Basalt
Basalt explained in an easy to understand way:
Imagine trying to choose the right couch for your living room, only to find that the one you like is heavy, dark-colored, and incredibly durable, seemingly absorbing everything around it. This scenario is similar to basalt, a dark, dense igneous rock that forms from rapidly cooling lava, making it both strong and tough. Just like your choice of couch, basalt is defined by its dense, robust nature and dark appearance, which results from its composition and formation process, much like the fabric and design choices that define your furniture.
