525 standard - Which standard is better in gold, 525 or 585?

Gold products are expensive and exquisite jewelry that best emphasizes the status and position of their owner. True luxury is available only to a few who are able to appreciate its beauty. Time has confirmed the significance and importance of this noble metal in the life of man and humanity as a whole.

It is extremely difficult to overestimate the need for gold, since it is not only a material for jewelry, subsequently used as an accessory, but first of all, it is an established world currency!

375 gold is contraindicated for those who are allergic to nickel

This is the biggest drawback of 375 gold alloy - the nickel in its composition can cause an allergic reaction.

Because the percentage of nickel in this gold alloy is higher (compared to 585 and higher alloys), products made from it are more likely to cause skin irritation and other allergy symptoms.

Jewelry made of 585 gold practically does not cause allergic reactions, and yet people prone to allergies are recommended to test the product first.

Where is it used?

People at all times have been mining the “yellow metal”, finding application for it in various areas of their activities. Thus, the gold alloy in question is in demand in industry and is actively used in medicine. First of all, it is used in places where its characteristics such as strength and elasticity are needed. In medicine, this metal is valued for the fact that it does not cause allergies in patients. Medical instruments are made from it, used in prosthetics, and dental crowns are made.

In jewelry, material with such markings is also used, but rarely. Due to the predominance of copper in some brands, it can be subject to corrosion. It is mainly used to produce low-priced products. Some jewelers use this metal in combination with other types of gold alloys. It allows you to make individual details in jewelry as refined as possible. Before the collapse of the Soviet Union, wedding rings were made from red gold, which were not very diverse, but were practical.

The sufficient density of the gold alloy in question allows it to be used as a coating for inexpensive jewelry, as well as vintage products for expensive cigarette cases, pendants, pins, pens and brooches to give the effect of wealth and luxury.

What to choose: 375 or 585 gold

It is impossible to say for sure which type of gold alloy is better. When choosing, there are many factors to consider, as well as individual preferences. If you want everyday jewelry that you will wear all the time, then it is better to opt for a product made from 375 gold - it is harder and more scratch-resistant. A ring made of 585 gold will wear out faster and become scratched if worn constantly. An additional advantage is the lower price of products made from 375 gold alloy.
As noted above, diamond jewelry is typically made from at least 585 gold alloy.
If you are allergic to nickel, it is best to avoid jewelry made from 375 gold and opt for jewelry made from 585 gold or a higher purity alloy.
As for appearance, it’s up to you to decide which of these types of gold looks more attractive, and whether it’s worth paying extra for a higher standard.

56 hallmark gold is a hallmark from the times of Tsarist Russia, which was placed on individual gold jewelry and decorative items. Today, such engraving is found quite rarely and mainly on antique objects.

Let's figure out what hallmark 56 gold in Tsarist Russia is and what modern gold it corresponds to. In addition, information will be provided regarding what the 5s5 engraving is, which is occasionally found on products. It will be useful for many to become familiar with the metric system introduced in the USSR, as well as with prices per gram of gold.

The first stamp on gold was placed in the middle of the sixth century in an ancient country with the beautiful name Lydia. The state government considered this measure mandatory to ensure the protection of the population from scammers.

How is a sample determined and is there 825 among them?

Any sample indicates the pure percentage of metal contained in the product. The rest is impurities. The composition and amount of impurities determines the color of the metal, appearance, allergenicity, and iso-resistance.

Gold jewelry in the world has dozens of hallmarks, which are measured using metric and carat systems. In Russia, 375, 500, 583, 585, 750, 958, 996, 999 samples are officially permitted. Platinum has a purity of 950, palladium - 500, 850. Here we do not see the 825 purity, which interests us. There are six hallmarks of silver: 800, 830, 875, 925, 960, 999. The standards for these hallmarks are set by Russia, and there is no 825 hallmark here either.

But despite this, we find 825 sterling jewelry on sale among jewelry. These are most likely scammers who, under the guise of silver, sell products with titanium and aluminum oxide, that is, chrome-plated products. Perhaps the 825 test exists, but it is not widespread and is used in other countries. Some argue that there used to be silver with such a hallmark.

Silver alloys in jewelry

What is it - 56-carat gold?

What is it - 56-carat gold? It is a metal measured by the spool system relative to the purity of gold. Previously, in Tsarist Russia, one pound was taken as the basis of measurement, which was equal to 96 spools. The 96th sample was considered the highest, which did not contain any impurities at all. However, it was practically not used to create jewelry. More common was the 56 standard of metal, which indicates that the alloy contains 56 spools (that is, pure gold) and 40 parts of additives (mainly silver, copper, palladium). Impurities were necessarily used in an alloy to give it specific properties, such as hardness, ductility, or wear resistance.

What is it and does it exist?

When choosing a product made of precious metal, the first thing you should pay attention to is the presence of an assay mark . But much more often, buyers prefer to distinguish silver from gold by completely different parameters, for example, by the color of the product; there is a big mistake in this approach.

However, if the stamp indicates 825 standard, you shouldn’t be happy either. In this case, we are not talking about a noble inert metal with a complex multicomponent composition.

The hallmark, or more commonly known as the hallmark, on jewelry is a valuable source of information. It is this that determines what percentage of pure metal is contained in the product. The higher this indicator, the less is left for impurities that affect:

color characteristics;
hypoallergenic;
wear resistance;
visual parameters.

In Russia, an official classification of precious metals has been established, among which are gold, platinum, silver, and palladium. The 825 grade product is most often sold as silver. Accordingly, it is precisely this that has to be considered as a metal for comparison. A number of silver-based jewelry alloys are officially approved in

720 sample. Not considered jewelry, used for industrial purposes. Metals of this group are refractory and have a brighter color. The test is performed extremely rarely.

800 sample. An alloy containing 80% silver is considered base due to a pronounced yellow impurity. Metals of this group lend themselves well to casting, and they are used to make dishes and cutlery.

830 sample. In terms of properties and characteristics, such alloys are almost similar to those of the 800th sample. The only difference is the percentage of pure silver in the composition.

What is it - 5s5 gold?

What is it - 5s5 gold? A similar mark is sometimes found on jewelry. In reality, such engraving does not exist. If you see the value 5s5 on the product, this indicates the purity of 585, but the central digit has been erased due to active use.

It is advisable to refuse to purchase 5s5 gold only if you are not sure of the seller. Nowadays, some people deliberately place such a mark for fraudulent purposes. A fake is usually made of gold of a lower standard or from a completely different alloy. It is almost impossible to determine by eye whether this is a fake or real 585 gold. This is only permissible experimentally using a reagent and in a chemical laboratory.

How to spot a fake?

Since products of “825 standard” are most often sold as silver, it is also worth checking the quality of products specifically for the content of this precious metal in the composition. There are objective criteria by which you can identify a fake.

Hallmark. It should be easily readable even without a magnifying glass or other devices. If the stamp shows numbers that differ from the variants entered in the official register, it is better to refrain from purchasing the product.
Reaction to chalk. In this case, the silver will darken. Other metals will remain light.
Reaction to contact with tiles. It is enough to drag a metal product across the surface. If it is gold, there should be no reaction.
Reaction to contact with palms. If dark spots appear on the surface of the product after it, you should refuse the purchase. This reaction indicates a high percentage of zinc in the composition.
Origin. Often, sellers of pseudo-precious metal claim that the goods were delivered from abroad. But if the sample is marked according to Russian standards, it must comply with them. Among the stamps that are relevant in foreign countries, there are also no such meanings - the closest option is 826, which is found in Norway and Denmark.

Taking these points into account, it is possible to recognize a low-quality product made of precious metals sold under the guise of 825-sterling silver.

It is worth remembering that in the modern classification such a percentage of metal does not occur. Accordingly, it is better to refuse to purchase jewelry.

Price of 1 gram of metal

The price of 1 gram of 56-carat metal corresponds to the cost of a gram of 585-carat gold. But remember that rates are highly dependent on a number of factors, including:

presence or absence of precious stones;
marks of the master of that time (jewelry created by great masters is much more expensive);
information that the item was owned by famous personalities;
year of manufacture.

If the jewelry is recognized as an antique, its value will be determined individually. In all other cases, prices will correspond to those shown in the table.

Try	Market value of 1 gram	Price per 1 gram of scrap	Jewelry value of 1 gram
56 sample	1671 ruble	1504 rubles	3000 rubles
5s5 sample	1671 ruble	1504 rubles	3000 rubles
585 sample	1671 ruble	1504 rubles	3000 rubles

Now you know what gold standard 56 is in the spool system, what metric and carat it corresponds to. Remember that the prices for the 56 sample, the corresponding 585 or the erased 5s5 are identical. The exception is products with precious stones or created by great masters.

Sample system

There is no single system by which a sample is determined. In Russia and the CIS countries it is one, in the USA it is another. Let's take a closer look at the basic units of measurement.

Metric system

The classification was introduced in the Soviet Union. It indicates how many grams of pure gold the product contains. This system is still used today.

According to classification, 6 samples are produced:

375 standard – 37.5% metal – bright yellow decoration;
500 sample – 50%;
585 sample – 58.5%;
750 sample – 75%;
900 sample – 90%;
999 sample – 99.9.

Jewelers consider the 750 standard to be the most successful, since it contains the optimal ratio of silver, nickel and gold during manufacturing, which makes the alloy durable and elastic. The sample is especially highly valued by smelters, but it is not often released due to its high price. Jewelry made from it does not fade or wear off.

The most popular standard is 585. Almost all women's gold rings with diamonds and other precious stones are made with it.

Carat system

Found in the USA and some European countries. The carat is the official unit of measurement for gemstones. It is equal to 0.2 g. However, the sample itself is calculated differently. The product is conventionally divided into 24 shares and indicates how many parts are pure metal. For example, 23k purity means that the jewelry is divided into 24 parts, and 23 is the composition of pure gold.

Unlike the metric system, there are more measurements in the carat classification: there are 10 of them. Thus, the 375 standard corresponds to 9 carats, and the 750 standard corresponds to 18.

When choosing jewelry, look carefully at the details. It is easy to find out the gold purity number. On earrings it is placed on a hook or pin, the inner or outer side of the hook is marked in rings, and on bracelets the stamp can be found near the clasp or on the link that connects the lock to the main part.

What does a gold sample look like?

The gold standard in Russia has a certain standard. It always looks the same, only the meaning changes.

The gold standard in Russia always contains the image of a girl in a kokoshnik.

K - To the left of the image is a letter of the Russian alphabet. She points to the Assay Supervision Inspectorate where the jewelry was tested.

585 - gold content

Ways to recognize fake jewelry

First you need to consider the jewelry.
It must have a special marking that is responsible for the authenticity of the gold. The hallmark or carat weight must be stamped. To facilitate inspection, it is advisable to use a magnifying glass. It is not always possible to distinguish the mark on antique metal. In the modern world, they have learned how to test gold on fake gold, so this method is not always successful. Over time, the gold plating wears off. You need to look at the edges of the product. If other metal is visible in the areas of wear, the item is not entirely made of gold.

Checking the product for bite

Previously, films were often shown where gold coins were tested for their “tooth”. And for good reason. After all, this way you can check not only coins, but also gold jewelry. For example, a ring or earring. The product must be pressed with your teeth. Now look at him. Real gold will leave teeth marks. The deeper the bite, the higher the test. However, we must not forget that lead is very soft, so it will also leave traces.

Ceramic check

Fake gold is easy to detect using this method. This test must be carried out very carefully as it is easily scratched. To do this, you will need an unglazed ceramic plate, that is, not covered with anything. Swipe the gold over it with light pressure. What is visible? The gold stripe is a natural product, the black stripe is a fake decoration.

Magnetic check

First you need to purchase a magnet. The one that hangs on the refrigerator is very soft and is not suitable for dough. The magnet must be a real, heavy one that interacts with the metal. Gold is never attracted. Therefore, feel free to bring the jewelry to the magnet. If she is attracted, then you are holding a real fake. There are cases when a magnetically passive component is added to a product. Then you can confuse gold with a fake. How to distinguish gold in such cases? Try the following method.

Application of nitric acid

Nitric acid will help identify fake gold from real gold. To do this, place the product in a metal container without stains. Next, you need to drop nitric acid from a pipette onto the product. If the gold changes color and becomes greenish, then you are conducting an experiment with ordinary metal. The gilded product takes on a milky hue. If the gold is real, then no reaction will take place.

Sound test

If you take a gold item and throw it onto the surface of the table, then the real metal will ring loudly, like crystal. For such an experience, rings, earrings, but not long jewelry (chains, bracelets) are suitable.

Vinegar test

Pour some vinegar into the container and place the decoration there. Nothing bad will happen to real gold, but fake gold will darken in two minutes.

Iodine test

Iodine is a very good test for the authenticity of jewelry. To do this, you only need to apply one drop to the inside of the product. Gold will remain unchanged. The fake decoration will darken. It can turn either light gray or black.

ANY CHEMICAL TEST IS POSSIBLE ONLY ON THE SURFACE OF THE DECORATION. THE INSIDE IS CHECKED WHEN A PERSON IS READY TO DESTROY THE PRODUCT.

You can also ask experts how to distinguish gold from a fake, who will help you quickly and using several ways to determine whether the jewelry is real. Gilding is almost real metal.

Method of applying gold sample

The mechanical method of applying a sample is the most common in the world. Until recently, this was the only option for hallmarking jewelry. It is applied by mechanical deformation of the gold surface using a harder cliche.

The laser method of applying samples began to be used not so long ago. Such a sample can only be found on modern jewelry. It is applied using special equipment, burning a pattern onto the surface of the gold. The piercing depth is not large, so the laser mark may be erased over time.

The electric spark method of applying a sample was a transitional link from mechanical to laser. It differs from laser in its deeper application, which is why it is more durable.

Branding methods

Previously, jewelry was marked with a convex test. Later, its appearance was changed, as was the method of application. Technologies used today:

impact method: was popular earlier, based on mechanical impact on metal with a self-made impact stamp;
electroerosion (electric spark method): this option has many advantages, they note that there is no risk of severe deformation of the metal, creating zones of concentration of internal stress, as a result, they receive a mark with a depth of 0.1 to 1 mm, and the best characteristics are distinguished by a test made on a hot, colored metal, as well as when applied using a press;
laser engraving: the technology ensures high precision of execution, which allows it to be used for making micro-stamps, the laser beam is considered the thinnest tool, it is used to make signs up to 1 mm in size, this is the method that has become widespread today, in addition, there is another factor that indicates about the wide capabilities of the laser - non-contact implementation.
