Diamond certification and grading reports

A grading report is an independent record for a specific submitted diamond. It is useful evidence, but it does not certify every stone in a piece or replace the seller’s product and service obligations.

What a report can contain

  • Laboratory report number and diamond identification details
  • Lab-grown or natural origin conclusion
  • Shape, measurements, and carat weight
  • Colour and clarity grades
  • Cut-related grades where the laboratory provides them
  • Polish, symmetry, fluorescence, proportions, and comments

Which Ichor stones receive reports

IGI reports apply only to qualifying centre or selected stones when the product or order documentation states that a report is included. Smaller accent or pavé diamonds are not automatically individually reported. A jewellery piece should not be described as wholly “IGI-certified” merely because one selected stone has a report.

Confirm the report number and measurements correspond to the stated stone.

2

Verify

3
