Laboratory
E.G.L. South Africa
Johannesburg, South Africa
Diamonds, coloured stones incl. tanzanite, jewellery
EGL South Africa is a gem laboratory in Johannesburg serving the southern African diamond and jewellery trade.
What it does
Diamond grading reports, coloured stone identification including tanzanite, and jewellery reports for retailers and the public.
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.
