No. Prior gemology knowledge is helpful but not required. Day 1 begins with foundations and instrument practice, while those already in the trade can deepen judgement through specimens, treatments and market work.
The course shares the same professional language used on GUILD pearl reports — type, quality factors and treatment concepts — so you can read certificates and market descriptions with greater confidence.
Sessions are offered in major cities such as Shenzhen, Guangzhou, Shanghai, Beijing and Zhuji. Day 4 includes a pearl market field trip at the host location. Check the schedule for upcoming dates.
