It seems there's a little confusion in your description. Statuario marble is not an igneous rock, but rather a type of metamorphic rock, specifically a high-quality white marble. This marble is indeed quarried in Italy, particularly popular from the Carrara region. Statuario stands out for its uniform backgrounds and distinctive gray or gold veining. It's favored globally for its aesthetic qualities, making it a top choice for luxurious sculptural works, architectural elements, interior decorations, and stylish surface installations. Your description aptly captures its widespread use in architecture and design due to its stunning natural appearance and functional properties.
