in the gemological industry. He soon launched a book titled Gemology and
approximately 250 jewelers enrolled in the course. The well known G.G. Diploma
was later launched in 1948. today it has grown to have courses in its various
campuses in Carlsbad, Los Angeles, New York City, Hong Kong, Italy, Japan,
