Marble is a metamorphic rock formed from limestone, primarily composed of calcium carbonate with a crystalline structure. It features unique patterns and colors due to the presence of other minerals. Used for thousands of years in architecture and art, marble remains popular for flooring, countertops, and décor. While durable and heat-resistant, it requires regular maintenance due to its porous nature, making it susceptible to staining. Despite this, marble continues to be cherished for its timeless beauty and versatility.
