Jewelry Sustainability & Traceability
Sustainable Choice Diamond Certification
Move beyond unverified sustainability claims. Sustainable Choice Diamond Certification provides an independent, third-party framework for substantiating diamond sustainability and traceability claims through rigorous sustainability criteria, life-cycle assessment, and robust chain of custody.
Choice : The 5th C
Traditional metrics – Cut, Color, Clarity, and Carat – measure a diamond’s physical attributes. ECG introduces Choice as the 5th C: the consumer’s power to select a diamond whose story, impact, and provenance have been independently verified.
Sustainable Choice sets apart diamonds supported by auditable sustainability criteria, quantified life-cycle impacts, and documented chain of custody—elevating purchase from preference to informed choice.
Sustainable Choice Diamond Certification
Sustainable Choice Diamond Certification helps producers, manufacturers, traders, and retailers support credible market-facing claims with technical rigor. The framework brings together sustainability criteria, life-cycle assessment, and chain of custody controls to provide a defensible basis for environmental, social, governance, climate, and traceability assertions across the diamond value chain.
Why Move from Claims to Certified?
Independent certification matters because it helps companies:
- demonstrate conformance with key environmental, social, and economic requirements,
- provide assurance to producers, retailers, NGOs, and other stakeholders,
- strengthen the credibility of market claims, and
- support a more disciplined sustainability pathway going forward.
The Sustainable Choice Model
Sustainability Criteria
Independent evaluation of social responsibility, governance, environmental accountability, diamond traceability, and climate accountability. The standard covers business integrity, stakeholder engagement, human rights, community engagement, etc.
Life Cycle Assessment
Comprehensive life-cycle assessment across 14 environmental and human health impact categories. The framework uses an LCA impact profile and sustainability rating methodology to quantify relevant impacts across the diamond value chain.
Robust Chain of Custody
Documented traceability from mine to market. The chain-of-custody component includes site inspections, documentation trails, and controls for both B2B and B2C claims, including retailer/seller code-of-practice requirements.
