How does the weight of granite compare to marble?

Granite and marble are two of the most popular natural stones used in construction and design, but they differ significantly in weight due to their unique compositions. Granite is generally heavier than marble, with an average density of about 2.65 grams per cubic centimeter (g/cm³). In contrast, marble has a lower density, averaging around 2.71 g/cm³, though this can vary depending on the specific type and mineral content.

The weight difference stems from their formation processes. Granite is an igneous rock formed from cooled magma, making it denser and more durable. Marble, on the other hand, is a metamorphic rock derived from limestone, which is less dense and more porous.

This weight disparity has practical implications. Granite's heavier weight makes it ideal for high-traffic areas and outdoor applications, while marble's lighter weight is often preferred for indoor decorative elements like countertops and sculptures. Understanding these differences helps in selecting the right material for specific projects, ensuring both functionality and aesthetic appeal.
