This 3-tier waterfalls fountain is made from rajah slate from India. It is meticulously carved, chiseled, and smoothed by hand. The water flows out from the pool in the top slate tier, tumbles into the larger pool in the middle tier, and then into the largest pool in the bottom slate base, which sits on a beautiful water-proofed terra cotta bowl (where the pump sits). The 3-tier waterfall sounds are absolutely beautiful, relaxing and soothing.
