👍 I just completed a gemology course at Gemology Training Center (GTC) and it exceeded my expectations. The instructors were highly knowledgeable and passionate about gemology, which made the learning process enjoyable. The course content was comprehensive and well-structured. The practical sessions provided valuable hands-on experience. I would highly recommend GTC to anyone interested in pursuing gemology training. 👍
