The Classification and Grading of Opal
Speaker: Mr. Eddy Wong
Eddy Wong’s father has been involved in the Australian opal trade since 1979, from buying raw material up to lapidary. Now Eddy has taken charge of the opal polishing and jewellery manufacturing factory and he will share his know ledge and experience with us. He will talk about different opal producing localities around the world, the differences between the localities and the opal grading technique. We hope you will learn more about this extraordinary mineraloid.
