I attended a gemology course at ggia.ir and it was a fantastic experience. The course material was thorough and well-organized. The instructors were passionate about their subject and made the classes engaging. They provided practical hands-on experience, which was invaluable. The certification I received from Goharneshan gemological institute has opened up new career opportunities for me. I'm grateful for the knowledge and skills I gained during the course. Highly recommended!
