The company
Rosy Blue (India) Pvt. Ltd. — Mumbai
As Managing Director, Russell Mehta is responsible for the Rosy Blue group’s companies in India. The principal work of four decades has been to convert a family-managed diamond business into a professionally run company — delegated authority, systems that outlast individuals, and governance that a partner or a bank can read.
Rosy Blue trades rough diamonds and manufactures polished stones, alongside precious and semi-precious gems and jewellery. It has been headquartered in Antwerp since the 1970s and is a certified De Beers sightholder. The wider group’s interests extend into retail, media, real estate, financial services and clean energy.
- Founded 1960 as B. Arunkumar & Co., Mumbai
