Indian granite industry is in peril in the absence of a uniform policy from the State Governments, despite the thrust given by liberalization policies of the Union Government in the last two years. Compared to the remarkable progress in the field during the last three years, the absence of matching policies by State Governments had put granite quarry owners and others involved in the industry on the verge of collapse in the international market. The policies differed from state to state, had created problems as far as loyalty, dead rent and duration of lease were concerned.

The granite produced in India does not match with the quality of international level.
