📜 Origin & History

Basalt Gray is one of the oldest colors of the Earth. Geological studies show that the oceanic crust is mainly composed of basalt; this dark gray volcanic rock covers approximately 70% of the Earth's seabed, making it the true底色 (base color) of the blue planet.

Ancient Roman architecture extensively used basalt as paving stone. The basalt slabs on the Appian Way, still坚固 (solid) after over two thousand years of wheel grinding, deeply linked Basalt Gray with the意象 (imagery) of eternity and resilience.

The Moai statues of Easter Island were carved from volcanic tuff, their gray-black hue being a variant of Basalt Gray. These silent megalithic figures stand guard facing inland, elevating Basalt Gray to a sacred color for mysterious religious ceremonies.

In contemporary landscape design, Basalt Gray stone is widely used in high-end commercial spaces. Architects like Kengo Kuma cut basalt into thin strips for building facades, using its porous texture and deep color to create modern rock walls interwoven with light and shadow.
