A discussion on Imitation Opals

Earlier this year and due in part to not being able to meet as everyone will say “covid19” I was approached by the Scottish Gemmological Association to give a presentation via “Zoom’ to the members for their usual annual conference. This was something significant and I was really privileged to do. The presentation , albeit with one or two “quirks” is available here for anyone to view. The presentation runs for about 40 minutes.
