Looking for a unique, natural water feature that is sure to impress? The Aquascape Set of 3 Natural Mongolian Basalt Columns incorporates the sights and sounds of water to any environment, creating a beautiful water feature wherever they are installed. Each of the three columns is roughly 10-inches in diameter and the set includes stones of three varying heights at 24, 30, and 36-inches high. Mongolian Basalt Columns are mined from the mountains found between Russia and China, and each piece is handcrafted from natural stone. Once mined and shaped, the columns are then drilled to create a stunning water feature. No two columns are the same, providing each stone with unique qualities. Aquascape Natural Mongolian Basalt Columns can be paired with the Aquascape Large Aqua Basin, kink-free tubing and Ultra 2000 Pump for a complete setup. Aquascape is passionate about ponds, water features and gardening, providing unique products, designs, and features that stand above the competition.
