Founded in 2008, WD Lab Grown Diamonds is the leading producer of laboratory grown diamonds in the United States, headquartered outside of Washington, D.C.  A pioneering materials science company, we leverage our patented and proprietary processes to create high-quality, conflict-free, guaranteed-origin and fully traceable diamonds for the modern consumer.

Certified under SCS Global Services’ Sustainability Rated Diamond Standard, WD is the first company worldwide to offer third-party Certified Sustainability Rated and 100% Climate Neutral diamonds — ‘As Grown’, without requiring post-growth treatment or color enhancement. Our ongoing R&D efforts, coupled with our strategic acquisition of colorless diamond growth laboratory J2 Materials, enable us to achieve bespoke production at a commercial scale — targeting color, shape, and size according to our customers’ needs.

Leading the charge in the disruption of the $15 billion North American diamond gemstone market, and expanding onto the international stage, WD is setting a new standard for integrity, transparency, and sustainability in the industry. Our purpose-led brand evolution continued with the 2021 launch of our consumer-facing diamond brand, Latitude.
