The price per gram of any cute chip.
Some excellent samples of petrified wood were found in the Rostov region, near the river Kalavinka,and completely random...
All fragments of the original microscopic structure of wood. The color of the fossilized fragments of white and sometimes pale - beige or coffee,which will be noticed, is not often found.
As all this takes place in nature?- the question...
-When wood becomes buried under sediment, the process of fossilization begins under the ground ,the tree that time does not deteriorate due to
the fact that the oxygen was practically absent...
Mineral-rich water flowing through the sediment, brings minerals into the cells of plants, and when the lignin and cellulose decay, stone is repeating original form. All organic matter replaced by minerals, in this case opal.
Opal low density,it seems that fossils are very light.
Opal is hygroscopic - adheres to the tongue,as chrysocolla or turquoise and has a characteristic waxy luster on the chips.
The presence of certain impurities and chemical elements such as iron, manganese, copper, and water (mud) during the petrification process, gives petrified wood created a particular color from a fairly wide range of colors.
Petrified wood has long been used as a raw material for jewelry. The value of samples associated with a specific shape, pattern and age of many million years, which is appreciated by collectors.
