Gold jewelry has been valued for thousands of years. They are characterized by a yellow color and bright shine. Products made from noble metal are presented in a wide range and differ in composition. In turn, the characteristics of the components determine the properties and appearance of the jewelry. One of the most common varieties is 750 sample.
The alloy contains gold and alloy. However, the ratio of additional components can be different, as a result the metal acquires a shade from white to red. Different options are popular in different countries. Accordingly, the cost will differ.
Fineness 750 - what kind of metal is it, what does it look like, the concept of fineness
To determine the quality of the metal, analytical methods are used, with their help testing is performed. This allows the consumer to determine which group a particular material belongs to. In addition, the quality of the alloy is assessed based on the ratio of different components.
Accordingly, a sample is a result obtained as a result of the application of one of the existing analytical methods (based on determining proportions, weight components).
First of all, 750 gold standard determines the amount of precious metal. Secondly, thanks to this designation, you can find out the proportion of ligatures included in the composition. So, for 1000 parts by weight there are 750 parts of gold. The rest is additives. A significant proportion of the precious metal determines the properties of the alloy: it is characterized by a yellow color, low Mohs strength, but the products are easy to polish.
World gold purity systems: metric and carat
The sample makes it possible to find out the amount of precious metal relative to the entire mass of the alloy. In this case, a different principle is used for calculating the shares of gold, which determines what the designation of the alloy will be. From the moment when the concept of testing was introduced, and the first method of carrying out this procedure was developed, until today, different systems have been used:
- metric;
- carat;
- spool;
- lot.
The first 2 of these were introduced later. The metric system was used in the USSR (since 1927), this system replaced the spool system used in Russia in recent centuries. It is based on the determination of the precious metal content in 1 g of alloy. According to the metric system, 750 fine gold is one of the types of valuable material, other options: from 375 all the way to 999.
The carat system is a foreign system based on determining the amount of precious metal, taking into account a certain proportion of the weight of the alloy: 0.375-0.999. In this case, the minimum part (0.375) corresponds to 9 carats, and the maximum (999) corresponds to 24 carats.
Interesting: If a product hallmarked according to the karat system is imported into Russia, it is necessary to put a stamp with hallmark according to the metric system; for comparison, in the UK, both methods for determining the amount of gold are used.

How many carats are in 750 sample
750 pieces are not as common as lower grade pieces (like 585). But they are more expensive, these are luxury jewelry. They should be worn with care to avoid damaging the soft metal surface.
However, 18k yellow gold can be considered not as an element of decoration, but as a way of investing.
You can buy and sell such jewelry for a large sum. If the product bears a mark according to a foreign testing system, you need to find out how to decipher the designation. Thus, 750-carat gold in composition and properties corresponds to an 18-karat product.
Where was the 583 sample used?
The test was used for almost all types of jewelry. This includes bracelets, pendants, chains, and rings. Large rings were especially popular; they could weigh more than some bracelets. If you find them now, their appearance will be almost identical to how they were when you purchased them.
At the moment, this sample can be found rarely, since it is not accepted internationally and is considered a second-class alloy.
Now people are well aware of this, and in order not to risk their reputation, they do not buy such jewelry.
But at the same time, gold is popular in certain circles. Many people order custom jewelry made from this gold. Things made in the old style are especially beautiful. An alloy is used for them, which will give a reddish tint.
At the moment, if the sample is used, then for the following items:
- wrist watch,
- accessories,
- pens,
- keychains,
- piercing earrings,
- souvenirs,
- products for decoration.
Marking. Image of the Russian mark
In Russia, 750 gold is assayed in a certain way. This makes it possible to distinguish it from platinum group metals, silver, and other precious metals. In simple words, a stamp is a sign of quality that confirms the gold content in a certain amount. On the products you can find a name tag - the manufacturer's trademark.
Marking, branding and assaying of jewelry
The presence of a state hallmark is mandatory; it contains information:
- hallmark(gold 750);
- hallmark;
- code of the State Assay Supervision Inspectorate (M).
Reason for popularity
Gold of 583 and 585 samples still remains popular in Russia. It is almost impossible to distinguish them; only a professional can do this, but more on that a little later. What made this gold so popular and sold even in our time?
In the Soviet era, products were largely valued because of their reliability and resistance to wear and other external irritants. The jewelers understood this very well and worked to achieve the desired result. Those who did not neglect the care of the condition of the products, until our time, were able to preserve them in the form in which they were at the time of purchase.
Interesting! The most purchased standard in Europe today is the 750 mark. She is also popular among accomplished people in Russia.
Advantages and disadvantages of 750 white and yellow
If 750 gold is considered, it must be taken into account that the use of different combinations of alloys can produce white and yellow colors. It is necessary to compare them according to the main parameters.
For example, the advantages of yellow metal include:
ease of polishing;
high value of jewelry, which allows you to invest in them;
ease of processing, thanks to this it becomes possible to quickly restore the appearance of products;
resistance to aggressive environments;
production of various jewelry: earrings, rings, bracelets, chains, etc. are made.
Disadvantages of this material:
softness;
deformation due to intensive wear - deep scratches quickly appear;
Regular rhodium plating is necessary, which will allow the jewelry to remain attractive longer.
750 white gold has a number of features that make the metal stand out from others.
Advantages:
higher hardness;
noble color;
maintaining attractiveness for a long period;
wear resistance.
Flaws:
increased strength in most cases is an obstacle to the creation of jewelry with complex designs, which is due to low ductility;
high price.
Composition and properties
Alloying components improve the performance characteristics of the alloy. The raw materials of the brand in question contain 25% impurities. Additives not only increase the values of hardness and strength, but also change the shade:
- Yellow color is inherent in an alloy containing 17% silver and 8% copper.
- Pink color is obtained with 12.2% silver and 12.5% copper.
- The stunning platinum white color is created by 5% silver and 20% nickel.
Gold marked 750 is less resistant to environmental influences than other grades. This is due to the smaller amount of ligature compared to other varieties of gold.
High-grade noble metal is in demand in the jewelry market due to a number of advantages:
- malleable to processing, it can be used to create complex jewelry;
- polishes well;
- contains a high content of pure gold.
However, the advantages dictate the disadvantages. This metal is prone to deformation due to the slightest load. The product needs care, otherwise it loses its shine and attractiveness.
Jewelry made from high-quality raw materials should be stored in a separate box, in an additional velvet bag. The metal is extremely soft and can become deformed or scratched when in contact with other products.
Widespread use of 750 gold
Precious metals are in demand in many areas. Also, 18k white gold is used for the production of various products, due to its physical properties. This metal is used in jewelry, various industries, and dentistry.
It is used in the manufacture of electrical components.

Why jewelers love him
Yellow metal 750 is fusible and quite soft. Thanks to this, it is easy to work with, it is easy to polish jewelry, and give the material the desired shape. It is used in the production of decorative elements for luxury stationery, household items, and electronics.
Some things are made entirely from this precious metal: pens, cufflinks, watches, etc.
White gold
An alloy based on the yellow precious metal and platinum, palladium is one of the most in demand today. It may look different depending on the presence of coating. It is easy to determine whether there is a layer of rhodium by looking at the shade: such jewelry is distinguished by a purer white color and shines. But the surface must be periodically restored, as it loses its properties. 18k white gold looks best when combined with:
- diamonds;
- red, yellow inserts;
- unusual carving.
Uses of gold
According to historical information, gold is the pioneer metal with which humanity interacted. Acquaintance with him took place 2-3 thousand years ago, as evidenced by the jewelry found at the excavations. There are also references to this precious metal in the Iliad and the Bible. Gold also aroused great curiosity among alchemists, who often sought ways to transform metals into precious metals, which were credited with great power.
In the modern world, gold has several functions:
- in commodity production it performs the function of money;
- in art it is used for jewelry work;
- in medicine it is used as components of some drugs;
- also used in the chemical industry and electrical equipment.
The cost of 1 gram of gold is 750
The price of the precious metal is constantly changing:
| 999 standard (Central Bank of the Russian Federation), rubles. | Market price, rub. | Metal for scrap, rub. | Jewelry stores, rub. |
| 3889 | 2917 | 2625 | 4083 |
Moreover, the price of earrings, necklaces, rings or other jewelry yesterday, today and even tomorrow may also differ. To determine the average cost of 750 precious metal, you should use the formula:
Central Bank exchange rate (cost of 999 fineness) x 0.75 = price of 1 g of 750 fine gold.
Pricing Aspects
The main factor is the price set on the London Stock Exchange. It determines the magnitude of changes in the value of precious metals around the world. In addition, if 750 gold is considered for purchase, the price per 1 gram will depend on other factors:
- prices for precious metals set by the Central Bank of the Russian Federation;
- production expenses;
- jeweler's work.

Price
For 2021, the price of 583 gold and 585 gold is practically the same. It ranges from 2900 to 6000 rubles. As for the pawnshop, the price per gram will not exceed the threshold of 1,700 rubles.
In Ukraine, the situation is similar: both samples are sold and bought at almost the same price. Here you can get about 1000 UAH per gram, but the amount more or less directly depends on a number of indicators, for example, on the manufacturer. In a Ukrainian pawnshop they will give no more than 600 UAH per gram of Soviet gold.
How to choose real 750 gold
If you have not previously had experience purchasing high-quality products, you must take into account the following recommendations:
- you should buy jewelry from trusted manufacturers, in large jewelry stores;
- if you have any suspicions about the low quality of the products, you can ask for a certificate;
- you need to inspect the jewelry: there should be no damage on the surface, pay attention to the weight (gold jewelry is heavier than silver), such jewelry has a bright shine;
- the shade may be different (not pure yellow, but with a pinkish, green tint), but this does not mean low quality, the metal simply differs in the ratio of the ligature.
Authenticity of the mark
Of course, you should pay attention not only to the digital designation when purchasing a product, but also to the shape. Each country of origin has its own stamp forms. On Russian objects, the symbols are made in the form of a female profile or in the form of a hammer and sickle on a five-pointed star. How to check whether your product has a genuine mark and hallmark or not. To do this, you need to clean the surface of the jewelry and apply it in a special way so that strips of metal remain on it. After that, chemical reagents are applied to them one by one, each of which is intended for a specific type of alloy. Today on the Russian market there are reagents for all possible alloys. If the content of the metal in question in the alloy is as specified, the color of the yellow streaks will not change and they will not disappear. If the gold stripes completely disappear, this indicates that there is no metal in the product at all.
Where can you buy and sell 750 gold today?
Available options for purchasing jewelry:
- stores: online and offline;
- pawnshop: you should choose this option if it is not possible to purchase a new product, but you need to inspect the appearance of the jewelry (how well the former owner took care of it).
In addition, private purchasing is available today, but the price per 1 gram will be significantly lower. Other sales opportunities:
- store: you can return the product to get a discount and purchase a new one;
- pawnshop.

Sample history
Since the times of the Soviet Union, people have become accustomed to believing that 583 gold is the best. But this is not entirely true: those who understand alloys immediately understood this. But for many ordinary people this was a big discovery. Evidence that gold is not of the highest quality is its deteriorating appearance, namely darkening many years after its purchase.
But Soviet jewelry has another useful feature - it is very durable and difficult to deform. This was done so that the thin rings, which were one of the best-selling rings at that time, would not bend and confuse buyers. If you compare the price per ounce of gold then and now, it has increased by $1,400. Given the rise in price, people are trying to buy products of the highest standard.
TOP 5 ways to maintain the external gloss of 750-sterling jewelry
Caring for 750 grade jewelry and 585 grade jewelry is different. It is necessary to study the question of how to clean and polish products in order to maintain its attractiveness. TOP 5 important nuances:
- Do not allow the gold alloy to come into contact with chemicals. To do this, you need to remove jewelry before doing household chores, applying cosmetics, or taking a bath or shower.
- It is necessary to minimize contact of the precious metal with human sweat. You should not wear gold jewelry while playing sports.
- You can maintain the shine of your jewelry using wool or felt: you need to periodically rub the items without making significant effort.
- To care for jewelry, use a soap solution with the addition of a few drops of ammonia. This will help maintain shine.
- To preserve items, use a box in which jewelry can be kept separately from others, and on a soft backing.

Quality of gold products
Gold has a chemical ability: in its pure form it is not subject to oxidation and many other chemical influences. But when combined with other metals, these properties become different. It is generally accepted that gold alloys of purity 750 and higher are subject to little corrosion. It is worth noting that when producing an alloy, gold may be distributed unevenly, and then the area in which there is little or no gold may be corroded. The jewelry in this place will be dull.

18k yellow gold – not a fake?
Expert opinion
Pribrezhny Gennady Valentinovich
Jeweler 6th category
Judging by the reviews, many people doubt the authenticity of jewelry made of light yellow metal. In fact, this is also a gold alloy and is not a fake. However, it contains a minimal amount of copper, and silver predominates in its composition (except for gold).
Products and decorations
Items with higher markings belong to the premium class; no one wears them in everyday hustle and bustle. These jewelry items are for special occasions. Plasticity allows you to create complex carved elements and openwork patterns. The beauty of an object depends on the skill of the jeweler.
High grade noble metal is not involved in mass production. It is mainly used to create one-off, exclusive products with precious stone inserts.
Impurities in certain quantities expand the range of shades of the sample. In the traditional version, the raw material is yellow and is used to make wedding rings, earrings, and chains. Nickel and palladium as alloys color the alloy white. This material is valued for setting diamonds. The cost of the resulting products is incredibly high, especially if platinum is present in the gold alloy.
