From geological formation to laboratory examination and market evaluation, learners study physical, optical, and chemical properties, microscopic identification, and practical trade testing methods used by gemologists, jewellers, and gemstone buyers. The course also explains natural vs synthetic and simulant separation, disclosure standards, cutting quality, durability, and pricing factors, linking gemological theory with real jewellery trade practice.
