We have key production centres around the world, combining the traditions of diamond craftsmanship with the world’s most advanced cutting and polishing technology.
We monitor all the diamonds we handle, ensuring their ethical provenance. This is also verified through a number of third-party assurance programmes, not least the Forevermark programme from De Beers.
Rosy Blue and its alliance entities have state-of-the-art diamond manufacturing centres around the world, where our heritage in craftsmanship and expertise meet the most advanced cutting and polishing technology in the world.
Our key manufacturing centres are:
- Belgium: Gem-quality round diamonds (10+ carats)
- Israel: Princess and square diamonds, and fancy shapes
- Thailand: AGS 000 diamonds, princess and square cuts
- Sri Lanka: Three grains and above, in medium and better
- India*: 0.1 pts to 3 carats, in medium and better-end rough
Our manufacturing focuses on better-quality goods of SI quality or above. These are mainly round stones (0.005 points to 10+ carats), but we also produce princess diamonds (0.03 points to 10+ carats), and a range of round-edged fancy shapes.
We handle AGS 000 stones, the hardest stones to cut, and GIA ‘Triple Excellent’ diamonds, as well as ‘Hearts and Arrows’ stones.
We also have proprietary, patented cuts, including the Cento: a 100-facet diamond that demands the most exceptional craftsmanship and expertise. We are always ready to discuss specific designs and ideas, and to develop new cuts to meet every requirement.

INSPIRED BY CUSTOMERS
“In today’s competitive and dynamic marketplace, customer satisfaction is crucial to securing a leading edge. Rosy Blue is committed to innovation and to delivering the best products and services, thereby improving people’s quality of life and contributing to a better global society.” – Mayank Mehta, Member Management Board
Rosy Blue is a business built around the needs of our customers. In fact, we have even adapted our manufacturing approach over the years to better serve the needs of our customers.
Today, Rosy Blue has evolved a value-driven approach to manufacturing, aiming at every stage to maximise the value of the rough stone through superior makes and special cuts, from speedier delivery, and from ever-more accurate projections of demand.
From large programmes of fine makes to distinctive special cuts, our aim is always to deliver what you need, exactly when you need it.
INVESTING IN PERFECTION
“We need the diverse talents and full potential of every individual employee in order for Rosy Blue to excel as a leader in the global marketplace. Our diverse workforce is critical to exploring new ideas and creating innovation.” Ravi Bhansali - Member of the Rosy Blue Brand Council
We are continuously innovating, developing and investing in our manufacturing technology and processes, to maintain our leadership position in the global diamond industry. Our current manufacturing technology includes:
- Lexus helium polishing, which is a highly accurate system for calculating and achieving the maximum possible value yield from a rough stone.
- Sahajanand laser cutting and polishing, which creates the pavilion and crown of the diamond.
- Dialits automatic blocking and polishing systems
- Fantasy System and JD Edwards enterprise resource systems, to manage our inventory.
We also have a global reputation as a pioneer in technological research and development, always looking for new ways to enhance output, efficiency and excellence. For example, we are currently in the process of finalising our own, proprietary diamond colour technology.
