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 10 months ago. What the miners actually found was an ancient petrified forest (how cool is that?), 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. In my mind’s eye, I see all those fallen trees on the slope after the eruption of Mount St. Helens, covered with other layers of the debris of thousands of years in the future. Now, this is where it gets really interesting! 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!
