A necklace part is an item that is used to make a necklace. The most common necklace parts are beads, pearls, clasps, and pearlets. Beads are small, round objects that are strung together to form a necklace. Pearls are smooth, round objects that are often used as a centerpiece for a necklace. Clasps are small metal pieces that are used to fasten the necklace together. Pearlets are small, round objects that are similar to pearls but are usually less expensive.
