Rajasthan is the mainstay of the Indian stone industry and has over 90 per cent of the country's marble, sandstone and flaggy limestone deposits along with a major share of granite and slate deposits spread over the entire state.

Rajasthan alone accounts for 1,100 million tons of the total known Indian resources of 1200 million tons (91 per cent of India's deposits) and 95 per cent of India's marble production. With a production of 3.44 million tons in 1997-98 and about 3658 marble mining leases, 1,100 marble processing units and 50 automatic tiling plants with a marble slab processing capacity of 1,000 million sq. ft. per annum and marble tiling capacity of 300 million sq. ft. per annum, the marble industry in Rajasthan is phenomenal.

Granite reserves are estimated at 1128 million cubic metres with about 653 granite-mining leases resulting in a production of 52,020 tons in 1997-98. The  granite industry has a slab processing capacity of 15 million sq. ft. per
annum and a granite tiling capacity of 50 million sq. ft. per annum.

The vast deposits of sandstone accounting for a production of 4.91 million tons in 1997-98 from 1847 mining leases; flaggy limestone (Kotahstone) deposits with an estimated production of 2.10 million tons in 1997-98; huge slate deposits accounting  for a production of 8,000 tons in 1997-98 from 32 slate mining leases,  the state employs about 10,00,000 people.

The Rajasthan stone industry is poised for a foray into the International stone market with its wide variety of stones and a dynamic entrepreneurial base. The industrial infrastructure in Rajasthan compares favourably with the best in the country. Industrial areas developed by the Rajasthan State Industrial Development Corporation Ltd. (RIICO) are spread over the whole state and have catalyzed an industrial revolution in the state.

The state has a well developed road and rail network well connected with the rest of India. Rajasthan also has a dry port with Inland container depots for easy exports.

The Government of Rajasthan is stressing the need  to develop the  stone sector in Rajasthan and has announced a wide variety of incentives and concessions to the stone industry. The state has brought forward in its New Industrial Policy, Mineral Policy, Marble Policy and Granite Policy.

Marble
The marble industry in Rajasthan is modern and very well developed with mechanized quarries, tiling plants, gangsaws etc. However, most of the production is consumed within India and international exposure is limited and needs to be exploited.

Colors and patterns like Snow white, Creamish white, White with grayish/black bands and Wavy patterns, pink, pink with bluish bands, green, yellow, black, multi-color are mined in districts of Nagaur, Udaipur, Banswara, Jaipur, Sirohi, Bhilwara, Ajmer, Bundi, Pali, Dungarpur, Chittorgarh, Jaisalmer, Sikar, Rajsamand, Alwar. Whereas, on the export list are Snow white - fine grained, green and pink.

Granite
In districts of Barmer, Jalore, Pali, Sirohi, Alwar, Jaipur, Jhunjhunu, Tonk, Ajmer, Bhilwara, Sikar, and Udaipur, the geological reserves of high quality granite with hardness ranging from 6-7 on Moh's scale is around 1128 million Cu. M. Production of granite in 1997-98 was 52,020 tonnes with processing capacity of 1.5 million sq. m. of slabs and 5.0 million sq. m. of tiles.
