Petrified wood is in fact a kind of fossil, in which all organic materials have been replaced by minerals such as silicates and quartz over the course of millions of years. The structure of the wood was preserved.
The process of petrification takes place underground. This is because the tree gets buried by sediment, this process of petrification can take millions of years. The groundwater that slowly seeps through the soil deposits minerals, causing the lignin and cellulose to rot.
Depending on the rot and deposition, if they go at the same speed, the shape of the cells is maintained. This allows us to distinguish the growth rings of the tree in some cases and we can see the smallest details.
We come across petrified wood in all kinds of colors due to the variation of deposits of minerals such as iron, copper, manganese etc.
Petrified wood is also attributed a healing effect. It brings the wearer zest for life and shows him the positive sides of life. Promotes detoxification and excretion.
