Nanostallic is a synthetic mineral that has more or less pronounced transparency and a wide range of shades. It is created by crystallizing the most ordinary glass, prepared with the addition of the necessary chemicals. The result is a material with very high performance characteristics. For those who are interested in Nanoall, as well as those who want to find out what kind of stone it is, the article below will provide comprehensive answers.
What is Nanoall
The material in question is classified as glass-crystalline. Today it is used in a wide variety of industries. By the way, only one company in the whole world is engaged in the production of nanometal, and it is Russian. It was the RusGems employees who were able to bring the production technology to perfection, which made it possible to obtain very high-quality and practical material.
The basis of synthetic stone is the oxides SiO₂, as well as Al₂O₃. Then, other ingredients are added to this pair, which is part of literally any precious mineral, to ensure that the final product meets the specified parameters. What is important is that the synthesized stone always has ideal optical characteristics, which natural minerals often cannot boast of.
Features of pendants with nanocrystals
Nanocrystals are a collective name for analogues of precious stones made in laboratory conditions. Such stones are divided into two groups .
- Replicating the original breed in composition . These are artificially created corundums, diamonds and emeralds, consisting of the same chemical elements as natural minerals.
- Stones that have no natural analogues . The most famous representative of this category today is cubic zirconium dioxide, also known as cubic zirconia.
Nanocrystals are produced using different methods (Verneuil, Czochralski, etc.). Their color palette is no less rich than that of real precious stones. For a very modest amount you can buy jewelry with an insert of sapphire, turquoise, ruby or emerald color. In this case, the shade will be even, natural and pleasant, and the shine will be strong and glassy. The latter is facilitated by the high refractive index characteristic of nanocrystals.
Synthetic stones have a hardness in the range of 7-9 points, which makes them resistant to mechanical damage
When properly stored, nanocrystal pendants can look like new for decades. After all, it is most often framed with silver - a noble metal that is indifferent to oxidation.
How Nanoall was created
Ceramic glass has come a long way before becoming a material for jewelry. The first heat-resistant and super-strong glass was obtained by the famous scientist R. Reaumur back in 1739. At that time, he was already a member of the St. Petersburg and Paris Academies, but, nevertheless, his invention did not initially attract much attention. The problem was that the new glass was opaque and more like ceramic.
As a result, the development was forgotten for almost two centuries, until the need to create a new material arose among the Americans. Really strong crystallized glass was soon produced all over the world. In each country it received its own name, but it was called glass-ceramic by the Soviet physicist I. Kitaigorodsky.
Physical properties
Despite the fact that glass-ceramic is very similar to glass, it has properties that differ from it. Its formula is similar to rock crystal. Quartz glass is obtained from it.
Let's look at the available properties:
- The first property is hardness . It is measured using the Mohs scale and this value is 8 points. This parameter is 1 point less than that of corundum.
- The second property is porosity. And this value is zero.
- The next property is density. Sitall density 2400-2950 kg/m3. Therefore, this material has very good thermal conductivity.
- Its structure is fine-grained , therefore it has excellent electrical insulating properties.
- The melting point is 1030°C , but it can be higher. It depends on the type of stone, but it does not go below this value. Heat resistance is increased by adding lithium and aluminum to the glass ceramic composition.
- The stone is also resistant to chemical treatment.
- also very transparent , which is undoubtedly a positive property. Moreover, it depends on the size of the crystals.
All these properties are due to the components used for production. The basis is the charge, that is, a certain mixture of materials.
It contains one or more nucleating substances. And they were called nucleators. They increase the number of central elements for crystallization. As a result, there are many such formations in 1 mm3.
Receiving process:
- First you need to melt the charge. This process is divided into 2 stages. First, crystallization centers are formed, then the temperature is brought to such a value that the growth of aggregates occurs.
- The next step is to develop mass. This process involves casting objects. Casting products consists of using certain forms.
- At the last stage, the mass is cooled.
Jewelry glass ceramics
Nanoall began to be used in jewelry only in the 21st century. Initially, that is, in the 70s of the last century, the material was used for inexpensive but strong facing tiles. Since the composition included waste from the metallurgical industry, it was not particularly beautiful, but since it was intended for industrial enterprises, this was not required. In addition to gray-black products, in the early 80s they mastered the production of beige varieties.
Only in the current century was it possible to give glass ceramic the necessary transparency and other acceptable decorative properties, which ensured the popularity of synthetic crystals. Now they decorate a variety of products:
• necklace; • brooches; • rings; • bracelets; • hairpins; • pendants; • earrings.
How to choose a pendant with nanocrystals
The pendant is chosen taking into account where and how often it will be worn. Exquisite pendants for evening style are selected according to one criteria, and jewelry for every day - according to others. After all, the compatibility with clothing of these options is different. But there are also things to consider when choosing any pendant. We are talking about appearance features:
- eye and hair color;
- skin tone;
- neck length and thickness;
- breast size;
- complexion;
- height;
- age.
In order for the pendant to maximally emphasize and reveal the advantages of appearance, it is advisable to take into account all the listed criteria. And, naturally, when buying a piece of jewelry, you need to make sure of its quality.
In order not to run into deception and low-quality goods, it is better to make purchases in large jewelry stores. And even there it wouldn’t be superfluous to inspect the product and check the fittings
If you like to buy from online stores, give preference to sites with an impeccable reputation.
Existing colors
The first sitalls, as noted above, could not boast of either beauty or richness of shades. The oxides of some metals used initially gave a brown-green color. Only later was it possible to obtain first a milk sample, and then others. Today it is not difficult to find copies:
• purple; • blue; • green; • pink; • dark red; • brown; • purple, etc.

Volume shoulders. The 80s continue to rule the show, only slightly giving way to the 70s and 90s – coats, denim jackets and dresses with geometric, voluminous shoulders continue to appear on the catwalks. This masculine cut looks great in contrast with a tight skirt or leggings and a fragile figure, and also hides a couple of centimeters from the hips and accentuates the waist if it is a shortened model. One caveat - shoulder pads are not suitable for those girls whose “native” shoulders are already wider than their hips.

Application of stone
Sitall is actively used for making jewelry. Brooches, earrings, bracelets, and rings are made from it. The mineral is characterized by rich color and shine. It goes well with precious metals - silver, gold, platinum.
Artificial stone is also used in the following areas:
- Mechanical engineering - in this case, the properties of stones can be adjusted by using the required components in the composition. For example, adding perlite or dolomite to crystals turns them into reliable electrical insulators.
- Optics - raw materials have a high degree of transparency. Therefore, it is used for the manufacture of lenses, mirrors and other optical products.
- Oil and gas pipes made of glass-ceramic are characterized by high strength.
- Electronics - crystals are used as insulation for microcircuits.
- Aviation - the material is used to create rocket fairings.
- Medicine – in dental practice, crystals are used as a filling material.
Note! Glassware is used to make dishes and other containers. They are highly durable and suitable even for microwaves.
Sitall is a synthetic mineral that has unique properties. It is often used in the jewelry industry and other areas of life.
Synthesis
The traditional method involves molecular precursors, which may include typical metal salts and an anion source. Most semiconductor nanomaterials contain chalcogenides (SS−, SeS−, TeS−) and pninides (P3−, As3−, Sb3−). Sources of these elements are silylated derivatives such as bis(trimethylsilyl) sulfide (S(SiMe3)2 and tris(trimethylsilyl)phosphine (P(SiMe3)3).[7]
Nanoscale tertiary phosphine-stabilized Ag-S cluster prepared from molecular precursors. Color Code: Gray = Ag, Purple = P, Orange = S.[8]
Some procedures use surfactants to solubilize growing nanocrystals.[9] In some cases, nanocrystals can exchange their elements with reagents through atomic diffusion.[9]
Why are artificial stones created?
This is due to one problem that worries absolutely all producers - the cost of natural precious (and semi-precious) minerals is constantly increasing, which is due to increasing inflation and a reduction in their production. And the second point is that buyers are not ready to part with their money and purchase expensive jewelry.

Because of this trend, jewelry manufacturing enterprises have to purchase more budget-friendly options, which are substitutes for natural gems.
Stones created by jewelers have received many different names - for example, they are called artificial, recreated, pressed, hydrothermal, grown, and so on. The essence of the name, of course, does not change at all - the source material of such minerals is created by people.
When talking about artificial stones, you should not focus on the name of the material, because much more important are the consumer properties of jewelry stones, as well as the degree of similarity of the fake to a natural stone and, of course, the cost.
History of the creation of hydrothermal stones
History of the creation of hydrothermal stones:
- Until the 18th century. During these times, many scientists attempted to make jewelry from various minerals and glass.
- 1885-1891. French scientist Auguste Verneuil creates the first synthetic ruby. Later they became known as Geneva rubies. At first he worked with the chemist Edmond Fremy, but after a while he himself developed a method for creating hydrothermal stones using a burner. In 1902 he published the results of his work. The laboratory where these stones were created soon turned into a special production facility. It produced several tons of synthetic rubies. The price of a ruby can be found here.
- 1960-1980. During this period in Russia there was a large surge in popularity for synthetic stones. Jewelry made from 583 gold was often purchased. Sapphires with bright red and bright blue colors. Corundum products have appeared that change color.
