Although durable, stones like sandstone, granite, and marble can break easily under certain conditions.
Marble: A metamorphic rock formed from the recrystallization of limestone. It is characterized by its smooth texture, natural sheen, and wide range of colors, from pure white to shades of green, red, and black with intricate veining.Granite: An igneous plutonic rock mainly composed of quartz, feldspar, and mica, known for its high durability and strength. Its speckled appearance and variety of colors make it ideal for both exterior and interior construction. Sandstone: A sedimentary rock primarily made up of cemented sand grains. It is porous, with a rough texture and a color range from beige to reddish hues, ideal for architectural and decorative works due to its natural look and ease of carving.
