6.7" Jasper/Agate Replaced Petrified Wood - Indonesia

This specimen features petrified wood that has undergone jasper and agate replacement. The petrified wood was likely from a Miocene-aged tropical hardwood tree, deposited roughly 20 million years ago near Java, Indonesia. Typically in replacement like this, all of the wood grain detail is lost, however this petrified wood specimen still retained some of the rings.

It has been cut flat one both sides and polished to a glossy finish on one side, though it doesn't maintain a uniform thickness across the entire specimen. Comes with an a acrylic display stand.

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