Black Diamond is a US-based manufacturer and wholesale supplier of natural loose diamonds and custom fine jewelry, known for offering distinctive stones that go beyond the traditional white diamond. As a Kimberley Process licensee, the company sources all rough material exclusively from conflict-free, compliant nations and processes every stone in-house at its own certified fair-trade facility, ensuring full transparency from mine to finished piece.

Our collections span some of the most distinctive categories in the diamond world. Shop raw, unrefined beauty with our rough cut diamond engagement rings, each set in a one-of-a-kind natural crystal form. For designers and jewelers who need wholesale-level consistency, our melee diamonds collection offers precisely matched parcels across a range of shapes and colors.

And for a truly individual stone, our pear shape salt and pepper diamonds showcase nature's own artistry through their distinctive black-and-white inclusions.
