When buying any piece of jewelry, we always see small numbers and various letters and symbols on it. Not everyone knows what the brand on jewelry means. This definition was introduced into the jewelry business when it became necessary to track the consumption of precious metals, as well as their content in alloys. From the sample, you can determine what proportion of the precious metal is in the alloy, and with the help of other graphic symbols, you can find out the country of origin and other information. If you know what samples of precious alloys are, you can easily determine the quality of any product from the jewelry industry.
Branding of jewelry and everything you need to know about it
The stigma is certainly put on all jewelry and objects made of precious metals and their alloys. This includes models with inserts of precious and colored stones. The stigma is also necessarily placed on premium products. The sample is not left on precious metal nuggets that are used as jewelry (for example, pendants or inserts). There is also no need for hallmarks on gold/silver leaf, and also on precious framing used on dishes, vases and caskets.
Absolutely all hallmarks of precious metal alloys are regulated: they are controlled by special government agencies. Each individual piece of jewelry is subject to control. If the test is successfully passed and the model fully meets all international requirements, it is stamped with numbers, which indicates the sample, as well as graphic signs. But if there is no such mark on the product, then its quality is rather doubtful.
According to international standards, hallmarking of jewelry should in no way affect the design. Depending on the type of decoration, the stigma has a different location. For example, on rings, the brand is located on the inside of the jewelry. For pendants, a different location of the hallmark is characteristic: it is located near the ringlet — fasteners for suspension. The sample can also be found on the clasp of a chain, bracelet and earrings.
Stamp variations on different models
There are different types of hallmarks on jewelry. It all depends on the manufacturer of the jewelry (including its geographical location), as well as on the date of manufacture. Until the nineteenth century, spool and carat assay systems were popular in the world. Now this system is facilitated and standardized for almost all countries of the world. The most popular is the metric system (it uses 3‑digit numbers).
Stamp on jewelry — transcript:
- geometric designation — the type of metal (for gold, a rectangular mark is used, for silver models — a rectangular mark with rounded ends, and for platinum — an eight-point mark);
- digital designation is a decoding of the quality level of the metal;
- the letters indicate the region in which the composition of the metal was verified, and the sample was also taken;
- the graphic symbol in the hallmark indicates the place of manufacture of the jewelry.
The most popular metals among jewelry manufacturers are gold and silver. Samples on them contain numbers that indicate the proportion of pure metal content in them. For gold, 999 fineness is considered to be the standard — such jewelry contains 99.9% of gold. Also, for gold jewelry, 958, 750, 585, 500 and 375 samples are used. Silver models can contain 999, 960, 925, 875, 830 and 800 fineness.
