Polished stone refers to natural stones that have been smoothed and shiny through a process of grinding and polishing. This technique enhances the stone's appearance, revealing its colors and patterns, making it popular for decorative items, jewelry, and countertops. Common types of polished stones include granite, marble, and quartz. The polishing process typically involves using abrasives and specialized tools to achieve a high-gloss finish. Polished stones are often used in architecture and design due to their aesthetic appeal and durability. They are also valued in gemology for their beauty and are often cut into various shapes for use in jewelry.
