Granite
 

The term "Granite" is derived from latin word "Granum" meaning "grain" because of its granular nature. Rajasthan is well known since time immemorial for its building and dimensional stones like Marble, Sandstone, Limestone, Slate etc. Recently granite has also been added to this list. Granite occupies a prominent place among dimensional stones on account of its hardness, durability, capability to take mirror polish and fascinating colours. As such the use of granite has increased many fold as dimensional and decorative stone all over the world and this has created a good export market for Indian Granite.

Granite has a 95% share in India's dimensional stone export. The export of high value added items like tiles, polished slabs and monument stones has increased by over 50% average growth rate per year.

Status of Granite Industries

A large number of granite based processing units are operating in Rajasthan including many processing units of large and imported Gangsaws. Some of these are totally export oriented units. A number of tiny/small tiling plants are also in operation. Units are mainly located at Jalore, Sikar, Abu Road, Alwar, Jhnjhunu, Jaipur, Banswara, Shahpura, Ajmer, Chittaurgarh, Udaipur, Badnor, Devgarh, Raipur, Pali, Jodhpur etc.

Commercial expolitation of granite in India is confined largely to Andhra Pradesh, Karnataka, Rajasthan, Tamilnadu, Orrisa, M.P., Bihar and Gujrat. India is second largest exporter of granite blocks and finished slabs and tiles.
