In Japan, it was designated as a natural monument in 1922 and a special natural monument in 1952, and mining is now prohibited. This product is Hokutolite purchased from a Taiwanese vendor who has a factory that processes the raw stone. It is said to have health-promoting effects by emitting radiation due to the inclusion of radium. Because Hokutolite contains radium, it is said to be a "doctor-free" stone that is good for health due to the hormesis effect, and it is often featured in the media for generating negative ions. Hokutolite that is generally distributed as round beads is processed with Hokutolite powder and small pieces using ceramics, but this does not affect the stone's effectiveness. *Notes before purchase* ※We try to photograph the colors as close to the actual product as possible, but the colors may appear different depending on your monitor or smartphone.
