Diamonds, gemstones
Independent Gemmological Laboratory (IGL) is a gem laboratory in central Sydney.
What it does
Diamond grading and gemstone identification reports.
Using any laboratory
- Ask what the report will state (identity, treatment, origin, grade) and how long it takes; turnaround and fees change.
- Check a report online with the laboratory's own report-check service, and match the stone to the report.
- Reports from different laboratories can differ, especially on colour grades, treatment and origin. A report is an opinion based on the tests made, not a valuation.
