SEAMIC: Mineral Petrology and Gemmology Section

The Mineralogy, Petrology and Gemmological Section of SEAMIC has many years of experience in the analysis and fundamental characterisation of minerals and rocks and serving the mining community locally and internationally.

Mineralogical and petrological sample preparation and analysis
Mineralogical evaluation of industrial minerals, metallic minerals and clays
Characterisation of gold bearing rocks
Gemstone identification and certification
Diamond Grading
Advisory and Consultation
Training in mineralogical and petrological sample preparation and analysis techniques and industrial mineral assessment and Gemmology

To obtain meaningful analytical results, it is important that the sample preparation to be done properly. It is because of this that the section provides a wide range of thin section preparation, including polished blocks and resin impregnation both for in-house requirement and clients.

Industrial minerals are essential for the manufacturing sector and the infrastructure improvement. The section also carries out evaluation of industrial minerals including fieldwork, sampling and laboratory investigations. Laboratory evaluation involves a wide range of inter-related properties and must be carried out with the knowledge of the requirement of the end user.

MINERALOGICAL AND PETROLOGICAL ANALYSIS

The section has a wide expertise in the mineralogical and petrological analysis. The section offers integrated mineralogical and petrological services to clients by carrying out petrographic and mineralogical evaluations of sediments, rocks and drill cores utilising transmitted and reflected optical microscopy, X-ray diffraction and thermal analysis.

Founded in 1996, the gemmology unit of SEAMIC has grown to be an internationally recognised unit servicing gemstone miners, dealers and buyers in areas of identification, certification, training, advisory and consultation services.

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 gemmological knowledge of the material available on the market.
SEAMIC's gemmological unit examines and identifies gemstones and their numerous imitations and certifies them.

SEAMIC's gemmological unit identifies, distinguishes between diamond and their simulants as well as carrying out grading and gives expert opinions.

The section undertakes in-house training in mineralogical and petrological sample preparation and analysis techniques and industrial mineral assessment for staff and technicians from mineralogical and petrological departments from different institutions.

The section also provides short gemmology training courses to mineral and gemstone miners, dealers and all interested parties.

The section in collaboration with other sections is carrying out research and development activities, including evaluation of raw materials for industrial application.

SEAMIC's mineralogy and petrology section provides advisory and consultancy services to the mining community and proactively promotes the sector by conducting training programmes.
