Rosy Blue is one of the world's largest diamond jewellery companies and is the retail brand of “Orra”. The company was started 50 years ago; Dilip Mehta took over in 1973, as it was his family business and started expanding their business globally.
Today Rosy Blue has grown internationally and is operating two entities, one in India and the other that is active for rest of the world.
"Rosy Blue is a 'family corporation'. We have evolved differently from most diamond companies, which are managed by the core family. We have trained and groomed professionals to take over key job of trading diamonds which I don't think many other companies have done. This allowed us to scale up," says Russell Mehta.
