583 gold sample - the memory of the Soviet Union

Until recently one of the most popular in jewelry was 583 gold sample. Today, the market can find a variety of jewelry. How could understand them? It is no secret that impart articles of the precious metal higher wear resistance and hardness produce alloys with other chemical elements. These additives are added to the gold, called a ligature. The best of them are considered to be copper and silver. They improve all the characteristics of the alloy. Products made of pure gold are extremely rare, because it is easily deformed, quickly scratched, and very soft.

sample systems

In today's world there are four systems that determine the precious metal samples. The most commonly used metric and carat. What is the difference between them? In the CIS countries use the metric system. It purest gold content is determined by the amount (in grams) in 1 kg of the precious alloy. The standard of the USSR was 583 gold sample. Products made of it were the most common. Now adopted a new metric system, in which a sample is not. Please be aware that 583 gold sample indicates that 1 kg 583 g of alloy - pure gold and 417 g - ligature. In the modern metric system there are some samples: 375, 585, 500, 950, 750, 999. A sample of gold - a stigma that should be placed on any product of this precious metal. Without it, you should never buy a product because it may be a fake. carat system

In Europe and in the United States use carat sampling system. The amount of pure gold in it is a component of an alloy of 24 parts. All this metal alloys equate to 24. For example, a 14K sample indicates that it contains 14 parts of pure gold. In such a system is the alloys 9, 10, 18, 14, 24 carat. When you divide 14 by 24 turns 0, 58333. Although it is close to the 583 trial, but a little more of her. Therefore, to bring the Russian metric system to the carat, 583 gold sample was changed to 585.

types of gold

In different countries, some types of gold are very popular compared to the other. For example, in the CIS countries the greatest demand is for the precious alloy with a reddish tinge, and in the Americas and Europe - with yellow. Gold gives a reddish hue copper master alloy, and the yellowish - silver. Absolutely pure precious metal has a bright yellow color. Adding silver alloy leaves it substantially the same yellow. If the product of pure precious metal is heated, gold is a little oxidized, thus become a magenta tint. In the old days such gold has always been called "Red." Only pure precious metal is converted by heating in pure gold. In the presence of the slightest impurities, this effect is lost. Luster of pure gold is very pure and clear, and alloy 585 slightly turbid, and paint it more faded. White gold is an alloy of gold with special ligature. It acts as palladium or nickel. They give fusion of different shades of white. Palladium ligature gives white and steel, and nickel - slightly yellowish tint. Rare white gold with rhodium differs cold blue.
