Superior rough supply
Blue Star Diamonds sources rough directly from major and junior miners. We have been a regular buyer from Alrosa since 2009 while also being a Dominion Diamond Preferred Purchasers since 2007. 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. Due to our responsible sourcing practices where we only buy rough from reputable miners, both established and junior, combined with our ethical manufacturing practices, we are able to offer our clients the Forevermark and Canadamark branded diamonds.
