International laboratory certificates

The certificates of international gemological laboratories are important documents that provide information about the quality and individual properties of gemstones. These certificates are issued by independent institutions and provide customers with certainty and confidence when purchasing gemstones.

Some of the most well-known international gemological laboratories that issue certificates include: The GIA (Gemological Institute of America), the IGI, HRD and EGL. Other gemological laboratories that also certify color gemstones are AGL (American Gemological Laboratories) and GRS (GemResearch SwissLab)

These international laboratories conduct thorough analysis and tests on gemstones and issue certificates that contain information about their properties, quality and authenticity.
