- Columns various width and heights
Basalt is a dense igneous volcanic rock formed from hardened lava. Columns are found in areas where lava cooled quickly, resulting in contraction and horizontal fracturing. These columns have attractive 5 and 6 sided shapes with a thin outside layer ranging from beige to red and black, often displaying an array of color. The inside of basalt is jet black and polishes up to a rich luster.
