After Five years of study, The Gems & Metals Calibration Lab was established as the first laboratory specialized in examining and grading diamonds and gemstones.
Our lab will effectively contribute to accelerating development in the State of Qatar since 2011.
The establishment of this laboratory is considered an integral part of Qatar’s economy today as it will keep pace with the change in the concept of individual consumption and the view of purchasing priorities.

Prioritizing high standards, GMCL is backed up with state-of-the-art technology and skilled professionals. We commit ourselves to contributing to and maintaining a sustainable gemstone industry and its mission to protect its clients and the trade by providing them with accurate and relevant information
