Limestone vs. Marble — What's the Difference?
By Tayyaba Rehman & Fiza Rafique — Updated on March 15, 2024
Limestone is a sedimentary rock composed mainly of calcite, formed from marine organisms, while marble is a metamorphic rock resulting from the metamorphism of limestone, characterized by its veined appearance.

Key Differences
Limestone is a sedimentary rock that forms at the bottom of oceans and seas through the accumulation of shells, bones, and other calcium-rich materials. On the other hand, marble is a metamorphic rock that originates from limestone or dolomite through a process of high pressure and temperature within the Earth's crust. This metamorphism causes the calcite in the limestone to recrystallize, forming marble's distinctive veined and patterned appearance.
The physical properties of limestone and marble differ significantly due to their formation processes. Limestone is typically softer and more porous compared to marble, which is harder and denser. This makes marble a preferred material for sculptures and building decoration, as it can be polished to a high shine, showcasing its unique veining and colors. While limestone also finds use in similar applications, its porosity makes it less durable under certain conditions, although it is still valued for its natural, rustic appearance in architectural projects.
In terms of applications, limestone is more versatile, used in the production of cement, as aggregate in concrete and asphalt, and in the manufacture of glass and steel. Marble, with its aesthetic appeal, is predominantly used in the art and architecture sector, for countertops, flooring, and as an ornamental stone. The choice between limestone and marble for a particular use often depends on the desired aesthetic effect and the physical properties required for the application.
The environmental impact of quarrying and processing these rocks is another aspect where limestone and marble differ. Limestone quarrying is generally considered to have a less pronounced environmental impact compared to marble quarrying, which often involves more intensive processes to extract and polish the stone. However, both industries are working towards more sustainable practices to minimize their environmental footprint.
Despite their differences, both limestone and marble have played significant roles in human history and culture, from ancient architecture to modern-day construction and art. Their beauty, versatility, and utility continue to make them valuable natural resources.
