My family background is not in gems and jewellery, so I always thought that every green stone is an emerald, that every red stone is a ruby and that all blue stones are sapphires. After coming to GIA, I learnt that there are so many stones to know and learn about. GIA has been a superb experience, and what I have learnt from GIA is so much more than what I imagined. I will confidently use my knowledge as I join the ranks in the gem and jewellery industry.
“My experience of attending GIA has been delightful. Having a family business within this industry, the courses that I have enrolled in have allowed me to acquire in-depth knowledge regarding the industry, not only from a gemmological point of view, but also from a business perspective. GIA has provided me with the wonderful opportunity of studying in Mumbai. This has enriched my experience, allowing me to interact with a wider variety of people of different nationalities.”
