5.1" Polished Petrified Chrysocolla Wood End-Cut - Indonesia
This is 5.1 x 3.6" by 3.1" thick, polished end-cut of petrified chrysocolla wood from Indonesia. This rare petrified wood exhibits a mixture of chalcedony and chrysocolla replacement, with small spots of green malachite. Wood grain detail can be seen along one edge of this specimen. This likely occurred as a result of the wood being preserved in a copper-rich environment, similar to "colla-wood" from Turkey.
What Is Petrified Wood
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.
