These connections have helped in ensuring a steady rough supply of diamonds on a consistent scale. Being part of a very elite group, our scale of sourcing translates into a very large, consistent, and secure stream of supply for our clients
Supply chain integrity
The integrity of the diamond that is a symbol of love, live, commitment and so many other important events in our lives is vital.
