What will I learn?
The Precious Stones Course provides you with practical skills to identify, grade, and value gems with confidence. Learn refractive index, specific gravity, inclusions, and the 4Cs using basic tools, then compare natural stones, synthetics, and simulants. Understand lab reports, treatments, ethical disclosure, and real-world pricing so you can spot risks, support accurate quotes, and make informed buying and selling decisions.
