Jewels are precious or semi-precious stones that are often cut and polished to enhance their beauty. Common examples include diamonds, rubies, sapphires, and emeralds. These stones are valued for their rarity, color, clarity, and size, making them popular choices for jewelry and decorative items. In addition to natural gemstones, there are also synthetic jewels created in laboratories. These man-made stones can mimic the appearance of natural gems and are often more affordable. Jewels have been used throughout history in various cultures for adornment, status, and even as symbols of power.
