Shell necklaces are decorative accessories made from various types of shells, often collected from beaches. These necklaces can feature a single shell or multiple shells strung together, creating unique designs. They are popular in many cultures and are often associated with coastal regions. The use of shell necklaces dates back thousands of years, with evidence found in archaeological sites. Many indigenous peoples, such as the Maori of New Zealand and the Native Americans, have traditionally crafted shell jewelry for both decorative and ceremonial purposes. Today, shell necklaces are commonly worn as fashion items or souvenirs from beach vacations.
