6.1" Polished Petrified Shrinkwood Slab - Colorado

This is a colorful 6.1" slab of petrified shrinkwood that was collected from Colorado. The term "shrinkwood" refers to wood that following preservation, became fragmented, resulting in small cavities that become naturally "glued" back together by silica-rich fluids (chalcedony).

It has been polished to a glossy finish by one of the best polishers around. It doesn't have any of the tool marks or scuffing that might be left by lesser quality polishers. 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.
