A pearl necklace is a piece of jewelry made from pearls, which are organic gemstones formed inside mollusks, such as oysters and mussels. These necklaces can vary in length, style, and the type of pearls used, including natural, cultured, or freshwater pearls. They are often associated with elegance and sophistication, making them popular for formal occasions. Pearl necklaces can be strung together in various designs, such as single strands, multi-strand, or with added embellishments like gold or silver clasps. They are often gifted for special occasions, such as weddings or anniversaries, and are considered timeless accessories in fashion, often linked to iconic figures like Audrey Hepburn.
