In Japan, it was designated as a natural monument in 1922 and a special natural monument in 1952, and mining is currently prohibited. This product is Hokutolite purchased from a Taiwanese vendor who owns a factory that processes the raw stone. It is said to be effective for promoting health by emitting radiation due to its radium content. Hokutolite is said to be a "doctor-free" stone that is good for health due to the hormesis effect caused by its radium content, and it is often featured in the media for generating negative ions. Hokutolite commonly sold as round beads is made by processing Hokutolite powder/small pieces with ceramic, but this does not affect the stone's effectiveness. *Notes before purchase* *We try to photograph the product in colors as close to the actual item as possible, but the colors may appear different depending on your monitor or smartphone.
