Compared with the well-known reddish browns and purplish red garnet varieties of pyrope, almandine, and spessartine, the second solid solution series producing gem quality garnets generally goes under the radar of your average jewellery customers.
Historically, garnets have played a significant role in the world of gems. They have adorned the necks of high society ranging from Egyptian pharaohs to Victorian-era royalty and beyond.
To the average consumer, or even the average jewellery sales assistant, pearls are often known to be gloriously lustrous, covered in glittering nacre, as close to white as possible, and aiming to be perfectly round.
Seed pearls have long been a favourite choice for intricate designs throughout jewellery history, whilst the baroque forms of keshi pearls are today featured to bring jewellery design a touch of uniquity.
Typically round in shape, white or cream in colour with a pinkish overtone, and possessing a high lustre – Akoya pearls are a classic. For consumers of the western world, these saltwater cultured pearls are the most popular choice.
The Gemmological Association of Australia (GAA) is Australia’s long established gemmological educator. Since 1945, the Association has been responsible for producing Australia’s gemmologists by educating and updating members of the gem and jewellery industry and the general public, about all aspects of gemstones and their substitutes.

Why GAA?
We are passionate and enthusiastic as evidenced in our dedicated team of professional educators and volunteers. Being a not-for-profit organisation provides assurance that we operate with the best interests of our members and students in mind

Our lecturers and demonstrators maintain a high academic standard whilst ensuring that what students study is also relevant. Restricted class sizes ensure that everyone receives adequate attention. With the GAA having Divisions in every state in Australia it means that our graduates become part of a local gemmological community – of benefit for networking and ongoing training.

On the job training, with its many benefits, is simply not enough these days. Can you confidently identify a diamond imitation like synthetic moissanite? A beryllium treated sapphire? Or laser drilled diamond? Not being able to answer such questions as these can cost a business thousands, not to mention reputation. Confidence and Knowledge sells.
