Learning objectives
The course offers a broad introduction on (i) the mineralogy and genesis of gem-quality minerals and (ii) the main physical and optical techniques used in the gems characterisation.
Expected learning outcomes
Participants will acquire skills on gems mineralogy and genesis and will be able to identify and characterise them by means of physical and optical techniques
Course syllabus and organization

Single session

Responsible
Lesson period
Second semester
Online learning using the tool Microsoft Teams; the knowledge will be transferred by using asynchronous, self-paced digital materials, such as video clips recorded by the professor followed by online sessions where the teacher will verify the acquired competencies with online tests (using PollEveryWhere), will engage in discussion around the key concepts and will present real cases and examples.
Course syllabus
1) Introduction to Gemology; 2) Definition of the gem (natural gem, synthetic gem, imitation) and their fundamental properties; 3) Systematic gemology: the gems with the highest market value; 4) Mineralogical properties of gems; 5) Physical properties of gems (color; transparency; weight; optical properties); 6) Genesis and deposits of gems; 7) Analytical methodologies for gems characterization: conventional analytical techniques and synchrotron radiation; 8) Diamond and its classification; 9) from minerals to gems: quartz, corundum, beryl, tourmaline, garnets, and their gem varieties; 10) Gems as resources: economic value and their use in art.
