Former Tata Group chairman, Ratan Tata has made a personal investment in Bluestone, an online jewellery retailer, reports TOI. Ratan Tata, now chairman emeritus of Tata Sons, the holding company of the $100 billion steel-to-software Indian conglomerate, has subscribed to fresh shares of the three year-old e-commerce player which sells jewellery for women. 

As of now, the size of Tata's investment has not been disclosed. Last month, we reported that Tata made his first e-commerce investment when he picked up a small stake in Delhi-based Snapdeal by buying out an early investor. Interestingly, Tata group's brand Tanishq emerged as a billion dollar jewellery enterprise under his watch. 

"An investment by Ratan Tata who has been at the helm of India's most successful and respected conglomerate is a validation of our approach in building an innovative brand that is disrupting the jewellery market," said Gaurav Singh Kushwaha, Co-Founder, Bluestone.
