A fan asked if the silver ring they bought with the "925 silver" stamp on it is genuine silver. Muzi explains.
"925" silver has a silver content of 92.5% and a copper content of 7.5%. The majority of common silver jewelry is made of 925 silver. After polishing, 925 silver jewelry exhibits a beautiful metallic luster and possesses a certain degree of hardness, making it suitable for setting gemstones and creating mid- to high-end jewelry.
