It's best to avoid getting your pearls wet as moisture can seep inside and cause damage over time, including discoloration, cracks, pits, or loss of luster. After wearing, gently wipe pearls with a soft cloth to remove dirt, oils, and perfume. When showering, take your pearls off beforehand or secure them up in your hair, away from water exposure. Although brief water contact won't immediately harm pearls, prolonged soaking or long showers can diminish their quality and appearance.
