In ancient times, it was called "gyoku" (jade). Itoigawa jade, the national stone of Japan, was formed about 520 million years ago and is said to be "the oldest jade in the world." Currently, the collection of Itoigawa jade is prohibited, and only those washed ashore on the coast are permitted to be collected.
