Overview

Rosy Blue is a privately owned Indian-Belgian business group best known for its activities in the international diamond and gemstone trade. The company operates across the value chain, dealing in rough diamonds and precious commodities while also manufacturing and distributing polished diamonds, precious and semi-precious gemstones, and jewellery. Its business has historically been connected with major diamond-trading centres, with Antwerp serving as an important base after the company expanded internationally in the 1970s. The company was established in 1960 by Arunkumar Mehta and his uncle Bhanuchandra Bhansali. From its Indian origins, Rosy Blue developed an international operating footprint that includes offices or operations in Belgium, Israel, Hong Kong, Japan, the United States, China and the United Arab Emirates. Reference material describes the group as having 12 offices across seven countries and as one of the larger diamond and gemstone traders worldwide. Rosy Blue is also identified as a De Beers sightholder, linking it to the organized distribution system for rough diamonds supplied through De Beers. Although diamonds and jewellery remain its defining activities, Rosy Blue has interests beyond the core gems business. The company has been associated with clean energy, media, real estate, financial services and retail. These activities give it the profile of a diversified private group rather than a narrowly focused jewellery label. Publicly available reference material does not provide a complete breakdown of the ownership structure, revenue mix or the geographic contribution of each business. Rosy Blue joined the Responsible Jewellery Council as a founding and certified member in 2005, and became a signatory to the United Nations Global Compact in 2008. These steps placed the group within international initiatives addressing responsible business conduct and supply-chain standards in the jewellery sector. At the same time, the company was named in reporting connected with the Panama Papers and Paradise Papers in 2017. The available reference identifies Rosy Blue as an entity associated with transfers to offshore jurisdictions in the context of tax avoidance; it does not, by itself, establish the outcome of any criminal prosecution or regulatory finding. Russell Mehta is identified as Rosy Blue's chairman and managing director. The business remains privately owned and active, with its public identity centred on international diamond trading, gem processing, jewellery manufacturing and distribution, supported by a wider portfolio of investments.

History

Rosy Blue was founded in 1960 by Arunkumar Mehta and his uncle Bhanuchandra Bhansali. The company developed as an India-linked diamond and gemstone enterprise and expanded beyond its initial base as international trade in precious stones became increasingly organized around specialist centres. During the 1970s, Rosy Blue established its headquarters in Antwerp, Belgium, and extended its operations into other major diamond markets. The group's core activities grew to cover both upstream and downstream parts of the gems and jewellery value chain. It trades in rough diamonds and other precious commodities, manufactures and distributes polished diamonds, and handles precious and semi-precious gemstones and jewellery. Rosy Blue is also described as a De Beers sightholder, giving it a role in the structured distribution of rough diamonds through the De Beers system. Reference material characterizes it as one of the world's larger diamond and gemstone traders. Over time, the group developed an international network reported as 12 offices in seven countries: Belgium, Israel, Hong Kong, Japan, the United States, China and the United Arab Emirates. In addition to its core gems activities, Rosy Blue has interests in clean energy, media, real estate, financial services and retail. This diversification makes the organization a broader private business group rather than only a diamond manufacturer or consumer jewellery label. Rosy Blue's public record also includes participation in industry and international responsibility initiatives. In 2005 it became a founding and certified member of the Responsible Jewellery Council. In 2008 it signed the United Nations Global Compact. Both affiliations are relevant to the jewellery industry's efforts to address supply-chain responsibility, ethical conduct and sustainability, although the available material does not provide detailed audit results or a full account of the company's implementation. In 2017, the company was named in reporting associated with both the Panama Papers and Paradise Papers. The reference material describes an entity linked to Rosy Blue as having transferred money to offshore jurisdictions to avoid taxes in the relevant country. The supplied sources do not establish whether the reporting led to a conviction, settlement or other final legal outcome, so the episode should be treated as a reported controversy rather than a confirmed criminal judgment. Russell Mehta is identified as the current chairman and managing director. Rosy Blue remains privately owned and active, with its identity continuing to rest on international diamond and gemstone trading, processing, jewellery production and distribution, alongside a portfolio of non-jewellery interests.
