Artificial diamonds: what they look like they get and where they are used?

Diamonds are distinguished by the unique density of the structure that allows the stone to withstand heavy loads and high temperatures. This property is applied in space experiments and development, in the production of medical devices and exact hours, nuclear industry. After the cut, a beautiful mineral turns into a diamond, which is highly valued by jewelers. Modern technologies allow you to create it in artificial conditions, reducing the price without loss of quality.


For active use on an industrial scale, artificial diamonds began to be issued since 1993. Their quality was so high that jewelers needed special tests to determine the authenticity of stones. For a regular consumer, the difference was not obvious at all, so many companies began to apply crystals to create luxurious jewelry.

In modern laboratories, there are several types of this synthetic stone: CERUSTSITS, PLABULITES, RhINS, ferroelectrics, Moissanites. The most beautiful and clean is the cubic of zirconium dioxide, which is called “Fianit”. It is used in many areas of industry, complements the collections of fashion houses Thomas Sabo and Pandora.

The main features of artificially grown diamonds:

  • Low cost compared to natural stones (the price is less than 10-15 times)+
  • Easy cut+
  • Lack of hidden defects that affect the hardness (air bubbles, cracks)+
  • Full imitation of a real diamond after cut.

Among the lovers of beautiful stones also split opinions on the properties of non-human stone. Some of them believe that only a real diamond is able to drive off evil spirits, protect its owner from damage and evil eye, helps him in commercial affairs.

Holders of artificial diamonds argue that their decorations will no less effectively emit positive energy and bring good luck.

Artificially created stones in recent years are developing well-known brands of Diamond Foundry, Helzberg S Diamond Shops and Lifegem. This business in the United States is considered the most profitable and promising, as environmental harm is minimal. In addition, many geological experiments prove that the period of diamond formation in nature is over. Therefore, the development of new deposits will soon go back to the past.


Real diamonds are popular for several centuries. Expensive diamonds decorated royal clothes and crowns were inherited and entered the golden stock of the treasury of many countries. Even today, the fared minerals are the best investment that only increases in the price every year.

Therefore, the first developments and attempts to create a synthetic stone began at the end of the XIX century.

The first artificial diamond was obtained in 1950 by Swedish scientists in the laboratory of ASEA. After research, their experience repeated the American company General Electric in 1956, improving technology. For several decades, new methods and development appeared, which allowed to change the shade, shape and dimensions of the synthetic mineral. In 1967, a patent for the cultivation of jewelry stones was obtained.

The history of their receipt in the Soviet Union begins with the first stone, which was synthesized at the Institute of Physics and High Pressures in the late 50s of the last century. But the active work in this direction is conducting a scientist. AND. Leipunk, who has released many scientific papers and settlements back in 1946.

His work in the field of chemistry was used as a basis for new methods, they practically became the basis for the modern industrial production of artificial diamonds.

This breakthrough happened in the early 60s of the last century, when young scientists of the Moscow Laboratory of High Pressure created a special press. With it, it was possible to establish a large-scale release of superproof stones: the volume reached a thousand carat per day. All manufactured technical diamonds were used for the needs of rocket launch and mechanical engineering, went to export, bringing billionaire profits.

In recent years, in Russia, new technologies are developed by private jewelry houses and scientific laboratories.

They attract foreign experts from South Africa, USA and Europe, trying to reduce the methodology.

How do synthetic diamonds?

Artificial diamonds grown in laboratories of leading chemical companies, it is difficult to distinguish from the real stone on transparency and brightness brightness. But all the well-known methods require large capital investments, are laborious.

Therefore, the main task of scientists is to find the perfect balance between quality and cost of production.

Methodology NRT

NRT or HIGH PRESSURE, HIGH Temperature is the most common technology. The basis of the synthetic phyanitis, scientists laid real stones of 0.5 mm quantity. In a special chamber, on the principle of work resembling autoclave, a combination of temperature is created at least 1400 ° C and a pressure of 55,000 atmospheres. On a natural base, different chemical compounds are superimposed, films of graphite.

After 10 days of such an impact, strong sigma communications arise, the compounds around the base are formed into a solid and transparent stone.

Such a technology as much as possible natural conditions for the appearance of the mineral, so the quality is always at the height, defects are practically excluded.

CVD production or film synthesis

This technology is one of the first in the cultivation of artificial minerals. It is widely used, if necessary, creating a particularly durable and acute diamond coating, creating high-quality diamonds. All components and diamond substrate are laid in special cameras that create a vacuum. After filling with methane, the impact of microwave rays begins, well known for the operation of the microwave oven. At high temperatures, carbon chemical connections start melted and connect with the basis.

CVD technology gives high quality diamonds that are not inferior by properties. They are based on the technology of replacing wear-resistant boards of computers, dielectrics and ultrathin scalpels in ophthalmology.

Scientists hope that in the near future for 1 carat of synthetic stones obtained using this technology, it will be possible to reduce the price of up to 5-8 dollars.

Technique of explosive synthesis

One of the latest developments is a way of explosive synthesis. It is based on a combination of sharp heating of the chemical mixture using an explosion and subsequent freezing of the resulting mineral. As a result, a synthetic diamond with natural properties produced from crystalline carbon is obtained. But the high cost causes chemists to look for new variants of the synthesis of stone mass.

Scope of application

Among all diamonds, synthetic stones occupy only 10% of the market. Cheap fianitic crystals are used for the manufacture of female jewelry. Famous fashion houses adorn them evening dressing, handbags and shoes, use in an exclusive decor.

Progressive youth increasingly chooses them for safety and environmental friendliness.

More than 90% of artificial diamonds are used in industry. Main directions:

  • High-precision grinding machines, solid material cutting tools+
  • Microelectronics and manufacture of computers+
  • defense industry+
  • robotics+
  • Unique lasers for eye operations+
  • Mechanical engineering+
  • New machines in metallurgy+
  • Rocket Label.

Among the latest achievements – the use of synthetic diamond for the manufacture of artificial lens. Transplant operations showed that the purity and lightness of the cut makes the implant ideal for the patient.

It is distinguished by the right corner of refraction and durability.

Comparison with natural stones

The industry produces a synthetic diamond, so similar to the natural crystal that a number of laboratory tests are required to identify it. Consider the most common differences.

  • All artificially grown diamonds have a special stamp. It reports the name of the company or the laboratory, which produced the product.

  • For inspection, it is better to use a magnifying glass, but a powerful microscope. In workshops, defects are detected using a spectrograph, shone under the rays of ultraviolet.

  • Real diamonds do not react to the electromagnetic field. As a method of verification, this property can be used: the synthetic stone is attracted to a strong magnet.

  • If you need to identify a diamond at home, it is put on white dense paper. With careful consideration, the growth zone becomes noticeable, which occur when the layer of carbon under high pressure occur.

  • Natural stones are created from the smallest single crystals, so they have a homogeneous structure. Unfulfilled products with a detailed examination under the microscope, as if composed of a variety of microscopic crystals.

Diamond Stock Exchanges Use Special Devices Diamond Check and M-Screen.

In just 10-15 seconds, they allow to distinguish the synthetics from natural stone with an accuracy of 95-98%, give maximum information about the quality and structure of the crystal.

      Growing artificial diamonds – promising industry. The active development of robotics and nanotechnology requires more and more stones for the production of lasers, heavy-duty coverage. After processing, a synthetic diamond in 1 carat is estimated at $ 800-900 compared with a natural crystal at $ 4,000. This makes it possible to reduce the cost of many processes, operations in ophthalmology and microsurgery, opens up new opportunities for science.

      On the production of synthetic diamonds is told in the following video.
