Simply mind-boggling
Vallabhbhai S Patel set up Kiran Gems in 1985 and saw it grow into India's largest exporter of diamonds.
Kiran Gems' manufacturing units are based out of India's diamond hub Surat and out of Ahmedabad and provide employment to over 30000 people who process a mind-boggling 5.7 million carats of rough diamonds annually to generate over 1.6 million carats of polished diamonds.
His labours have seen Patel's net worth zoom to $590 million.
