Petrified wood is a type of fossil: it consists of fossil wood where all the organic materials have been replaced with minerals while retaining the original structure of the wood. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen. Mineral-rich water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay away, a stone mould forms in its place.
Elements such as manganese, iron and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red or other tint.
Following is a list of minerals and related color hues: Petrified Fern Log slices from Brazil originating from the Tietea singularis fern that flourished in the Permian Age 180-205 million years ago.

Indonesian Petrified Wood is from ancient teak (hardwood) trees that turned to stone. The 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. FREE FedEx Ground shipping within the (48) Continental United States!
