Hi there, I am selling this Really nice Alabama Petrified Crystallized Wood Mineral Specimen .
It is really beautiful. It is a collectionpiece of mine that I have had.
Times are tough and I am trying to raise money, and I thought I would try selling off some things from my old collection.
I hope it finds a good home out there, and I am sure they will.
THIS AUCTION IS FOR THE MINERAL SPECIMEN WITH FREE SHIPPING IN THE US!!!
Petrified wood from Alabama is very unique. Unlike petrified wood specimens from almost anywhere else in the world, the specimens from Alabama are found completely covered in druzy smoky quartz. It is very beautiful and very sparkly! It comes from northwestern Alabama. This awesome little guy weighs 6.1 carats which is 1.23 grams and is 18 mm tall by 10 mm wide by 9 mm thick. If you have any questions, do not hesitate to ask me.
Have fun bidding, and know that I will ship this out the same day as the payment clears. Thanks so much for visiting my auction and have a great day:>)

Petrified wood (from the Greek root petro meaning "rock" or "stone"; literally "wood turned into stone") is the name given to a special type of fossilized remains of terrestrial vegetation. It is the result of a tree having turned completely into stone by the process of permineralization. All the organic materials have been replaced with minerals (most often a silicate , such as quartz ), while retaining the original structure of the wood. Unlike other types of fossils which are typically impressions or compressions, petrified wood is a three dimensional representation of the original organic material. The petrifaction process occurs underground, when wood becomes buried under sediment and is initially preserved due to a lack of oxygen which inhibits aerobic decomposition. Mineral-laden water flowing through the sediment deposits minerals in the plant's cells and as the plant's lignin and cellulose decay, a stone mould forms in its place.

In general, wood takes fewer than 100 years to petrify. The organic matter needs to become petrified before it decomposes completely. [1 ] A forest where the wood has petrified becomes known as a petrified forest .

Elements such as manganese , iron and copper in the water/mud during the petrification process give petrified wood a variety of color ranges. Pure quartz crystals are colorless, but when contaminants are added to the process the crystals take on a yellow, red, or other tint.

Following is a list of contaminating elements and related color hues:

carbon - black cobalt - green/blue chromium - green/blue copper - green/blue iron oxides - red, brown, and yellow manganese - pink/orange manganese oxides - black/yellow
