Know the diamond you choose.
The International Gemological Institute (IGI) is an independent gemological laboratory. Its laboratory-grown diamond reports identify origin and record assessed characteristics, including carat weight, color, clarity and cut details where applicable.
Read the report.
- Check the laboratory-grown origin and unique report number.
- Review the recorded carat weight, color, clarity, measurements and applicable cut information.
- Enter the number on IGI’s official verification page and compare the official record with the report document.
Report availability is stated for each individual product. A general introduction to IGI does not mean that every piece includes an individual report.
