How to distinguish the quality of sterling silver brooch? In order to identify the authenticity of Silver Jewelry, the method of sending it to the authority for inspection is the most accurate. But many people think that things worth hundreds of dollars are sent for inspection on a special trip, which is too troublesome. In fact, in addition to sending for inspection, consumers can also learn their own knowledge and use simple methods to identify the authenticity of silver jewelry.
3. The hardness of silver is low. Consumers can test the silver content by folding the silver ornaments lightly. If the silver ornaments are easy to bend and not easy to break, it means that the fineness is high, and vice versa.

If you can't judge from the color, you can also lightly throw it to the ground. The general standard silver jewelry has a dull and inelastic sound after landing. If it is made of copper, its sound is higher and sharper, and the rhyme is short and sharp.
2. Check the identification of silver jewelry. According to the standard of GB111887-2008 "Regulations on the Purity of Precious Metals in Jewellery and Nomenclature", silver jewelry sold on the market must be marked on the product to indicate the purity of silver, that is, the content of silver, expressed in thousandths.
Another reliable method is to use chemical detection method. Silver will change color in case of any acid, and even dissolve. If a drop of concentrated hydrochloric acid is dropped on the inside of the silver jewelry, it will immediately generate white moss-like silver chloride precipitation. However, this method will damage the silver jewelry to a certain extent. It is recommended to use it cautiously.
