How to distinguish an artificial stone from a real one?

Granite is a rock of igneous origin, which contains feldspars, quartz and biotite. Natural granite has become widespread due to its attractive appearance and excellent performance properties. However, natural stone is a rather expensive material, so there are many of its artificial analogues on the market, which are significantly inferior to natural rock in terms of durability and a number of other properties. Moreover, unscrupulous sellers often try to pass off fake granite as real granite.

Features of natural granite

In order not to fall into the trap of scammers and not to purchase an artificial analogue instead of a real stone, you need to know the features of granite.

What does granite look like?

This material has a granular structure with a rich palette of shades. The color of granite can vary from gray and black to pink and terracotta. One of the most valuable types of this stone is considered to be Van Gogh granite, mined in the Italian Alps. In this mineral, the mint green and turquoise blue background is stitched with orange veins. Depending on the grain size, granite can be fine-, medium- and coarse-grained. In veined rocks, the pattern appears layered, as it is formed by hundreds and thousands of large and small veins. Among connoisseurs, the most valued stones are those that have an even pattern – this is a sign of high quality granite. Such vein rocks include “Gabbro” granite from the Bukinskoye deposit. Natural granite cannot be scratched by accident – it is so hard that only diamond bits are used to process it. Granite products are known for their durability. Even after a century, countertops and cladding retain their aesthetic and performance properties. Not a single product made of artificial stone can boast of such an impeccable service life.

Comparison of natural and artificial granite: how to distinguish

How to determine whether granite is real or not? One of the easiest ways is to touch it with your hand. Natural stone always has a low temperature. If you press your palm against a granite product, you can see how it gradually warms up from the heat of the human body. Unlike natural stone, analogues will quickly become warm. The second way to distinguish an artificial stone from a real one is to look at its color and structure. What does granite stone look like? It has a grainy structure, a unique pattern without repetition, and a matte surface tone even after polishing. Synthetic stone can be recognized by its repeating lines and patterns – it is almost impossible to find them in real rock. Each pattern will be unique and inimitable. The exception is rare types of granite, which are very, very expensive. Real granite will not appear glossy, while its artificial counterpart in most cases boasts an impeccable, smooth surface with a glossy sheen. It is also worth paying attention to the inclusions of grains. Natural stone contains various minerals, the grains of which are randomly distributed in the structure of the rock. In artificial stones such chaos is not observed. The third way to distinguish natural granite. In the production of polymer granite, granite chips are used, which are combined into a single whole using a polymer composition. Upon careful examination of the stone, you can see that the “grains” of such granite are not soldered together, but are bonded with a polymer. When purchasing granite curbstones, the finish can be distinguished by the presence or absence of an uneven break near one of the corners. When cutting granite stone for curbs, the cut is not made completely. That is, a small fragment remains that holds the pieces of stone together. When installing curb stones, the joint is broken, resulting in an uneven edge. Artificial granite has smooth edges and corners. Unexpectedly, granite has transparency. Its presence is explained by the fact that granite contains quartz and mica (biotite). These minerals are characterized by transparency, so in places where they accumulate in the structure of the stone, granite will also exhibit this feature. Natural stone is considered a sign of special status and wealth, so it cannot be cheap. The desire to save money can result in the fact that in a couple of months a luxurious countertop will become covered with scratches and lose its attractive appearance – after all, it was actually made not from natural granite, but from artificial one. To avoid getting into trouble, granite must be purchased from companies with an impeccable reputation that can provide all the necessary accompanying documents and confirm the natural origin of the stone.

At the same time, at present, when the market is simply replete with jewelry with colorful stones, the issue of identifying and distinguishing a real treasure from a possible fake is of particular relevance. In this topic we will discuss how to check your jewelry for authenticity at home.

The main signs of natural stone

What makes a mineral precious? Of course, its beauty, rarity (uniqueness), wear resistance (hardness, strength). In the fashion world, it is believed that a talented model does not have to be perfectly beautiful, quite the opposite: her beauty lies in her uniqueness – she is original and not like others. The situation is exactly the same with precious stones: defect-free, impeccably pure minerals are extremely rare in nature . If such samples are found, their cost reaches a very high level. Laboratory stones, in turn, have better visual characteristics and are several times cheaper. There are 3 types of fake jewelry stones: synthetic (grown in laboratory) fake (less valuable ornamental stones, similar to expensive jewelry stones) and imitations made of glass and plastic. In nature, the formation of a precious stone takes several tens or even hundreds of thousands of years: it is not surprising that natural “traces” (various inclusions, dents, microcracks) are a completely natural phenomenon. Under special laboratory conditions, the stone can grow within a period of several hours to a maximum of several months. Synthetic stones appear flawless, but the laboratory cannot recreate a process that completely replicates the natural one. Based on this, artificially grown stone does not have the magical and healing properties inherent only in natural stones . Therefore, the captivatingly bright Linda crystal cannot become your amulet and talisman. What do professional gemologists study to determine the origin of a stone? First of all, these are internal inclusion , zoning (color distribution), growth microstructures , for observation of which a magnifying glass or microscope is used, as well as a polariscope, dichroscope and ultraviolet lamps. There is one simple rule that is typical for most stones – natural minerals (except amber) are always cold . Fakes made of glass and plastic are warmer to the touch. To understand whether the stone in front of you is genuine, you can hold it with tweezers and bring the stone to your cheek – it should be cold. Another feature – laboratory stones are always brighter than natural ones , they may even have an acidic tint. Natural minerals have calmer, “not flashy” tones, and most gems are characterized by the effect of dichroism – the property of changing color depending on the direction of light.

Methods for identifying popular minerals

Below we will provide simple recommendations that will help you check the authenticity of the most popular gems and, although not 100%, will still protect you from buying an obvious fake. Ways to check the real one diamond plenty. The diamond can be rubbed with sandpaper – it should not leave marks in the form of scratches. If you look through a diamond into the light, only a luminous point should be visible in the crystal. And when immersed in water, a real diamond will shine brightly. It is also known that diamond leaves scratches on glass and on the surface of other stones due to the fact that it has the highest degree of hardness. Emeralds They fake it quite professionally. At the same time, if you look at the stone through a magnifying glass, you should see a characteristic pattern in its structure – parallel growth lines, but not spiral patterns. In addition, emerald almost always has defects and cracks. And remember: natural emerald should be cold. Natural ruby It is extremely rare to be clean, large and brightly colored. There are several methods for diagnosing ruby:

  • a real ruby ​​is not without microscopic defects and inclusions, even if at first glance it seems perfectly transparent;
  • from one viewing angle, a natural ruby ​​will be dark red, and if you look at it from the other side, the shade will be paler;
  • a natural ruby ​​immersed in a glass of milk will turn it pinkish;
  • under ultraviolet light, the fake stone will appear orange;
  • If you place a ruby ​​on the eyelid, it will remain cold for some time. A synthetic substitute or glass instantly changes the temperature to a warmer one.

Distinguish the real one sapphire from multiple “twins” based on external signs is not easy, since methods for its synthesis are constantly being improved. The sapphire offered to you is presumably natural if:

  • the effect of “milk fog” can be seen on the stone, i.e. white highlights, especially pronounced in Kashmir sapphire;
  • characterized by zonal (uneven) coloring;
  • there is a grayish or pearlescent sheen;
  • there are internal defects;
  • the stone has high hardness (9 on the Mohs scale) and is capable of scratching any stone except diamond.

Easy to spot with the naked eye star sapphires and rubies , in which the main feature is the optical effect: a multi-pointed star, whose presence on the surface of the stone is due to the presence of rutile, is characterized by mobility, i.e. it changes position depending on the viewing angle. This effect has not yet been replicated in laboratory conditions.

Garnet refers to minerals that have a magnetic attraction force. There is a simple method for testing a pomegranate; for this you will need: a magnet, metal scales and a cork. We put the cork on the scales, put a stone on it (to separate it from the metal pan of the scales). When the scales are balanced, we bring the magnet to the stone. If the garnet is natural, the balance will be disrupted – the scale arrow will begin to fluctuate. If you look through the crystals of a real garnet into the light, you will notice small defects and uneven coloring. In jewelry, natural garnet rarely exceeds the size of a garnet seed.

The main feature of natural amethyst are natural defects and inclusions visible through a 10x magnifying glass. Natural amethyst does not conduct heat well, and if you apply it to your cheek, it will remain cool for a long time. And in water, a real amethyst turns pale at the edges, as if its color is washed away by moisture.

Beloved by many, sparkling mineral topaz can be determined by touch by its characteristic “slipperiness”: when you touch it with your skin, it should be smooth and cool. Although topaz is a transparent mineral, in nature it is rarely perfectly clear, so when examining the stone through a magnifying glass, you will notice small inclusions. If you rub natural topaz with a woolen cloth, it will accumulate electricity and will attract small particles (a piece of napkin, hairs and other light debris). However, there are also high-quality fakes of topaz that even imitate the physical properties of the mineral. In this case, the authenticity of the stone can only be determined in a gemological laboratory.

Natural color citrine not as acid-bright as substitutes may be. When viewed from different angles, natural citrine changes shade from golden lemon to sunny yellow. Imitations do not have such properties.
