Program Overview :
Objective of this program is to impart knowledge of Gemmology
(scientific study of gems) to the students and the people already
associated with or desirous of entering in the field of gem industry
as importers, manufacturers. As the program covers all the aspects
of gemstone identification, it is useful for traders, dealers,
dealers artisans and common people. It offers wide scope to those
seeking job in the gem world & is useful to the hobbyists.
