Diamond jewelry refers to decorative items made from diamonds, which are precious gemstones known for their brilliance and hardness. Common types of diamond jewelry include rings, necklaces, earrings, and bracelets. These pieces are often set in metals like gold or platinum, enhancing their beauty and value. Diamonds are graded based on the Four Cs: cut, color, clarity, and carat weight. The cut affects how well the diamond reflects light, while color and clarity determine its overall appearance. Due to their rarity and desirability, diamond jewelry is often considered a symbol of luxury and is frequently used in engagement rings and special occasion gifts.
