Dubai Central Laboratory

Dubai Central Laboratory, part of Dubai Municipality, tests products for the emirate, including gold and gems in one of the world's largest gold markets.

What it does

Precious metal testing and hallmarking, and gemstone testing.

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.
