Graduate Colored Stones Program
The Graduate Colored Stones diploma program blends theoretical knowledge with practical application. Topics include gemstone formation, properties, sources and the colored stone supply chain. Students learn how to describe color by hue, tone and saturation, which gemstones are commercially important and what factors affect gem price and availability. The course describes the general observation process, standard gemological tests and equipment and when advanced laboratory testing and instrumentation is needed for accurate identification. Using professional gemology equipment, students identify diamonds, colored stones and simulants; distinguish natural, treated and laboratory-grown diamonds and colored stones; and grade colored stones.
