Granite is the most durable natural material that is available in substantial quantity. It is more resistant to deterioration from weather and from chemicals than any other plentiful material. Those huge towers supporting the Brooklyn Bridge? Granite. Cobblestones? Granite.
You can find a granite memorial stone at a cemetery or some stone engraving companies. They are very commonly used and have a bit more gloss than other types of stone.

The National Cemetery at Gettysburg was designed by the landscape architect William Saunders. *The first monument of any type to be placed at Gettysburg was the Soldiers National Monument in the National Cemetery. It was designed by the Batterson-Canfield Company and sculpted by Randolph Rogers. The cornerstone was laid on July 4, 1865, and the full monument dedicated on July 1, 1869. The white Westerly granite pedestal supports a shaft and marble statue entitled "Genius of Liberty."
