Tanya Cerny FGAA, DipDT South Australia Education Support Officer

I have always been interested in rocks and earth processes. I studied geology and worked as a geologist throughout QLD and WA in the mining industry for many years.
It was during this time, I was frequently asked by people about their jewellery and gemstones. Even though gemstones are minerals, I really couldn’t offer any information on cut stones. I decided to find out, by applying for the Diploma in Gemmology, completing in 2010. I was hooked. Since then I have been lecturing and serving on the SA Div committee.


Lise Jensen BScHons, Cert. IV TAE, DipDT, FGAA South Australian Secretary, Practical and Theory Lecturer GEM1/GEM2

My interest in gems was hidden in plain sight, by the mere fact I had collected books on minerals and gemstones since childhood and didn’t know I had the interest. The interest was sparked by my grandfather who was a miner in Broken Hill, who had taken the time to show me all the nice specimens of beautiful minerals at the Broken Hill Museum.

20 years later I decided to change my career into something I’m passionate about. In 2009 I had asked myself the question ‘What am I passionate about?’ The answer was ‘Gemstones’. Then I stumbled across a website about the GAA. Began my new career path in 2010 by first doing the ‘Introduction into Gems and Gemmology’. I was hooked and enrolled into the Diploma in Gemmology in the same year.

After completing secondary school I went to work in the family retail gemstone and mineral business. Here I gained extensive experience with opals, as well as hundreds of different gemstones. It has allowed me to meet miners, cutters, jewellers and dealers from many countries. I received my GAA Diploma in 1997, and later became manager of the family gemstone and mineral business, which has now been operating for over 40years. In 2018, I completed the Gemmology and Synthetics Update course and continue to stay on top of my education which helps me to better educate for the GAA SA division.
