The "520" stamped on a silver ring typically indicates that the ring is made of a silver alloy that contains 52% silver content, which is less than the standard sterling silver composition of 92.5% silver. This lower silver content may affect the quality and value of the ring. It's important to verify the authenticity and quality of the metal, as jewelry marked with lower silver content may not hold the same value as higher-grade silver.
