At GUILD, I discovered that pearls are more than jewelry—they’re a cross-cultural art form. The program made me more confident and professional in sharing their beauty.
GUILD has a strong team of instructors who are very patient, and the quality of the classes is guaranteed. In addition to theoretical learning, a lot of time is devoted to hands-on practice, which I really enjoy.
The immersive experience of on-site learning is very strong. I really enjoy the “learn-and-practice” approach, which allows me to turn what I’ve learned into practical experience. This opportunity to study at gemstone mining sites has given me a deeper understanding of the gem industry.
