Worth knowing
The laboratory is a separate company operating in affiliation with the International Colored Gemstone Association; the association itself is a trade body and does not issue reports, so ICA membership and an ICA GemLab report are different things. Online QR verification applies to reports issued after 1 July 2025. Locations listed are Bangkok, Dubai, Hong Kong and Taipei.

We verify dealers, not stones. A laboratory report describes one stone on one date; it is not a guarantee of value, and it is not ours to stand behind.
