Check the report. Know the stone.

Use the report number to open the issuing laboratory's official lookup. Match the returned details to the stone and the document you have been offered.

Official report lookup

Check your report at its source

Your report number goes directly to the issuing laboratory's secure website. We do not alter the report results.

igi.org

Your number is passed directly to the official report check at igi.org.

Example: LG6412883705 or a numeric report number

Compare the details

Check the report number, laboratory-grown disclosure, shape, carat weight and measurements. Review colour, clarity and any comments or treatments recorded.

A lookup is not physical identification

A valid report number does not by itself prove that a particular stone matches that report. Compare the inscription where applicable and seek an independent examination when needed.
