Jewellery is always prestigious and stylish. The fashion for the acquisition of elegant pendants, ornate chains and beautiful elegant rings never fades. A huge number of jewelry craftsmen work daily to create new products that attract the attention of potential consumers. It is worth noting that items made of gold are the most popular among jewelry lovers. At the same time, products containing 100% pure material are rare. This is due to the properties of the precious metal. Gold is a very soft element. If you do not add other components to it, objects made from it turn out to be unstable and quickly lose their shape. Therefore, even to create jewelry of the highest quality, it is customary to use alloys, which later get the name “sample”. As a rule, in such compounds, along with gold, there is another component: silver, copper, nickel, etc.
Adding extra ingredients
Depending on shareprecious metal in the composition of jewelry is also distinguished by various samples. So, if the product contains up to one percent of a foreign element, this product is considered the most “clean”. The sample of such an item is the 999th. When in the entire volume of the alloy twenty-five percent is occupied by an admixed element, and seventy-five is gold, then such a product will bear the label "750". 585 test means that fifty-eight and a half percent of the precious metal is present in the created item. The rest of the composition is impurities of copper and silver.
History of Appearance
It is noteworthy that the 585 sample came into use relatively recently: in 1989. What was the impetus for the creation of this alloy? In the USSR that existed at that time, products with 583 samples were especially popular. This alloy was called "pure gold". However, in Europe, one gram with such a breakdown was given too low a price, because in terms of its characteristics it did not reach the minimum British unit - fourteen-carat gold. In order to equalize the cost indicators, it was decided to slightly change the composition of the 583rd sample. Instead of 58.3% gold, 58.5% of the precious metal was added to the alloy. The amount of silver and copper impurities was set at 8% and 33.5%, respectively. It was from the end of 1989 that the assay on gold "585" began to be popular on the territory of the USSR. As an addition to this alloy, next to the figures, the image of a girl in a kokoshnik was affixed to the items. The "predecessor" of this alloy - composition 583 - was accompanied by a stamp withstar.
Great for daily use
Gradually, products with this alloy began to be recognized and purchased not only in the countries of the former Soviet Union, but also abroad. Buyers were attracted not only by the reasonable price, but also by the amazing wear resistance of jewelry, on which the 585 test was affixed. The possibility of daily use of jewelry with this composition, their strength, shape stability - all these became the main criteria that buyers turned to before purchasing the next product. High-quality five hundred and eighty-fifth alloy confidently led among other analogues. Its demand has become indisputable proof that the 585 sample is a good replacement for the more expensive and not so durable 750 composition. Jewelry with the mark in question began to be called "Russian" gold.
Varieties
At present, more and more people have in their jewelry box jewelry made using the alloy in question. On the shelves of jewelry stores you can see a huge number of products on which there is a stigma "sample 585". Rings and bracelets, chains and pendants, pendants and earrings, a variety of sets - all sorts of conceivable and unimaginable items are made from an alloy that has already become familiar. In addition, the material is currently being used to make accessories, mobile phone covers, designer clothing, and more.
It would be useful to note thatin addition to the usual "Russian" gold with the composition in question, there is also white gold 585. The amount of valuable material in one gram of an alloy with this characteristic and its yellow "brother" is identical to each other. Only ligatures change - additionally added ingredients. So, if a product made of white gold has the radiance of steel, then this indicates the presence in the decoration of such an element as palladium. If the object pleases with a yellowish, barely visible shade, this indicates the use of nickel in its manufacture.
Cost of one gram
The abundance of all kinds of items made of precious metal cannot but please potential buyers. Even more pleasant is their cost: 585 assay, like all other samples of gold, is in close connection with the exchange rate for precious metals. Therefore, if the price per gram of pure material changes, the price of alloys with its use also changes. To date, the cost of gold without impurities has been established at the level of 1.320 thousand rubles per kilogram. Therefore, taking into account impurities, one gram of "Russian" gold will be sold for 800-830 rubles.
