Ever wondered what makes a ruby red, an opal flash with colour, or how to spot a fake from the real thing? This popular course from the Gemmological Association of Australia is your entry point into the fascinating world of gemstones.

Delivered as a 2-day intensive, the course covers gemmology basics, the science behind colour and optical properties, gemstone origins and geology, organics like pearl and amber, and how synthetics are made and identified. You’ll also get hands-on time in a practical laboratory session using real gemmological instruments — loupe, microscope, polariscope, refractometer, UV light, spectroscope and hydrostatic balance.

Dedicated sessions dive into coloured gemstones, diamonds, corundum (sapphire and ruby), cutting and faceting, and Australia’s own national gemstone, opal.

Perfect for hobbyists, gem enthusiasts, and anyone considering a career in gemstones or jewellery. No prior experience needed — just curiosity. Includes a course manual and lecture notes to take home.
