Naveen Kumar Singh was found dead at his home in Pune, Maharashtra, on Friday, the local police said.
His family had reportedly filed a complaint on Friday after his mother found him unconscious at their residence, which he shared with his brother and younger sister.
Singh’s body was taken to the Pune Medical College Hospital where he was pronounced dead.
The police had not yet confirmed the cause of death.
The company that Singh worked for is called Indus Diamond, and its website says its goal is to bring diamonds to the world “from the land of diamonds”.
In 2016, Indus launched a pilot program in India to bring Indian diamonds to other countries.
The company said it will bring more than 300 million diamonds to India by the end of 2020.
Indus was founded in 2014 and has produced jewelry in the country since then.
Its website said Singh was a partner of Indus Jewelry.
“He was an ardent supporter of Indusa and his work and dedication was well-deserved,” the company said in a statement on Sunday.
