The Gemological Institute of America’s diamond grading program
When diamond grading education is concerned, the GIA is the world’s leader, hands down. The institute was established in 1931, in Carlsbad, the U.S. For almost a century it has standardized the diamond trade and has hugely impacted the way we understand and talk about diamonds.
The GIA has been accredited by the Commission of Schools and Colleges as an educational institution. Their diplomas and certifications are the most respected in the world today. However, they are neither cheap nor easy to obtain.
The GIA has an abundance of courses, programs, and online materials for any would-be gemologist. If you want to get the full merits out of a GIA education, you should complete one of their diploma programs. Currently, their diploma programs include applied jewelry professional, graduate in colored stones, graduate in diamonds, graduate gemologist, graduate jeweler, graduate pearls, and jewelry design and technology programs.
The Graduate Diamond program offers hands-on experience with the GIA International Diamond Grading System based on the 4Cs. Students will learn how color, clarity, cut, and carat weight affect the value of diamonds. Students will learn to grade diamonds based on the D-to-Z scale and distinguish lab-grown diamonds, treatments, and stimulants from natural diamonds. Students also learn when advanced testing is necessary, using specialized lab equipment. Apart from grading, students also learn about the market supply and demand factors that affect the prices of diamonds.
The Graduate Diamond program is available on location in one of the GIA campuses in Bangkok, Carlsbad, New York, Hong Kong, Seoul, Taipei, and Mumbai. The program is also suited for distance learning, with various online learning classes, combined with hands-on lab classes. The on-campus mode is a full-time study program, while the distance mode follows a more leisurely pace. The possible career paths that the course opens up include diamond buying, sorting, grading, retailing, wholesaling, and even specializing in auction house jewelry.
The Gemmological Association of Great Britain’s diamond grading program
The Gemmological Association of Great Britain or Gem-A is the world’s oldest diamond educational institution. It was established in 1908 with the start of the Gemmological Committee in Great Britain. They were the first who set the standards for modern gemology classes. Their most famous student, Robert Shipley, went on to establish the GIA. Other graduates of Gem-A are in leading positions among international gemstone organizations.
Today Gem-A is a prestigious institution with educational authority that is recognized all over the world. The association offers a combination of workshops, short courses, online materials, and two tracks of graduate courses. The first track concerns gemology, and the second one focuses specifically on diamonds.
Completing each of the two tracks takes between 4 and 9 months of teaching depending on the method of instruction. Students may study in person at one of the international Gem-A accredited teaching centers or they can study online.
Currently, there are teaching centers in Bahrain, China, France, Greece, India, Italy, Japan, Madagascar, Myanmar, the Netherlands, Singapore, Sri Lanka, Sweden, Thailand, the UK, and the U.S. Classes are available in English, French, Japanese, and Simplified Chinese.

The qualification received at the end of the study is Gem-A Level 5 Diploma in Gem Diamond (Ofqual level 5). The course fees start at 3300 pounds sterling.
During the course, students learn to recognize and describe the chemical structure of a diamond and understand how it affects its physical and optical properties. Students learn to distinguish between natural, treated, and synthetic diamonds, as well as diamond stimulants. Students will be able to make observations of rough diamond crystals and reliably communicate them using the Four Cs to estimate a diamond’s value.
Students also become acquainted with the intricacies of the diamond supply chain from mine to market. Students also receive training on diamond grading, testing, and cutting. Lastly, they are also taught about diamond ethics and traceability.
After completing the diamond track, graduates are eligible to apply for membership within Gem-A, as well as becoming a fellow or a diamond member (FGA and DGA) of the gemological association. They can also continue their studies in gemology foundation and diploma. If they complete both tracks they become eligible to study for a BSc in Gemology & Jewelry Design.
