A chain is a piece of jewelry typically worn around the neck or wrist, consisting of connected links. Chains can be made from various metals, including gold, silver, platinum, or stainless steel, and vary in thickness, length, and design. They are versatile accessories, worn alone for a simple look or with pendants for added style. Chains are popular in both casual and formal settings, symbolizing elegance, sophistication, or personal style. They can also hold sentimental value when paired with meaningful charms or lockets.
