The marking "975" on a ring indicates that the metal is 97.5% pure, which means it is made of 975 parts per thousand of pure metal, typically silver. This designation is often used to signify high-quality sterling silver, as traditional sterling silver is 92.5% pure (marked as "925"). The higher purity level suggests a more valuable and premium product. Always verify authenticity through reputable sources when purchasing jewelry.
