Hydrothermal emerald: description, characteristics and properties

Today's technologies are so developed that virtually unlimited possibilities are revealed to a person. Nature is generous, but its reserves are not unlimited. The beauty and properties of natural stones are sometimes amazing, but their cost is not affordable for every connoisseur of beauty. Therefore, grown in the laboratory, stones are in demand and widely popular.

Hydrothermal emerald - a vivid example of this. Unfortunately, not all are aware of the characteristics and characteristics of these stones, and prejudices based on delusions are abundant. Because of this, many consider such gems as nothing more than a cheap counterfeit, unworthy of attention. In fact, the emeralds grown in laboratories are quite worthy of our attention.

Hydrothermal emerald: what is it and why is it needed?

It would seem, for what it is necessary to grow stones in laboratories, if there are many deposits around the world? But there are several reasons for this phenomenon. The main one is related to the peculiarities of natural stone - in nature, emeralds of large size are extremely rare. Not surprisingly, the prices of large gems fly to the sky. Even crystals of 5 carats can cost more than diamonds of the same size - of course, provided good color and transparency. But in the laboratory you can grow almost any crystal.

Even small stones the size of a crystal of sugar fall into the skilful hands of jewelers. They are processed, polished or grinded, decorated with jewelry, placed around the main stones. But very small dust is unsuitable for business. She even gets to the laboratory, where she turns into crystals of hydrothermal emerald. Often jewelers use natural stones of poor quality. They get rid of foreign inclusions and impurities, they are crushed, after which they are quite suitable for growing beautiful and high-quality crystals. This is a wonderful example of the rational use of resources, careful attitude to the gifts given to nature by wealth - after all, it is something that could simply be thrown away. But instead of this, even from an unnecessary, seemingly dusty person, he learned to create the beautiful.

History of artificial cultivation of emeralds

Technology is relatively new, it is a little over a century. Emerald synthetic hydrothermal has its history since 1888. The scientists Perre and Otfel were not the first to try to grow this stone in the laboratory, but it was their successful experiment that laid the foundation for a new technology that is used today.

In 1911 scientists from Germany undertook the task, which managed to make significant progress. But the government of the country imposed a ban on the publication of any research results, all developments were kept secret until 1960. It is worth noting that the atmosphere of strict secrecy, enveloping the achievements of German minerologists, gave the world an opportunity to think about the excellent results of their labors. In fact, the appearance of the hydrothermal stones produced in Germany, to put it mildly, left much to be desired. They looked little like the original.

Later many other scientists were engaged in research and practical experiments. Today we can safely say that the technology for producing hydrothermal emeralds has been perfected.

Process Features

Probably everyone who studied physics at school can easily guess by the name that the technology is based on processes related to water and temperature. This is really so. The following is happening.

Powder obtained from the cutting of natural stones, as well as from emeralds of poor quality, is immersed in an autoclave. In this vessel, it is affected by chemical components and high temperature. The powder dissolves in the strongest solvent - in water.

Then the vessel is placed in a special zone with a low temperature, where the crystallization process takes place. Emeralds settle on a substrate-primer. Understanding what the hydrothermal emerald means, we can talk about how much it can look like the original. After all, the process of the natural formation of this gem takes place according to the same scheme, but takes millions of years. Laboratory is the same stone is formed only about a month.

Extensive features: shape, size, quality

Scientists are able to grow a hydrothermal emerald with almost any characteristics.

For example, in nature, there are almost never emeralds with absolute transparency. Almost always they contain inclusions. Absence of impregnations in the crystal, especially in the large one, is one of the main signs of forgery. That is, it is not even a hydrothermal emerald, but a piece of glass, plastic or other synthetic material that has nothing to do with the emerald. But grown in laboratory crystals have small impregnations, as well as natural stones. This process is difficult to control, it happens by itself, because everything follows the same pattern as in natural deposits.

As for the form, the possibilities of scientists are quite wide. They can get almost any stone, which when cut will turn into a beautiful specimen. In addition, it is possible to grow pretty large stones on the laboratory, but it's worth mentioning that this happens rarely. The large-sized emerald is alarming, suggesting a fake. Therefore, even hydrothermal gems are usually small.

Properties of GT emeralds

Cultivated stones have the same chemical formula as natural stones. They have a high density, they are not easy to process. Hydrothermal emerald visually almost does not differ from natural emerald, but nevertheless has some features:

  • Emeralds of GT always have high transparency;
  • Contain inclusions in the form of tubes;
  • Can have scattered brownish patches;
  • Sometimes include air bubbles;
  • Can be a blue-green color.

Of course, these signs are very arbitrary. In many respects, the properties of stone depend on the features of technology and raw materials.

Are there similarities?

Hydrothermal emerald is similar to natural stone quite strongly. So much so that sometimes even a professional jeweler finds it difficult to determine the origin of the gem.

But with all the obvious similar qualities, there is still a difference. This is something that can not be explained and described with the help of formulas, as if it is a matter of the power that has been absorbed for millions of years. The natural emerald plays with faces, pouring in the sun's rays, hydrothermal crystals can not make them a competition at all.

Use in jewelry art

This stone is often processed and enclosed in a decent frame, even the most solid jewelry houses. The use of a hydrothermal emerald is not at all a mauveton, of course, provided an adequate price and no falsifications.

When creating jewelery, jewelers follow certain rules. For emeralds of GT, rational additions are needed. For example, earrings with a hydrothermal emerald are decorated with cubic zirconia, crystals of rock crystal, other hydrothermal gems. Of metals, the usual yellow gold and silver are most often used.

Price list

Another feature that distinguishes a hydrothermal emerald is the price. Of course, it is much lower than a stone of the same size, grown by nature.

On average, the price of a cut stone is 30-50 dollars per carat. In some cases, the cost may be higher - for example, stones with impeccable cleanliness and fine faceting.

Precautions for purchase

If you are looking for a ring with a hydrothermal emerald, knowing in advance the characteristics of the origin of the stone, then the risks of running into a fake are not great. Remember that this stone is much stronger than glass, it can not be scratched so easily. In addition, the emerald GT has a deep color, often with a shade of blue.

Another thing is if an unconscientious jeweler gives out an artificially grown stone for natural. In this case, the risk of losing money is huge. Not every jeweler can easily distinguish a fake. Therefore, when buying jewelry with natural emeralds, you should not trust casual sellers, too low prices, jewelry without documents. Do not hesitate to ask the seller for quality certificates, examination results.

Focus not only on the appearance of products, but also on your own feelings. Experts say that if your stone, then you will immediately feel it.
