The hallmark "SY" indicates that a piece of jewelry or metal is made of sterling silver, which is composed of 92.5% silver and 7.5% other metals, typically copper. This mark is often found on silver items to ensure authenticity and quality. In some contexts, it can also represent a specific manufacturer or designer's mark.
"I-sy" means "listen" in Welsh. It is a command form of the verb "gwrando," which means "to listen."
