Surat, previously known as Surya, is a city in the Indian state of Gujarat. It is also administrative capital of the Surat district. The city is located 306 km south of the state capital, Gandhinagar, and is situated on the left bank of the Tapti River (Tapi), the center being around 22 km (14 mi) from the river's mouth.
Surat is Gujarat's second largest city and India's eighth most populated city (in terms of population living in the Municipal Corporation area), with a population of 4.5 million. The city registered an annualized GDP growth rate of 11.5 per cent over the seven fiscal years between 2001 and 2008.
A moat divides the older parts of the city, with its narrow streets and handsome historical houses, from the newer suburbs. The city is largely recognized for its textile and diamond businesses. It is also known as the diamond capital of the world and the textile capital/Manchester textile city of India, a distinction it took over from Ahmedabad. 92% of the world's diamonds are cut and polished in Surat.
