Bauer Gemmological Laboratories (BAUER) –located in Melbourne, Australia – was established with an uncompromising commitment to excellence in producing diamond grading certificates and gemstone certificates. Our reports are developed to exacting standards and conducted by a team of highly qualified personnel with many years of industry experience.

BAUER uses the gemstone testing guidelines of the Gemmological Association of Australia and other international criteria for every certificate and uses state of the art equipment and optimum lighting conditions to conduct testing procedures. At least two, and in many cases three, members of the BAUER team scrutinize each gemstone before a conclusion is reached.

Diamond merchants, gemstone merchants, jewellers and private clients who hold a BAUER certificate can be confident of the standard and conclusions reached in the certificate’s report. Each assessed gemstone* is inscribed with a unique number, without affecting gemstone quality, for easy cross reference to the accompanying certificate.
