PROVENANCE & CONFIDENCE

Know the story.
Ask for the evidence.

A diamond’s grade and its journey answer different questions. Good documentation makes that distinction clear.

Grading

Describes tested characteristics of a stone. A report is not automatically a complete record of where it was mined or how it travelled.

Provenance

Concerns origin and journey. Ask what the records cover, who supplied the data and how the diamond was linked through each stage.

Trade controls

The Kimberley Process concerns rough-diamond trade. It does not certify individual jewellers; a polished stone still needs relevant sourcing evidence.

Useful next questions

Does a report number prove I have the right diamond?

No. A report check compares information with a laboratory record. Ask a qualified professional to check that the stone itself corresponds with that report.

Does traceability prove every sustainability claim?

A chain of custody and an environmental claim require different evidence. Ask for scope, methodology, independent assurance and the period covered.

What if a seller cannot provide complete origin records?

Ask them to state the limitations in writing. Decide whether the available evidence meets your requirements before proceeding.
