5.9" Petrified Wood (Woodworthia) Round With Crystal Pocket - Zimbabwe

This is a beautiful, polished slab of Triassic aged petrified wood collected near Gokwe, Zimbabwe. It is from Woodworthia, a primitive conifer and the green coloration can be attributed to chromium impurities. One side has been polished to a mirror like finish, showing off the gorgeous inner wood detail.

There is a quartz crystal filled pocket at the center of this slab. It comes with an acrylic display stand.

Petrified wood is the name given to wood that has been turned into stone (fossilized) through the process of permineralization. All of the organic matter becomes replaced by minerals, while much of the original structure such as tree rings in retained. For this to happen the wood needs to be buried in an environment both low in oxygen (preventing decomposition) and with flowing, mineral-laden water. The coloration is due to the various minerals that are present during fossilization. For example red colors are due to iron compounds, greens due to copper, etc.
