How to perform a very simple test at home to determine if your opal is hydrophane.
To be clear: Not all Ethiopian opals are hydrophane, however, this is a very good start to determining the origin for your opal.
This test is generally non-destructive, but there is always a risk that your opal could crack as it dries out. After performing this test, opals should be dried out very very slowly, over the course of weeks or months to decrease their chance of crazing when drying out.
