Today, specialists in jewelry are much more complicated than their predecessors. If a few decades ago a genuine gem could easily be distinguished from fake even visually, then in the world of modern technology and progress it is almost impossible to do this by eye.
In addition to the well -known glass hacks, imitators of expensive stones from cheaper minerals, a new product has appeared on the jewelry market today - a stone grown in laboratory conditions. Such a creation of human hands visually looks no worse than a mineral created by nature for many decades, but it costs many times cheaper. How to distinguish a genuine natural stone from a fake or unnatural stone? What precious minerals do exist?
What stones, gems and minerals belong to precious noble stones: classification of precious stones
- It will not be easy for a beginner to understand the complex classifications of precious stones. The fact is that today there are quite a lot of them: Sobolevsky, Klyuga, Kyivlenko, Gurich, Bauer-Ferman, etc.
- In order not to stop specifically on each of the classifications, we will try to compose one, generalizing, excluding facing stones from it:
- The first category of stones is precious stones (the most expensive, valuable stones). This category of minerals includes diamond (diamond), ruby, emerald, sapphire, alexandrite, etc.
- The second category of stones is semiprecious stones (more common, but no less valuable). A similar category of minerals consists of: amethyst, aquamarine, almadine, apatite, grenade, mountain crystal, opal, quartz, topaz, turmalin, zircon, chrysolite, etc.
- The third category is jewelry and sub-stones. These include: agate, turquoise, amber, cat's eye, lunar stone, azette, malachite, jasper, tiger eye.
- Some classifications group stones in similar categories, however, at the same time, they also divide the minerals into classes. The class indicates the fortress of the stone, its high cost and beauty.
Black precious stones: name, description, photo
In nature, there are so many minerals released by their black color. Some of them are so rare that it is almost impossible to find any information about them. In many cases, the name “black” stone can be considered relative, since in fact the mineral has a lighter or non -plain color. Here are the most encountered in jewelry Black Stones:
Gems
Black diamond or carbonado
Black diamond is the greatest rarity and value in jewelry. However, it is worth noting that it does not reach jewelry, since its cutting and processing are very difficult - it can only be performed with the help of the same stone. In jewelry annals, only a handful of such stones is listed, the most expensive of which was estimated at 1.7 million dollars. The other two became famous under the names “Black Star of Africa” and “Corloff Noir”.
Black sapphire
Real black sapphire does not exist in nature. Almost all black sapphires are the work of scientists. They are obtained by processing blue sapphires. The same few black sapphires that have natural origin are actually difficult to call black, since their color is closer to the color of the sky at night. The most famous black sapphire is considered to be the “black star of Queensland” worth $ 100 million.
Black Pearl
A similar type of pearl is also difficult to consider truly black, since its darkness is softened by the pearl of the pearl. However, the cost of such a wonders to this day remains quite high. The rarest specimens of black pearls are collected on Tahiti in the corresponding museum.
Black Opal
The specified type of opal is considered one of the most expensive and valuable breeds. Most often, this mineral is found in deposits located in the least developed countries of the world, which determines numerous human losses during its extraction.
Black spinel
Black spinel is one of the most inexpensive types of precious stones of black color. Its cheapness is easily explained by the fragility of the stone and the complexity of its processing. Most often, spinel is used in needlework or jewelry in the form of cabochons.
Semiprecious stones
Black quartz or Morion is the only representative of black -led stones of black color. This mineral today is most often used in jewelry. Outwardly, it has an opaque or barely transparent surface.
Jewelry and exhibition stones
Black agate

White or transparent by nature, minerals are considered the most expensive and valuable stones in jewelry. White precious stones include:
Diamond or diamond
It is the transparent diamond or its already robbed part (diamond) that first come to mind to any person (especially women) when mentioning white precious stones. Indeed, this mineral is considered one of the most popular. Its high cost is easily explained by the few deposits of this mineral in the ground. At the same time, only a small fraction of all the extracted diamonds is suitable for cutting.
Transparent spinel
Unlike its black twin, the white spinel is a fairly expensive stone, which is distinguished by a high fortress. The impeccable purity and the fact of the absence of any impurities in this mineral makes it even more valuable. White spinel is most often used in the jewelry of the Lux class.

Goshenitis is also very similar to the diamond, but its radiance can rather be called more chilling, restrained.
Pearl
White pearls always managed to captivate with their warmth and tenderness of the fair sex. Oddly enough, but in nature, pearls rarely have a round shape (such representatives are very highly appreciated) - more often they are oblong, uneven. The pearl has another feature - the life span. If ordinary minerals will delight the eye with their beauty forever, then the pearl can “go out” at any time. The life expectancy of this mineral does not exceed 300 years.
Ahroite or white turmaline
Such a breed is very rare, since its deposits are located only at one point on the map. In the form of jewelry, ahroite is quite rare. Such pleasure can be ordered in only a few jewelry workshops of the world.

How to distinguish natural stone from a fake, from glass in jewelry?
For a jeweler or high -class appraiser, it will not be difficult to identify the authenticity of the stone using special tools and devices. As for the inexperienced layman, it will be very difficult to distinguish a real stone from a fake for him. In such cases, professionals recommend using the following techniques:
- Natural stone, as a rule, is much stronger than glass or plastic fake. If you spend a sharp object on it, then there should not be a trace on it. At the same time, a scratch may form on a fake. But this method is relevant only when it is necessary to distinguish hacks from a real stone - if in the product instead of a precious stone of the highest level, a natural but less expensive mineral is involved, then there is no point in conducting a similar experiment.
- Natural stones have a cold touch. If you put the stone on the tongue or attach it to the cheek, then it will remain cold for a long time. If glass or plastic is used in the product, the stone will heat up quickly enough.
- Natural stones grown in the bowels of the Earth are rarely large, but artificial minerals created in laboratories can reach more impressive sizes.
- The color of natural stone is rarely very saturated, bright. At the same time, creating hacks of any color and shade is quite simple.
- Do not count on the fact that natural stone will cost a penny - the price per carat of the precious mineral can reach thousands and hundreds of dollars.
- When buying a product with natural stones, you can ask the seller to provide a certificate for the authenticity of the stones.
In fact, all precious minerals have completely different chemical and physical properties. Therefore, the identification of each of them must be approached individually.
