About

My name is Nikoleta Tzankova – a gemologist and mineralogist.
As a result of my education (Bachelor’s Degree in Gemology, Master’s degree in Applied Mineralogy, Ph.D. in Mineralogy and Crystallography, Diamond grader and Colored stone grader – IGI) and many years of professional experience as a university lecturer at the University of Mining and Geology “St. Ivan Rilski” Sofia, I found the joy of encouraging and motivating knowledge seekers.
My publications and projects are in Gemology science, Mineralogy, Crystallography, and Archaeomineralogy. I am interested in gemstone testing, synthetics, imitations, treatments, and deposits.
My expertise in archaeometry concerns the non-destructive study of metal and mineral artifacts, archaeological glass, ancient tools, and slags.

We can communicate professionally in English, Russian, and Bulgarian languages.
