📜 Origin & History

Granite Gray is the iconic color of the Earth's continental crust. This plutonic rock slowly cools and crystallizes several kilometers below the surface, forming its unique blue-gray hue. The core rock masses of major mountain ranges worldwide are composed of granite; it is the true color of the Earth's skeleton.

Ancient Egyptians began quarrying granite as early as 4,500 years ago. The giant unfinished obelisk left in the Aswan quarry demonstrates the remarkable skill of ancient Egyptian craftsmen in mastering this hard, dark gray stone. Granite Gray became a symbol of the Pharaohs' immortal power.

In the 19th century, Aberdeen, Scotland, became world-famous for its gray granite architecture. The locally sourced blue-gray granite was used to build London's Waterloo Bridge and the pedestal of the British Museum, earning Aberdeen the title 'The Granite City.'

In contemporary architecture, Granite Gray is widely used for the curtain walls and pedestals of skyscrapers. I.M. Pei's Bank of China Tower in Hong Kong paved its entrance plaza with Granite Gray stone, using the heavy color of the earth to anchor this soaring glass and steel skyscraper.
