Founded in 1996, the gemmology unit of AMGC has grown to be an internationally recognized unit servicing gemstone miners, dealers and buyers in areas of identification, certification, training, advisory and consultation services.
Gemstone Identification and Certification
The numerous gemstones offered in the trade, the discovery of new gemstones, varieties and occurrences as well as synthetic and imitation stones require a detailed understanding through gemological knowledge of the material available on the market. AMGC's gemological unit examines and identifies gemstones and their numerous imitations and certifies them.
Diamond Grading
AMGC's gemmological unit identifies, distinguishes between diamond and their simulants as well as carrying out grading and gives expert opinions.
The MPG department provides the following courses:
  • Mineralogical and petrological sample preparation and analysis techniques: A three week training course offered to technicians from mineralogical and petrological departments from different institutions such as Geological Surveys and Universities
  • Gemmology: A one week training course offered to mineral and gemstone miners, dealers and all interested parties
  • Gem cutting: A two weeks training course offered to mineral and gemstone miners, dealers and all interested parties
The department in collaboration with other departments is carrying out research and development activities, including evaluation of raw materials for industrial application.
AMGC's mineralogy and petrology department provides advisory and consultancy services to the mining community and proactively promotes the sector by conducting training programs.
