I took a gemology course from ggia.ir and it exceeded my expectations. The instructors were knowledgeable and conducted the classes in a way that made it engaging and easy to understand. The course material was comprehensive and provided valuable insights into the world of gemology. The practical demonstrations and hands-on experience were a highlight. I'm grateful for the knowledge I gained from Goharneshan gemological institute.
