■ Size: Grain diameter 12mm (±0.5mm), inner circumference 175mm (±5mm) Hokutoite is a natural monument in both Taiwan and Japan, and no new stones are mined. This product is made from powdered Hokutoite mined in Taiwan before mining was banned, baked into ceramic (pottery). Color can be added by mixing soil into the ceramic during baking. This product is a new product that has successfully achieved a black color by fine-tuning the powder's composition during kneading. It will be shipped in a case bearing the GOLD STONE logo.
