aigs course


The Asian Institute of Gemological Sciences was founded in 1978 as South Asia’s first educational facility devoted to gemology. They are recognized as the world authority in colored gemstones. Since the beginning of mankind, Asia has been a source of the world’s finest gemstones, so the founding of AIGS was ideal.

Because AIGS is based outside the U.S., the accreditation standards and requirements are dissimilar to those in America. It is therefore difficult to place a label of accreditation on AIGS, but by no means dismisses the legitimacy of the institution. Like GIA, AIGS offers both on-campus and distance education. AIGS offers the following gemology classes:

Introduction to Gem and Gemology
Countertop Sketching
Gem Identification
Understanding Basic Gemology Program
Diamond Grading and Pricing
e-Commerce Workshop
Colored Stone Grading and Pricing
Gem Photography Workshop
Synthetics and Treated Gem Identification
Basic Diamond Grading and Pricing
Jewelry Design
Basic Ruby and Sapphire Grading and Pricing
Jewelry Computer Aided Design
Basic Ruby and Sapphire Treatment I.D.
