Fashion jewelry can stain if it comes into contact with certain substances such as water, sweat, perfume, lotion, or other chemicals. The metal in fashion jewelry can react with these substances and cause discoloration or staining. To prevent staining, it's important to remove fashion jewelry before swimming, exercising, or applying lotions or perfumes. Additionally, storing fashion jewelry in a dry and clean environment can help prevent staining. **
