Global First: Comprehensive Online Opal Studies Course Launched by Gemmological Association of Australia

SYDNEY, AUSTRALIA – 1 MAY 2025 – The Gemmological Association of Australia (GAA) has announced the launch of its ground-breaking Certificate in Opal Studies, the world’s first comprehensive, expert-led online opal course.

“Opals have long fascinated people worldwide,” said Terry Coldham, Federal Patron of the Gemmological Association of Australia, “but until now, comprehensive education about this captivating gemstone has been available only through scarce specialist courses delivered through face-to-face teaching.”

“This program bridges gaps in understanding and allows anyone, anywhere in the world, to obtain accurate, detailed and practical knowledge about this remarkable gemstone,” Coldham said.

Responding to a growing demand for authoritative opal education, the GAA spent over three years developing its ground-breaking Certificate in Opal Studies. Designed to educate gem professionals, jewellers, valuers, traders, researchers and enthusiasts, it provides insights into everything from opal’s geological origins, historical significance, identification and classification, to value factors and opal usage in jewellery and trade. Other highlights include modules on opalised fossils, ethical sourcing, and opal markets and commercial practices globally.

“The GAA Certificate in Opal Studies provides a titanic amount of opal gemmological knowledge. The program is thoroughly recommended,” said Ken Scarrat, Vice President, World Jewellery Confederation (CIBJO) and Dean, CIBJO Academy.

Innovative Educational Opportunity

The new online course represents a significant milestone in gemmological education, offering both professionals and enthusiasts an unparalleled opportunity to acquire specialised knowledge about opal. This unique curriculum is the first of its kind, with rigorous training developed by leading opal gemmologists working in collaboration with the not-for-profit Australian Opal Centre and drawing on the expertise, experience and resources of opal industry members worldwide.

The result is a course providing unprecedented coverage of opal, from its geological origins through mining, production and markets to the wearer or collector. Students can study anytime, anywhere, making expert knowledge on opals more accessible than ever before.

The course is structured into 11 interactive modules, covering topics such as:
