These pieces of petrified wood are found and processed in Indonesia. Petrified wood from Indonesia is roughly between 23 and 75 million years. The petrified wood that we offer is of the older stock, that lived the Cretaceous period. Wood becomes fossilized when a plant gets covered by sediment or volcanic ash. With the input of water, the parts of the plant gets slowly replaced by minerals. This process can take a very long time. The polished end result is what we offer.
