Vermont Verde Antique is a rich green serpentine stone quarried for over 100 years only in the Green Mountains of Vermont. Our serpentine is often referred to as “marble.” While it has the warmth and look of marble, it is actually harder and less porous than many types of granite and is in historic use throughout the world.
