Sparkling gemstones are precious or semi-precious stones that exhibit brilliance and shine due to their unique internal structure and the way they reflect light. Common examples include diamonds, sapphires, and emeralds. The sparkle of these gemstones is enhanced through a process called cutting, which shapes the stone to maximize its light-reflecting properties. The value of sparkling gemstones is determined by several factors, including their color, clarity, cut, and carat weight, often referred to as the Four Cs. These factors contribute to the overall beauty and desirability of the gemstones, making them popular choices for jewelry and decorative items.
