and style, add a subtle femininity, fragility and insecurity, grace.

The flickering of the cosmos on the finger - what can be more poetic? To date, it has become customary to make engagement rings with black diamonds. Usually in the center is located one large black diamond, which is surrounded by smaller transparent diamonds. Any jewelry with a black diamond - a beautiful accessory that you can dream about, emphasize the style and taste of its owner. Any design of the ring will attract respectful attention, since it looks organic with any style. Evening attire, strict business suit, cocktail dress, made in the style of "black & white" - everything is in perfect harmony with the ring. Business meeting or work in the office - the ring is appropriate everywhere.

Refined Diamonds

Since the popularity of natural black diamonds is growing, but natural is not enough, then the market receives enriched diamonds. 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 being done, again in Israel and in Belgium. In Israel, there are technologies that improve the purity of ordinary diamond. Those inclusions that are found in the stones become invisible. "By eye" they are almost invisible. Only a specialist (jeweler or gemologist) will determine which stone is before him. And the visible result is a pure sparkling stone. At the same time, the cost of artificial diamonds is more than half as compared with natural diamonds. Due to the elimination of small voids by the laser method, light passes through the entire diamond from the bottom up. As a result, the stone "plays" and shines magnificently.

Improved color of a diamond

To get a perfectly black diamond, use diamonds with defects, which then hide the black color. Therefore, their cost can fluctuate very sharply: from $ 100 to several thousand for one carat. Too much depends not only on the quality of the laser treated stone, but also on cutting and polishing. In the certificate and the guarantee of this stone, it is always indicated how the stone is processed, but its price is never fixed.

Precious stones give rise to both desires and lusts, and carry frenzy, lead to death and crown love stories.
