Many lovers of gold jewelry are still unaware that these items are made of impure metals. The true amount of precious metal is indicated by samples<\/a>.<\/p>\n\n\n\n

It is generally accepted that USSR gold<\/a> is bought from precious metal dealers much more than it is today. After all, it has been historically proven that Soviet jewelry is more resistant to the aggressive effects of acids.<\/p>\n\n\n\n

Let's try to figure out how Soviet noble metals are better than modern ones. Let's find out which one alloy<\/a> more reliable and beautiful.<\/p>\n\n\n\n

What was the gold standard in Soviet times?<\/h2>\n\n\n\n

In 1922, during the formation of the USSR, the system of gold samples<\/a>developed as early as 1798. At that time the calculation was based on the Russian pound, which included 96 spools<\/a>.<\/p>\n\n\n\n

\"583<\/span>

Since 1927 it lost its significance. It was adopted metric system<\/a>. According to it, the assay shows the number of milligrams of noble metal in 1g of alloy per 1 kg. This calculation was borrowed from Europe. <\/p>\n\n\n\n

\n

Equal settlement with foreign countries allowed the Union to develop in the foreign market of noble metals. <\/p>\n<\/blockquote>\n\n\n\n

To do this, the process of measuring the assay of gold for jewelry in the USSR was adjusted to generally accepted standards. Sample selection<\/a> was small. The country wanted to adopt a uniform standard gold<\/a> for all in the form of 583<\/a>.<\/p>\n\n\n\n

583 hallmark - the \"gold standard\" of Soviet times. History of appearance and composition of the gold standard in the Soviet Union<\/h2>\n\n\n\n

The 583 grade can be safely called the most famous in the USSR. Its appearance was connected with the formation of the metric system in 1927. Based on the presence of 58.3% of gold in it, it was called \"583\". The remaining 41.7% of composition is due to ligatures. Metals such as copper, palladium and silver<\/a> in their own way affected and modified the metal in color and strength.<\/p>\n\n\n\n

\n

To maintain quality control of jewelry in the early 70's was approved by GOST on their percentage in the composition.<\/p>\n<\/blockquote>\n\n\n\n

A small amount of copper gives the metal a pleasant reddish glow. But if it is too much, the metal will become brittle, because copper is soft.<\/p>\n\n\n\n
