Full Transparency

Sustainability isn’t black or white. The Sustainability Rating provides the level of transparency you need to understand exactly how well your diamond performed. The overall score is the combined average of the specific ratings achieved under each of the following pillars – origin traceability, ethical stewardship, climate neutrality, and sustainable production practices – reflecting conformance to the relative criteria.
