Sylacauga marble, also commonly known as Alabama marble, is a marble that is found in a belt running through Talladega County, Alabama.[1] It is prized for its pure white color and its crystalline structure. The stone is named after the town of Sylacauga, Alabama, which is sometimes called "the Marble City".[2] Sylacauga marble has been called the "world's whitest".[3] Discovered in 1814, it has been mined for over 160 years, and is used for building, sculpture, and industry.[2] The Alabama Legislature passed Act 755 on September 12, 1969, which made this marble the state's official rock.[4]
