IDENTIFY Your Opal: Australian vs. Ethiopian

In this video, I show ways to EASILY IDENTIFY identify the origin of most types of opal and also show how to tell if your opal is synthetic. I cover Australian opal, including Lightning Ridge Black Opal, Coober Pedy Opal, Mintabie Opal, Andamooka matrix opal and boulder opal. Other opals, including Ethiopian Welo opal, Brazilian Opal, and Virgin Valley opal are shown.
The tests involve using Ultraviolet light to determine fluorescence and phosphorescence and the lick or finger test to test whether you are dealing with hydrophane (water-absorbing opal).
