opal has been a gemstone that lots of people love and some adore with a passion. I fit into the second category, probably because opal is about the only gemstone that can have such a diverse brilliance of colour that encompasses the whole of the colour spectrum. Because of this I find it such an uplifting and beautiful stone.
The opals are found in a nodular form within a continuous layer of welded volcanic ash (tuff, similar to obsidian in character), about 3 metres thick, that lies between weathered rhyolite layers.
