Gold<\/a> It has been highly valued since ancient times, and its possession has always been considered a sign of success. It is impossible to work with the noble metal in its pure form; it always represents a certain alloy. The 500-point precious alloy is the most rare of all the others. <\/p>\n\n\n\n

\n

For its characteristic color it is dubbed \"red\", and the handling of products made of it is associated with certain difficulties.<\/p>\n<\/blockquote>\n\n\n\n

Gold of 500 proof, which is not found in the store<\/h2>\n\n\n\n

Products made of gold 500 samples<\/a>It is not to be found in Russian boutiques. To acquire such jewelry is possible only in private workshops, pawn shops, and at auctions. On the domestic market, this alloy has not become popular, but it is perfectly sold abroad.<\/p>\n\n\n\n

Composition, properties and unique labeling according to GOST<\/h2>\n\n\n\n

Gold is a noble metal, heavy and soft. Its natural beauty, coupled with its unique casting properties, has given it the greatest popularity among other jewelry.<\/p>\n\n\n\n

\n

For all its merits, this metal deforms very easily. This is why alloys with other precious metals are used in jewelry work.<\/p>\n<\/blockquote>\n\n\n\n

\"Red\" alloy is characterized by equal proportions of copper admixture, silver<\/a>, gold. It excludes the addition of other elements to the composition, such as palladium, which is often used for Alloy 585<\/a> \u0438 750 samples<\/a>. There is a reason why it is unpopular with jewelers: 500-gold is a porous material that is difficult to work.<\/p>\n\n\n\n

\n

The ratio of the alloy elements is as follows: 50% is gold, 43% is copper, and the remaining 7% is silver.<\/p>\n<\/blockquote>\n\n\n\n

Such gold has GOST 30649.99 and is designated as ZlSrM 500-100.<\/p>\n\n\n\n

The metal occurs in red-orange, dark yellow and light yellow colors. This difference is achieved by changing the proportions of impurities in the alloy.<\/p>\n\n\n\n

\n

The trademark red hue indicates that the alloy is dominated by copper - about 43%. Lighter items are characterized by a higher silver content - 33%.<\/p>\n<\/blockquote>\n\n\n\n

Matching 12 carats<\/h2>\n\n\n\n

With a golden carat<\/a> measures the proportion of gold in an alloy. It is similar to the metric assay and differs only in the numerical value.<\/p>\n\n\n\n

Gold of the 500 standard is equal to 12 carats according to the international karat<\/a> system or 48 spools. This means that the pure precious metal content is 50% for the item.<\/p>\n\n\n\n

\n

Important: Precious metal can be confused with gold-plated items. Pay attention to the branding. If next to the mark \"12K\" there are the letters \"G.K.\", then the jewelry is only gilded with this alloy.<\/p>\n<\/blockquote>\n\n\n\n

How to choose 500-proof gold abroad and distinguish fakes<\/h2>\n\n\n\n

Particular attention should be paid to jewelry purchased in Turkey, Egypt, and China. In these countries, there is no strict certification, so there is a risk of buying gold-plated jewelry under the guise of a high assay.<\/p>\n\n\n\n

Recommendations for the buyer:<\/p>\n\n\n\n

    \n
  1. Don't take the word of a salesman.<\/strong><\/li>\n\n\n\n
  2. Evaluate the item for defects and scratches. This appearance is only allowed for antique pieces. If you find any flaw on the jewelry, it could mean a fake or low-quality alloy.<\/strong><\/li>\n\n\n\n
  3. Carefully examine the inside of the item. There should be a branding that verifies the authenticity of the sample. Such branding looks like a tiny symbol, which will be unique to its country of manufacture. For example, a Russian manufacturer uses a branding depicting a woman in a headdress with her head turned to the left side.<\/strong><\/li>\n\n\n\n
  4. Study the product tag. If you are not familiar with the language, take the time to translate the tag with an Internet translator. It should contain information about the name, weight, proof, cost, composition, and manufacturer of the item.<\/strong><\/li>\n<\/ol>\n\n\n\n
    \n

    Following these precautions will allow you to choose a genuine precious metal.<\/p>\n<\/blockquote>\n\n\n\n
