At Single Source™, our commitment to exceptional quality extends far beyond aesthetics. That's why we proudly partner with Grandview Klein Diamond Group (GKD), a diamond supplier whose ethics and standards align seamlessly with our own values. When you select a diamond sourced from GKD, you're not only choosing exquisite beauty but also the confidence and integrity behind each stone.
Ethical Excellence Certified by the Responsible Jewellery Council
Grandview Klein Diamond Group is proudly certified by the Responsible Jewellery Council (RJC) through 2027, adhering strictly to its rigorous 2019 Code of Practices. This certification is globally recognized as the gold standard for ethics, transparency, and responsibility within the jewelry industry. GKD's processes have undergone extensive audits covering over 30 globally acknowledged ethical and business-related provisions.
Blockchain-backed Transparency with Tracr™
Going beyond industry norms, GKD employs Tracr™, the world's leading blockchain-based diamond traceability platform, powered by De Beers. Every diamond receives a unique digital identity, ensuring its journey—from mining through polishing to retail—is digitally secured, verifiable, and immutable. This technological innovation guarantees complete transparency and consumer confidence.
Responsible Sourcing and Human Rights Commitment
Diamonds sourced through GKD by Single Source™ are fully compliant with strict due diligence processes mandated by the RJC's Code of Practices. Each diamond is confirmed conflict-free through the Kimberley Process and the World Diamond Council’s System of Warranties. GKD's direct partnerships with renowned mining companies in Botswana, Namibia, and South Africa further reinforce their dedication to ethical sourcing, supporting national development and responsible mining.
Safe and Equitable Working Conditions
The integrity of GKD extends to the heart of its operations, ensuring safe and healthy working conditions, prohibiting forced or child labor, and guaranteeing fair wages and working hours. Employees across their operations are treated with dignity, respect, and inclusivity. GKD proudly exceeds RJC labor standards:
- Botswana: Polishers earn up to four times the minimum wage.
- Namibia: Workers receive double the national minimum wage, plus additional benefits.
- South Africa: Skilled employees earn significantly above local living wage standards.
Clear and Honest Product Disclosure
GKD maintains absolute transparency in product disclosure, strictly adhering to accurate descriptions regarding diamond treatments, origins, color, and clarity. Advanced testing technology ensures each diamond is precisely as represented, guaranteeing trust and satisfaction.
Rigorous Supplier Verification
Beyond just sourcing diamonds, GKD thoroughly vets every partner through comprehensive Know Your Customer (KYC) and Due Diligence procedures. This ensures complete transparency and accountability throughout the supply chain, eliminating risks associated with unknown or questionable intermediaries.
Uncompromising Internal Standards
GKD's stringent internal controls proactively prevent bribery, fraud, and environmental abuses—not only within their own operations but extending to every partner. Their meticulous processes and ongoing independent audits by RJC-trained experts solidify a foundation of unwavering ethical compliance and accountability.
Independent Audits: Assurance You Can Trust
Crucially, Grandview Klein Diamond Group does not self-certify. Independent experts rigorously audit every aspect of GKD's business—from sourcing records to employment policies. Certification is only granted if standards are fully met, assuring you that every diamond we source through GKD meets the highest ethical standards.
By partnering with Grandview Klein Diamond Group, Single Source™ proudly offers diamonds that symbolize not just beauty and brilliance, but integrity, responsibility, and a commitment to excellence. Trust that your diamond’s journey is as flawless as the stone itself.
