Our Peruvian jewelry sets are made from an alloy of zinc, iron, copper and nickel (Alpaca Silver). This unique jewelry has properties similar to stainless steel and will not tarnish or rust. Peruvian jewelry, unlike some silver and stainless steel jewelry, does not need a coating to make it shine and This unique jewelry quality makes Peruvian jewelry (made with Alpaca silver) hypoallergenic and much more comfortable to wear, especially for anyone with allergy problems to some of the coatings. Please note that this unique jewelry, alpaca silver jewelry, is not real silver. Never use silver dipping liquids on Peruvian jewelry, as they will harm your unique jewelry. With any jewelry you should never spray perfume directly on it, as it will discolor and may cause damage to your handcrafted unique jewelry pieces.
