Our close relationships with the world’s premier diamond mining companies enables us to assure our clients a regular and unrivalled supply of rough diamonds well into the future.

We participate in all major tenders and auctions.

Our rough procurement and polished diamond divisions are in continuous, open communication. This enables us to tailor our procurement as much as possible to the demands of our customers at the time. 

Depending on our own needs in polished stones, we trade the rough that will not be sent for manufacturing.


To preserve our high standards and reputation, we are extremely careful with the procurement of every rough diamond that we buy. 

All our diamonds are conflict-free origin and have been sourced from countries that are participant in the Kimberley Process.

We require our suppliers to propose only diamonds that have been procured through a conflict-free process and from sources that adhere to our standards of human rights.


Rosy Blue and its alliance entities sell parcels of rough diamonds sourced either from mining companies or from the open market. These are sorted and sold through our business alliance entities.

Our extensive range of rough diamonds includes:

  • Sawables
  • Makeables
  • Cleavages
  • Industrials
  • Crystals

Our Israel office also offers rough diamonds sawn and prepared for polishing.
