Jewelry refers to decorative items that are worn for personal adornment, such as necklaces, bracelets, earrings, rings, and brooches. Jewelry is often made from precious metals like gold, silver, and platinum, as well as precious and semi-precious gemstones like diamonds, rubies, sapphires, and emeralds. However, jewelry can also be made from other materials like beads, glass, wood, and plastic.
