10.4" Opalized Petrified Wood (Elm) Round - Oregon
This is a 10.4" wide, polished round of opalized petrified (elm) wood from Oregon. It has wonderful color with the preserved tree-rings still visible. In most cased petrified wood is replaced with chalcedony but in rare cases it can be replaced with opal instead. Opalized wood is much softer, less dense and has a lower refractive index than chalcedony replaced petrified wood.
This round has been polished to a glossy finish on one side, backed with with fiberglass/epoxy for stability and comes with a display stand.

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.
