Sterling silver is not necessarily hypoallergenic. Sterling silver is an alloy of silver and other metals, typically copper, and it may also contain trace amounts of other elements. Some people may be allergic to these metals or further details and experience a skin reaction when wearing sterling silver jewelry. However, sterling silver is generally considered less allergenic than different types of jewelry, such as nickel or gold, and many people can wear sterling silver jewelry without any problems. If you have sensitive skin or are unsure about your ability to wear sterling silver jewelry, you can test a small area of your skin before wearing it more extensively.
