Today there are many kinds of jewelry made of alloys of different compositions. They differ in the breakdown. The modern options are: 375, 500, 585, etc. Among them, there is no longer mentioned the variant that corresponded to the standard USSR<\/a> - 583 gold hallmark<\/a>. Despite the gradual transition to other types of products, many people still have jewelry from those times.<\/p>\n\n\n\n

Such jewelry has its own advantages and disadvantages. But the transition from the most common hallmark in the post-Soviet countries (583) to the European quality standards (585) was connected not with the characteristics of the precious metal, but with the changes in the structure of the state, which required transformations in all spheres, including jewelry.<\/p>\n\n\n\n

Gold of the USSR - 583 sample with a star, what is the value<\/h2>\n\n\n\n

Sample<\/a> is a numerical designation given to a precious metal when determining the content of its components. Items 583 corresponded to the gold standard adopted in the USSR. The assay was introduced during the transition to the metric system of assaying (in 1927). This made production easier: most items had a similar composition, the decorations differed mainly in their hue. <\/p>\n\n\n\n

\n

The bulk of the alloy was gold (58.3%), with the rest being a ligature.<\/p>\n<\/blockquote>\n\n\n\n

Today you can come across a piece of jewelry with a star. They do not have a modern hallmark. But there is still a branding on the back of the items - a five-pointed star, with a hammer and sickle on the inside. This is what a Soviet 583-proof ring looks like. One should not immediately suspect a fake. <\/p>\n\n\n\n

\n

Items of this type are authentic, but somewhat outdated. Their main value lies in the characteristics. If there is a star on the ring or bracelet, it means the metal is durable, not prone to tarnishing, lasts a long time, does not lose its appeal.<\/p>\n<\/blockquote>\n\n\n\n

Table: composition and properties of the alloy<\/h2>\n\n\n\n

When comparing gold<\/a> 583 different species, it is noted that the reddish alloy was the most popular. Its composition included copper (a substantial proportion). Despite containing the same amount of precious metal, the alloys differed in their properties:<\/p>\n\n\n\n

The difference<\/a> between metals of the same category (gold 583) is significant, and it consists mainly in shades:<\/p>\n\n\n\n

Star branding, how it looks, history of origin, what it means<\/h2>\n\n\n\n

Today, gold 583 is not used for mass production of jewelry, otherwise it would be possible to find the appropriate mark on it. Its main distinguishing mark is the star-shaped stamp. Earlier (before 1958) another marking was used - the head of the worker with a hammer. The hallmark was changed, after which it quickly became recognizable. <\/p>\n\n\n\n

It is a star containing a sickle and hammer, which means belonging to the Soviet Union, as the main elements of the coat of arms are inside the assay. <\/p>\n\n\n\n

\n

At the same time the marking of the Assay Office changed. Cyrillic letters began to appear on the decorations of those times.<\/p>\n<\/blockquote>\n\n\n\n

583 proof in gold and carats<\/h2>\n\n\n\n

Alloy containing 58.3% of precious metal can get different designations, 583 gold assay with an asterisk is not the only option. The properties remain the same, but the branding changes. A different combination of numbers may appear on the metal - according to the carat system. With the help of the table, it will be easy to find out the deciphering of the designations as well spooner<\/a> systems:<\/p>\n\n\n\n

Important: The highest values correspond to a greater amount of precious metal, which means that as the proportion of gold decreases, so does the value of the product.<\/p>\n<\/blockquote>\n\n\n\n

The Mystery of the Popularity of the Star-Spangled Assay<\/h2>\n\n\n\n

Soviet 583-gold, like many other things of that era, was monumental and was created to last for many years. This also applied to jewelry. Earrings, chains, rings, bracelets, watches, sets jewelry<\/a> etc. - They corresponded to GOST, the technological process of production was not violated. <\/p>\n\n\n\n

\n

The share of marriage was minimal, practically tending to zero. In addition, gold 583 had many advantages. The main advantage was considered to be the long service life of products. This was due to its high hardness and resistance to mechanical stress.<\/p>\n<\/blockquote>\n\n\n\n

As a result, earrings and rings did not change their appearance. This can be said about the products of different colors - white, yellow, etc. But the numerous advantages would not have mattered much if the price had been high. The price of a troy ounce of gold during the Soviet Union was 200-300$.<\/p>\n\n\n\n

The reason for changing the hallmark to 585. Which is better. The first GOST for gold<\/h2>\n\n\n\n

First of all, it is necessary to understand where the number 583 came from, if other assay systems used alloys with a similar composition, but a different designation - 585. In this case, the translation between systems plays a key role. Features of the calculations:<\/p>\n\n\n\n
