The man decided to take the piece of wood to the city for appraisal. The expert told him that it was not jade but natural petrified wood . What is petrified wood?

According to experts, the phenomenon of petrified wood is a strange phenomenon of nature. This process takes place over millions of years underground and to create a petrified wood is very rare, it can be considered as precious as gold.

Petrified wood comes from primeval forests. After the impact of a volcanic eruption, these tree trunks were buried in lava for millions of years and gradually turned into jade.

In areas where dead trees are covered with various minerals from volcanic eruptions, these minerals will penetrate into the wood capillaries. As the structure of the wood gradually breaks down, the wood fibers are replaced by other inorganic minerals such as quartz, opal, chalcedony, etc.

These petrified trees have existed mainly since the Triassic and Jurassic periods, about 100 million to 250 million years ago. In principle, petrified wood has a similar process to fossilized animal bones and skeletons. This process is continuous and depending on the replaced minerals, it forms petrified wood with different properties and hardness.

Western theologians believe that the original is a rotten log, after going through the process of quartzization, it turns into a precious stone, so the fossil wood has the properties of a sustainable magnetic field, longevity, and eternity.

The color of the jade tree trunk is also diverse: gray and brown are the most common, but there are also red, orange, yellow, black and the rarest is jade green .

Since ancient times, such as Assyria, Babylon and ancient Rome, petrified wood has been used as an artistic stone. From petrified wood, people have made necklaces, rings, pendants and pendants. Since the 19th and 20th centuries, small tables, vases and candle holders have been crafted from petrified wood exported from Arizona.

Compared to ordinary wood, petrified wood is many times more valuable. Once petrified, it is classified as a precious stone. Experts say that the man's petrified wood is about 200 million years old. The economic value of the wood is huge and its research value is also very high.
