* Metamorphic rock: Marble is formed when limestone, a sedimentary rock, is subjected to heat and pressure deep within the Earth's crust. This process changes the composition and texture of the limestone, transforming it into marble.
* Crystalline rock: Marble is composed of interlocking crystals of calcite, a mineral that gives it its characteristic appearance.
* Natural stone: This term broadly describes any rock material that occurs naturally, and marble fits into this category.
* Building material: Due to its durability, beauty, and ability to be polished, marble has been used for centuries as a building material for everything from sculptures to floors to countertops.
* A symbol of luxury and elegance: Marble has long been associated with wealth and sophistication, making it a popular choice for high-end interiors.
So, depending on the context, marble could be considered any of these things.
