It is dark brown in colour with some lines that are light brown and grey in colour, and some abrasions that show up white on the surface. Its exterior surface is extremely textured with scratches and small marks, presumably from being hammer-dressed into shape. The fine lines or veins of the stalagmite are also visible on the surface of the maka tau. There are also 3-4 distinct black spots or stains on the flatter side of the stone. The maka tau was often used as a defending weapon in combat and if thrown correctly, could do real damage and even cause death.
