Origin of Natural Stones

In India, quarries for exported natural stones are concentrated mainly in two regions:

  • North India: States Rajasthan, Madhya Pradesh, and Uttar Pradesh
  • South India: States Andhra Pradesh, Karnataka, and Tamil Nadu

There are about 100 provenances where natural stones for the export are mined. This are small areas (e.g. a hill) where the same type of natural stones can be found. The mining can be done by different lessees or owners. One provenance can be subdivided in about up to 12 mining sections.

In China, quarries for exported natural stones are concentrated mainly in two regions, too:

  • South China, mainly the state Fujian;
    Granite from Fujian is classified with G600er numbers (e.g. G602)
  • North China, mainly the state Shandong;
    Granite from Shandong is classified with G300er numbers (e.g. G341)
