We are proud to offer high-quality sustainability certified lab grown diamonds from our partner, WD Lab Grown Diamonds. The first laboratory grown diamond company worldwide to be Certified 100% Climate Neutral and to achieve the highest level of Sustainability Rating, WD is reimagining the diamond industry through new standards of transparency, innovation, and ethics. WD Lab Grown Diamonds offers fully traceable, U.S.A. grown, guaranteed conflict-free laboratory grown diamonds.

ARE LABORATORY GROWN DIAMONDS REAL?
Yes, laboratory grown diamonds are real diamonds. WD laboratory grown diamonds are created in their state-of-the-art laboratory outside of Washington, D.C., leveraging the company’s patent perfected Chemical Vapor Deposition (CVD) diamond growth process, resulting in the purest form of diamond – Type IIA – which qualifies each diamond as one of the rarest on earth (only 1-2% of earth grown diamonds are Type IIA). WD laboratory grown diamonds are physically, optically, and chemically identical to their mined diamond counterparts, and are brilliantly As Grown, without requiring post-growth treatment.
LABORATORY GROWN DIAMOND GRADING: THE 4Cs AND BEYOND
Each WD laboratory grown diamond purchased through J. Thomas Jewelers is cut and polished to optimize its fire and brilliance and graded according to the traditional 4C qualities established by the world's leading gemological laboratories. WD diamonds are also individually certified against The 5th C: Climate Neutrality™. Setting a new standard in diamond excellence—this third-party verification, certified by sustainability standards organization SCS Global Services, Inc., reflects WD's net zero carbon footprint, and the negation of all legacy and current environmental impacts.
SCS certification equates to 100% climate neutrality, a net zero carbon footprint, 99.9% transparent U.S. origin traceability and chain of custody, 75% net zero sustainable production, legitimate ethical stewardship and the protection of workers and their communities.
As an SCS Global Services Accredited Retailer, we are pleased to offer our customers Sustainability Certificates to accompany your WD Sustainability Rated diamond. Each WD Sustainability Certificate serves as a permanent record of the fully traceable journey of an SCS-007 Sustainability Rated diamond. Aligning with the unique certificate ID inscribed on each diamond's girdle, and cross-referencing core physical attributes, this third-party issued certificate also details WD's accomplishments under each of the Five Pillars of Sustainability benchmarked against the SCS-007 Sustainability Rated diamond standard.
FIVE PILLARS OF SUSTAINABILITY:
1. Grown in the U.S.A. traceability and Chain of Custody
2. Guaranteed protection of workers, communities and ecosystems
