100% Conflict-Free Diamonds
Every diamond in our collection is ethically sourced, transparently tracked, and strictly compliant with international human rights standards.
Kimberley Process Certification Scheme
Tesora strictly adheres to the Kimberley Process Certification Scheme (KPCS), an international protocol established to prevent conflict diamonds from entering the mainstream rough diamond market. We exclusively partner with audited sight-holders and suppliers who guarantee that every diamond is sourced from mines that maintain fair labor practices and safe working conditions.
Independent Certification (GIA & IGI)
Beyond ethical origin, every center diamond over 0.30 carats comes with an official grading certificate from the Gemological Institute of America (GIA) or International Gemological Institute (IGI). The diamond's unique certificate number is microscopic laser-inscribed directly on the girdle of the stone for complete security and verification.
Lab-Grown & Eco-Friendly Options
For customers seeking zero-mining alternatives, we offer premium lab-grown diamonds created using advanced solar-assisted technology. Lab-created diamonds possess identical chemical, physical, and optical brilliance to earth-mined diamonds while offering an eco-conscious footprint.
