Before you buy precious metal, you should study its external signs. The presence of a stamp is a must. This will mean that the piece of jewelry complies with the metal purity rating system. Standard<\/a> Several types of samples have been identified. In each one, the amount of pure gold is coded. Among the well-known designations (585, 750, etc.) you can find some not so common ones. <\/p>\n\n\n\n

There is a 555 hallmark, but not many people know what is encrypted in it. Theoretically, it could be a mark of purity of the precious metal, but not everything is so unambiguous. We need to find out what kind of alloys according to GOST, and whether the variant in question belongs to them.<\/p>\n\n\n\n

555 proof - what kind of metal<\/h2>\n\n\n\n

Among the existing types of samples, the 555 variety is absent. It is necessary to understand why then it occurs, and whether it is worth buying jewelry with such a designation. Along with this hallmark, another variety is used - hallmark 5S5. It does not meet the requirements for the marking of precious metals at all.<\/p>\n\n\n\n

\n

In fact, the hallmark 555, as well as its counterpart 5S5, are not included in the normative documentation that defines the order of hallmarking gold items. But that doesn't mean that the jewelry is worthless. You need to learn more about the properties of the metal that is assayed in this way.<\/p>\n<\/blockquote>\n\n\n\n

All items with more than 30% gold content must be branded accordingly. This is a numerical mark confirming that the jewelry includes some portion of the noble metal. <\/p>\n\n\n\n

The product may contain a stigma that does not meet the requirements of GOST, but its cost will be lower than that of certified products.<\/p>\n<\/blockquote>\n\n\n\n

555 gold hallmark: what information is the mark on gold, what does the gold hallmark mean?<\/h2>\n\n\n\n

If you're wondering what 5S5 is for a hallmark on a ring or other piece of jewelry, you need to find out what the mark is. The mark is of two kinds:<\/p>\n\n\n\n
