FYI - Opal Studies Course - Gemmological Association of Australia
Just a quick video to talk about the Certificate in Opal Studies course available from the Gemmological Association of Australia.
(The GAA and its people have supported Curiosity Mine in the past, and will continue to do so into the future. I was given free access to the course and asked to make a quick video if I felt it was deserved, which I did, and I have.)
