- Every gemstone submitted is tested and screened at multiple steps during the grading process. If a determination is inconclusive at one lab location, the gemstone will be routed to another for further testing.
- A global database captures hundreds of data points for every diamond during the grading process and is used by ILGD researchers to detect emerging trends in treatments.
- Control stones for diamond grading standards also move anonymously through ILGD’s worldwide system to ensure uniformity of grading practices.
- Teams of highly experienced quality controllers rotate through ILGD worldwide laboratories training staff and to ensure adherence to consistent practices.
