A necklace piece is a small object that is strung together with other objects to form a necklace. The two most common types of necklace pieces are beads and amulets. Beads are typically made of glass, stone, or metal and come in a variety of shapes and sizes. Amulets are usually made of metal or stone and often have a religious or spiritual significance. Both beads and amulets can be used to create beautiful and meaningful necklaces.
