Petrified Wood with Blue Opal was first found as pebbles and larger rounded stones (“cobbles”) in streams and near the slopes of three volcanoes in Indonesia’s West Java Province. The source deposit was finally located on the steep slopes of Mt. Tjikolak a mere 4 years ago. What the miners had found was an ancient petrified forest which had been pushed over by the deluge of “stuff” (pyroclastic flow) from a volcanic explosion. Then, over the ages, the wood was fossilized and preserved by opaline silica.
Once the tree’s organic material (the wood) actually decomposed, which took thousands of years, it was replaced with opaline silica. The water in that silica was very rich in dissolved copper, iron, and manganese. Those copper and manganese deposits are now found inside this blue opal - or gem silica as it is really. 'Blue opal' being a trade name really. It is not blue opal.
