What kind of wood is this black piece of wood fished out of the river? Everyone knows that the wood is so hard that even a chainsaw cannot cut it.

It’s ebony, quite valuable!

Ebony (gloomy wood) combines the elegance of wood and the charm of stone. It is known as the "Oriental Sacred Wood" and "Plant Mummy". Earthquakes, floods, and mudslides buried all ground plants and organisms into low-lying areas such as ancient river beds. Some trees buried in the mud undergo a carbonization process that lasts for thousands of years under the action of bacteria and other microorganisms under conditions of hypoxia, high pressure, and the formation of ebony, so it is also called "carbonized wood." Throughout the ages, ebony has been used to ward off evil spirits, making handicrafts, Buddha statues, and amulet pendants. An ancient saying goes: "Half a square of ebony at home is worth more than a box of treasure."
