Rainbow stone is made of fine grained quartz and various other minerals. The presence of other minerals lends attractive color to the stone. Depending on the percentage of constituent minerals the color varies in the form of brown, violet and sometimes reddish veins. It is because of the regular color variation that this stone has been named Rainbow. Like Khatu Teak, rainbow is also available in tiles in sawn finish since the same cannot be obtained in natural cleft surface. This sandstone owing to its soft nature does not take good polish but is used extensively in making garden ornaments.
