Gemspact Gemological Laboratory

GGL is a gemological laboratory established to certify minerals sold by Gemspact, Prague. The laboratory specializes in identifying mineral species and determining their physical and chemical properties. The certificate contains the results of gemological examinations conducted using methods and techniques designed for this purpose. GGL is not a commercial entity and does not issue certificates for third-party minerals.

The certificate confirms that the certified information about the mineral is accurate and corresponds to the description of the mineral being sold. The certificate is provided along with the mineral being sold. Both the certificate and the box are protected by holographic security features. The mineral is delivered in a transparent box consisting of two parts marked with a serial number—the certificate number. Opening the box invalidates the hologram. The certificate is not transferable to another mineral.
