What is sterling silver?
What does that mean? To make silver tougher and more durable, silver is often alloyed with other metals, which results in different types of silver. Based on the content of the other metals mixed in to the silver, silver is usually identified by hallmarks. A hallmark is generally an indication of metal content, purity and quality that is marked on individual pieces. For example, sterling silver, by definition is a mix of 92.5% silver and 7.5% copper alloy. Therefore, pieces using sterling silver are tagged or engraved with 925 Silver or SS.
