What stones are beautiful examples of metamorphic stones?

The correct choice highlights marble and slate as beautiful examples of metamorphic stones. Metamorphic rocks are formed under high pressure and temperature conditions, leading to the transformation of existing rock types.

Marble, for instance, originates from limestone and is known for its beautiful veining and aesthetic appeal, making it a popular choice in both classic and contemporary interior design. Its durability and luxurious appearance make it suitable for various applications, such as countertops, flooring, and decorative elements.

Slate also exemplifies the metamorphic process, originating from shale. Its characteristic layered structure and range of colors contribute to a unique visual impact, making it ideal for flooring, roofing, and wall coverings. Its ability to split into thin layers allows for diverse design options, appealing to many interior design aesthetics.

In contrast, granite and sandstone are classified as igneous and sedimentary rocks, respectively, thus not fitting the criteria for metamorphic stones. Limestone and travertine, while beautiful, are sedimentary rocks that undergo different formation processes. Lastly, onyx and quartz are types of sedimentary and crystalline stones that do not represent the metamorphic category.
