The quality and silver content of all silver ornaments and gifts must be accurately marked. The United States Federal Trade Commission (FTC) has formulated a set of stamps and identification marks indicating the silver content, which should be observed when purchasing. Silver jewelry with a pure silver content of at least 92.5% can be called pure silver. Sometimes, the numbers ".925", "9.2.5" and "925" are printed on the silver ornaments, which are exact identification marks and can ensure that the genuine sterling silver jewelry with standard components is purchased. When purchasing, you should check the manufacturer's trademark or the inspection mark of London Gold Trading Company to prove the purity of gold and silver. Professional jewelers will explain these marks in more detail. The price of silver ornaments and silver gifts is determined according to the content of precious metals, structural design and craftsmanship. Pay special attention to its fasteners when buying to see if they are easy to fasten and secure. When buying a silver chain, lay it flat and see if the links are kinked or bent. When buying silver-plated jewelry, check whether the coating thickness and coating coverage are comprehensive.
According to the relevant regulations of the state, the imprint of gold and silver jewelry should include the name of the material and the amount of gold (silver, platinum). If the weight of a single piece of gold and silver jewelry is less than 0.5 g or it is really difficult to mark, the content of the imprint can be exempted. A gold and silver ornament is made of two or three precious metals: gold, silver and platinum. The name of the precious metal material used and the content of gold (silver and platinum) should be used as the imprint content.
