Maria José Trindade – on gems

Maria José Trindade graduated in Geology (Faculty of Sciences of the University of Lisbon). She also has a Master degree in Dynamic Geology (Faculty of Sciences of the University of Lisbon) and a PhD degree in Geosciences (University of Aveiro). She also has a specialization in Gemology and Diamond Grading (Portuguese Gemological Institute).

She has scientific experience in different areas, such as geochemistry, mineralogy, igneous petrology, volcanology, sedimentary basin analysis, clay deposits, external geodynamics, archaeometry, weathering of stone built heritage and compositional characterization of historic tiles. More recently, she obtained experience in the study of gemstone’s properties used for their identification and separation from fakes (synthetic and artificial substances).

Her professional activities, as a FCT post-doctoral researcher, have been developed in the Center for Nuclear Sciences and Technologies (Nuclear and Technological Campus of Technical Superior Institute). She also collaborates with Geobiotec research center (University of Aveiro). Her work has been dedicated to the application of nuclear methods and mineralogical analysis to characterize geologic and ceramic samples in studies regarding distribution of trace elements and natural radionuclides (U, Th and K) in superficial environments, as well as in provenance studies of archaeological shards and cultural heritage studies. She is author of several scientific papers in national and international journals and proceedings of scientific meetings, in addition to dozens of oral and poster presentations in international and national conferences, in a few as invited lecturer.

She was awarded as “best poster” and “young investigator” in two European scientific meetings. She is also a reviewer of scientific papers and was a member of the scientific committee of a congress and a symposium held in Lisbon.

Maria José is now developing an online gemology course for the Open University.
