Rough diamonds are natural diamonds that have not yet been cut or polished. They are typically found in their raw form in nature, often in riverbeds or volcanic pipes. These unrefined stones can vary in color, size, and clarity, and their value is determined by factors such as carat weight and quality. Once extracted, rough diamonds are sold to gem dealers and manufacturers who transform them into finished gemstones through cutting and polishing. This process enhances their brilliance and value, making them suitable for use in jewelry. The journey from rough diamond to a sparkling gem is a crucial part of the diamond industry.
