Matching quality with integrity - Rosy Blue, a leading diamantaire of international reputation.

In the course of over 50 years, Rosy Blue has become one of the world’s largest and most influential diamond manufacturers.

Matching quality with integrity

Rosy Blue is a diamantaire of international reach and reputation. Over time, we have become one of the largest and most trusted names in the global diamond industry.

This success is due as much to the integrity of our approach as to the exceptional quality of our diamonds. Rosy Blue is respected by those at every level of the industry for our steadfast commitment to the highest ethical standards. We do not only succeed for ourselves, but also to deliver positive benefits for our suppliers, customers, our employees, and the communities in which we work and live.


Rosy Blue is one of the world’s foremost diamantaires, with a long and distinguished history of excellence in the diamond industry. Rosy Blue is a global leader in the manufacture of high-quality polished diamonds and finished jewellery.

In each country, we combine the scope and strength of an international business alliance with our local team’s in-depth knowledge of their particular market.

The business is divided into three key operations: Rough Diamond Procurement, Rough Diamond Manufacturing, and Polished Diamonds. Although independent, these operations are united by a customer-centric approach and underpinned by strong, long-standing relationships. Our dynamic international structure allows us to identify and capitalise on opportunities wherever and whenever they arise.


As an industry leader and De Beers Sightholders, Rosy Blue has access to a regular and consistent supply of diamonds, thanks to our close relationships with all the major mining houses, including De Beers and Alrosa.

We also have a dedicated team of global buyers, actively procuring stocks from the worldwide markets. So we are always ready to deliver against the precise needs of every customer, anywhere in the world.

Manufacturing is the heart of our business and reputation. We have core production centres, working to an advanced series of control systems that drive quality and guarantee the integrity of the pipeline.

We are always upgrading our production technology and processes, maintaining state-of-the-art factories that meet the highest technical standards. We produce stones ranging from rounds (0.005 points to 30 carats) to calibrated princess diamonds (0.03 points to 2+ carats), as well as a wide variety of round-edged fancy shapes.


‘We view sustainability as both a responsibility and an opportunity’ — Amit Bhansali, Member of the Rosy Blue Brand Council and Member Management Board

As a major international business, we see ourselves as a global citizen, with a responsibility to contribute to the environmental and social good of the world. Hence our membership of the Responsible Jewellery Council, and participation in the UN Global Compact.

In 2011, we also joined Global Compact LEAD, an exclusive new sustainability leadership platform launched by HE Secretary-General Ban Ki-Moon at the World Economic Forum in Davos. By joining this sustainability leadership initiative, Rosy Blue commits to take sustainability leadership to the next level.
