Vermillion Obsidian

Red Tokachi Stone (Vermilion Obsidian)

Obsidian was created approximately 1.5 million years ago by intense volcanic activity in Mount Daisetsu.
It has long been used to make tools such as arrowheads and knives.
As it flows through the river, the outside becomes scratched and whitish, but some of it has a faint, pitch-black glassy appearance visible from the outside.
Among them, the red ones are called vermilion obsidian locally and are now rare.

Obsidian was generated by a furious volcanic activity of Mt Daisetsu about 1.5 million years ago.
Processed into tools like arrowheads and knives, obsidian has been loved by people since prehistoric days.
There are types that looks a little white because they were floating in the river, and others contain pitch black glassy texture that are spotted from the outside. Also, types with red texture have been collected from time to time and they're called Vermillion Obsidian. Now it`s becoming difficult to obtain.
