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 BScH, Cert. IV TAE, DipDT, FGAA 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.


Julie Charnley FGAA, Diamond Grading, NCJV Registered Valuer, BA Vis Arts Applied Design, GIA Pearls Graduate Theory Lecturer GEM1/GEM2

My passion for jewellery and gemstones has been in me since I was a young girl and I have managed to simultaneously continually advance my education with my professional experience and industry skills while working as a jewellery designer and valuer for leading manufacturers in Adelaide and London since 2006. I have been a member with the GAA since 2009, and a registered valuer with the NCJV since 2015.


Sarenah Gallasch FGAA Theory Lecturer GEM1/GEM2

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. I currently lecturing in Opals, Ornamentals, other and lesser known gems


Laura Phillis FGAA, Diamond Grading, Advanced Diamond Grading South Australia President

I first discovered the world of gemmology working in a second hand jewellery store back in 2010. From there my passion grew and I went on to become a member of the GAA in 2012 and completed many of the short course and also the Diploma of Gemmology and diamond grading components. After completing my studies in 2014, I began lecturing theory part time for the GAA in 2015 and have been teaching since. While working in the jewellery industry for the past 10 years I worked in many areas of the trade, but found a passion in gem cutting in 2014 and turned it into a professional career.


Sandra Pimlott FGAA, Dip DT, NCJV Registered Valuer South Australia Secretary

I have a passion for jewellery and wanted to know what I was buying for myself from antique markets, so I studied Gemmology in 2006/2007 and then Diamond Tech in 2008. I commenced teaching Gem 2 prac and then Gem 1 Prac diploma students, as I am wanting to share the wonderful knowledge of gemmology. I started working in the jewellery industry in 2014. I completed the NCJV valuers course in 2013, but currently at this stage no longer undertake valuations in my own business.
