Course Objective

From the origins of the name, to their formation within the earth's crust, to the mistaken belief that they are purveyors of bad luck to the optical phenomenon that produces such a mesmerizing and tantalizing array of spectral colours and patterns, opal is indeed a 'stone of mystery'.

Jade, on the other hand, is not only desired and valued for its beauty but also for the unique and venerable position it has held in the cultural fabric of many great and storied civilizations, from the Chinese empire, where it was once considered its most valuable commodity, to the pre-Columbian civilizations of the Olmec, Maya, and Aztec of Central America (Mesoamerica), who valued it more than gold, to the Maoris of New Zealand.
