Silver jewelry rarely causes allergies, but some people might react to other metals mixed with silver. Pure silver (999) is too soft for jewelry, so most pieces are made from sterling silver (925), which contains 7.5% copper or other metals that could trigger reactions in sensitive individuals. If you notice redness, itching, or a rash where silver touches your skin, you might be reacting to these other metals rather than the silver itself. For sensitive skin, look for argentium silver or pieces with rhodium plating, which provide additional barriers against potential allergens.
