The science of gemmology is still relatively young, 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.
Topics covered include their physical and optical properties, geological formation, crystal systems, chemical composition, varieties and classification, cause of colour, common inclusions and internal characteristics, fluorescence, pearl grading criteria, methods of synthesis, gem identification, common treatments and enhancements, and cleaning and care instructions.
This course includes one online test at the end of the course.
This is a 'General Interest' course. 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.
This course is available for long distance learning. You can register at any time and study at your own pace. There are no time restrictions.
