Popular 585 gold hallmark - good or not: how it looks, formula of ideal alloy composition in percentage, use of precious metal, choice and care of it

Among the most popular precious metals is an alloy containing more than 50% gold. It is distinguished by its best characteristics. The metal is valuable and quite strong. The alloy is the gold standard. It represents the best combination of gold и ligatures. By comparison, pure precious metal without additives is very soft, quickly damaged.

Accordingly, it cannot be used to make jewelry.

This explains why 585 is so widespread. Products of this kind look almost the same as pure gold, which is due to a special combination of additives. However, they last longer and retain their attractiveness.

585 hallmark - popular in Russia: what it looks like, the reasons for its appearance and demand

It may seem that 585 gold is the only precious metal of its kind. But this is not quite true: there are several variations of this alloy, but all of them contain the same amount of the main component - Au.

The ratio of ligatures differs, which causes a slight change in properties, as well as the appearance of products.

Alloy composition

Technically 585 gold standard Alloy has been in use since 1994, when it was decided on the legislative level not to use branding 583. In composition they are practically identical. Both previously in the USSR and today in Russia, the base of the alloy was gold.

According to the standard, the percentage of this component is more than half. The rest are additives. And the alloy can contain both precious and non-precious metals. Not only the appearance of the article depends on the type of these components, but also its value.

When the purpose of buying a 585 gold, the composition of the alloy in the percentage:

  • precious metal - 58.5%;
  • additives - 41.5%: silver, platinum, copper, nickel, silicon, zinc, palladium, etc.

The properties of gold: the formula for the perfect alloy

Despite the insufficiently high content of the noble metal, the alloy is not considered bad. On the contrary, it is the best option that combines all the wishes of consumers. The properties that exhibit gold alloy:

  • density is 12.8-14.76 g/cm5The composition of the 585 gold can be determined more accurately by knowing the composition of the gold;
  • hardness: the metal does not deform under moderate loads;
  • Plasticity: Due to the fact that the composition can include different additives, it also changes the ability of the metal to change shape, for comparison, pure gold is soft, but brittle, after the introduction of a 585 alloy alloy alloy has become plastic, but it keeps its shape;
  • Melting point: the value of this parameter for gold without additives is 1337 ° C, but when the structure changes, so do the properties, and the jewelry alloy containing a ligature, most often melts at lower temperatures.

How many carats in 585 gold

Today in Russia there is only one system for assessing the purity of the gold alloy - metric. Contents 585 precious metal was determined with its help. In this case, the task was to find out the amount of gold in 1000 weight parts. Accordingly, 585 g is obtained. Carat. It also implies the need to determine the number of alloy parts in a given amount of precious metal. However, not 1000 weight parts are used, as in the metric system, but 24 carats. If the item has a proof (determined by one of the methods), you can translate its value:


Wide range of colors

When it says that the gold alloy contains additives, there are several features to consider:

  • Nickel is not used in the manufacture of jewelry, because the metal promotes allergies;
  • Palladium, as well as platinum, are components whose use leads to higher metal prices, so they are not added to the composition very often.

Is gold assay 585 good or not?

Opinion of an expert
Pribrezhny Gennady Valentinovich
6th class jeweler
The precious metal branded 585 is not just good. It is one of the best. This is because metal with a low gold content (less than 585), of medium purity, is inexpensive and has little investment value. Conversely, alloys with a higher proportion of Au are expensive, but cannot be used on a permanent basis.

Composition of 585 gold in percentage?

Opinion of an expert
Mikhail Petrovich Grishanov
Jeweler, Director of Grishanov & Co.
The jewelry alloy is valued because of the large amount of gold content. The proportion of such metal is 58.5%. So, the amount of additives is less than half (41.5%). It is also noted that the material consists of silver. This is the most common type of ligature. In comparison, the introduction of platinum group metals into the composition contributes to an increase in cost, and therefore is used only if it is necessary to obtain products of white color or when products of a high price category are produced.

When did the 585th gold hallmark appear in Russia?

Opinion of an expert
Pribrezhny Gennady Valentinovich
6th class jeweler
During the time of the Soviet Union, a different kind of assay, 583, was in effect. But it was not quoted all over the world. This can only mean one thing - after the collapse of the USSR it was time to move on. The transition from the old assay format to a new one took place. In 1994, the updated version was already actively used, but the old one had not yet been completely withdrawn.

How much pure gold is in 585?

Opinion of an expert
Mikhail Petrovich Grishanov
Jeweler, Director of Grishanov & Co.
The amount of the precious metal Au is encoded in the stigma. Both previously and nowadays, the metric system of determining the content of the main component is still used. This could mean that 1,000g of gold alloy contains 585g Au. Since then the noble material is accepted on the world market without any extra difficulties, and an adequate price is offered for it.

What is the difference between a 583 and a 375 proof?

Opinion of an expert
Pribrezhny Gennady Valentinovich
6th class jeweler
The difference between the products is the gold content. The 585 metal is not considered low-grade, which distinguishes it from the 375 grade. The latter option is a budget option. It is more difficult to sell it at a pawnshop. But the strength of such an alloy is really high.

What kind of gold is better: 585 or 750?

Opinion of an expert
Mikhail Petrovich Grishanov
Jeweler, Director of Grishanov & Co.
You have to define the goal first:

  • If it is important to buy a particularly valuable precious metal, which may contain expensive components (gold, silver, palladium or platinum), then you should buy the material with the stamp 750, but it is better not to wear such products every day;
  • When you want beautiful jewelry that is durable, easy to clean, it is recommended to consider items of 585.

Is it worth investing in the 585

Jewelry 585 does not belong to the low-grade and contains a significant proportion of precious metal, despite this experts do not recommend investing in them. It is best to consider coins and bars. Reasons:

  • Jewelry with the 585 mark often has to be scrapped, as the expansion of the assortment has eliminated the need to buy second-hand items.

Important: The price of the precious metal when trying to sell it as scrap is much lower than the average cost of new items, which makes it impossible to sell the jewelry profitably.

Going on vacation, there is an opportunity to buy jewelry abroad. It is believed that they are cheaper there. But the difference in price is just a way of attracting the attention of customers. As a rule, such countries use a karat system of branding.

Inexperienced in translating the numerical value of the sample from one system to another, the buyer makes a purchase, believing that he is left with the winnings.

Lawyer's Commentary

Avanesyan Grisha Karenovich
Avanesyan Grisha Karenovich
Lawyer, head of the law firm "Avanesyan and Co.
The difference in methods of determining the purity of the precious metal in different countries prevents one from obtaining a high quality product. I know of many cases when people from my country have been in such situations. Sometimes even the presence of a hallmark or certificate does not help (there are even fakes). I would advise not to buy jewelry under such conditions. But if you have such a need, I recommend that you look at the weight of the jewelry piece. Gold is usually heavier than silver or costume jewelry.
