The science of gemmology is a hybrid of many different scientific disciplines including not only geology, mineralogy, physics and chemistry but also biology, zoology and botany. This course explores a very select group of gemstones (coral, jet, amber, ivory and pearls), formed through organic processes rather than through geological forces deep within the earth’s surface. After completion, students may upgrade to ‘Coloured Gemstones’ and receive a credit equal to the value of the cost of this course towards Coloured Gemstones.
