Black Hokutolite Bracelet Taiwanese Negative ion Radium Black Inner diameter 19cm [GOLD STONE] 10mm, origin, tested, Hokutolite, approx.

Grain diameter 10mm (±0.5mm) Inner diameter 19cm *The photo shows a product with an inner diameter of 15.5cm. Hokutolite is a natural monument in both Taiwan and Japan, and no new specimens are being mined. This product is made by firing powdered Hokutolite, which was mined in Taiwan before mining was banned, into ceramic (pottery). By mixing clay or other materials into the ceramic during the firing process, it's possible to add color. This new product successfully achieves a black color by finely adjusting the powder's composition during the mixing process of the Hokutolite powder. Taiwanese Hokutolite is found only in two places in the world: Beitou Hot Springs in Taiwan and Tamagawa Hot Springs in Akita Prefecture. It is an extremely rare mineral. Beitoulite from Taiwan is an extremely valuable mineral, and its illegal mining is prohibited. Hokutolite beads are ceramic balls made by stirring powdered Hokutolite from Hokutou Hot Springs in Taiwan to a consistent radiation level and then firing it. Hokutolite, which has attracted attention in the media such as on television, emits trace amounts of radiation from its hot spring components. It is also known as the "stone that eliminates the need for doctors." It emits negative ions, and its ion level can be measured with an ion tester. *This product is a new product that successfully achieves a black color by finely adjusting the powder's composition when mixing in the Hokutolite powder. Of course, when measured with an ion tester, it can be measured at a similar level to that of the regular color.
