Gold Jewelry<\/a> have been valued for several millennia. They are characterized by their yellow color and bright luster. Products made of this noble metal are presented in a wide range, differing in composition. In turn, the peculiarities of the components determine the properties and appearance of jewelry. One of the most common varieties is 750 proof. <\/p>\n\n\n\n

The alloy contains gold and a ligature. However, the ratio of the additives can vary, resulting in the metal taking on a shade of white to red. Different variants are popular in different countries. The price will vary accordingly.<\/p>\n\n\n\n

Assay 750 - what kind of metal, what it looks like, the concept of probability<\/h2>\n\n\n\n

Analytical methods are used to determine the quality of the metal, with their help<\/a>. This allows the consumer to determine which group a particular material belongs to. In addition, the evaluation of the alloy quality is given on the basis of the ratio of different components. <\/p>\n\n\n\n

\n

Accordingly, a sample is a result obtained as a result of applying one of the existing analytical methods (based on the determination of proportions, weight components).<\/p>\n<\/blockquote>\n\n\n\n

First of all, the 750th gold hallmark defines the amount of precious metal. Secondly, thanks to this designation, it is possible to find out the proportion of alloys in the composition. For example, 750 parts of gold per 1,000 parts by weight. The remainder is in the form of additives. The alloy is characterized by its yellow color and low Mohs hardness, which makes it easy to polish.<\/p>\n\n\n\n

The assay makes it possible to know the amount of precious metal relative to the entire mass of the alloy. It uses a different principle of counting gold fractions, which determines what the alloy's designation will be. Since the concept of assaying was introduced and the first method of carrying out this procedure was developed, different systems have been used right up to the present day:<\/p>\n\n\n\n
