The story behind petrified wood is almost as old as history itself. It begins with a volcano erupting on one of the 17,000 archipelagos in Indonesia. The trees blown into river beds become covered in sediment and ash. Then over just a couple million years, the wood turns to stone!

Indonesian Blue Petrified Wood is from ancient teak (hardwood) trees that turned to stone. The Blue Petrified Wood is from trees approximately 20 million years old. Minerals present in the mud and water prior to and during the petrification process leached into the wood giving it color.

Petrified Wood comes from the Greek root petro, which means rock or stone, with literal meaning'wood turned into stone'. It's the name given to the fossilized remains of terrestrial vegetation.

Petrified Wood with Blue Opal was first found as pebbles and larger rounded stones in streams and near the slopes of three volcanoes in region of Indonesia's Garut, West Java Province, nearly 300km away from Soekarno-Hatta airport. The source deposit was finally located on the steep slopes of Mt. Tjikolak almost 30 years ago, and going popular into public around 2017. What the miners actually found was an ancient petrified forest, which had been pushed over by the deluge of pyroclastic flow from a volcanic explosion. Then, over the ages, the wood was fossilized and preserved by opaline silica. In short explanation, all those fallen trees on the slope after the eruption of mountain, covered with other layers of the debris of thousands of years in the future.
