Genuine diamonds are natural gemstones formed deep within the Earth's mantle under high pressure and temperature over millions of years. They are composed of carbon atoms arranged in a crystal structure, which gives them their exceptional hardness and brilliance. Genuine diamonds are often used in jewelry, particularly in engagement rings, due to their beauty and durability. To determine the quality of a genuine diamond, the Four Cs are considered: carat weight, cut, color, and clarity. These factors influence a diamond's value and appearance. Unlike synthetic diamonds, which are created in laboratories, genuine diamonds are mined from the Earth, making them unique and sought after.
