India imported 163.11 million carats of rough diamonds worth US$ 16.34 billion and exported 36.46 million carats of polished diamonds valued at US$ 20.23 billion in 2014. The country exported gems and jewelry worth US$ 36.04 billion in 2014. India has signed a Memorandum of Understanding (MoU) with Russia to source data on diamond trade between the two countries. India is the top global processor of diamonds, while Russia is the largest rough diamond producer. The Government of India is planning to establish a special zone with tax benefits for diamond import and trading in Mumbai, in an effort to develop the city as a rival to Antwerp and Dubai, which are currently the top trading hubs for diamond.
