Mica is characterized by its glittering, scale-like crystals. Golden Mica, known in Japanese as "Unmoseki" (Mica Stone), is a very rare and unusual natural stone that is rarely found in the market. Mica has the property of easily splitting in a certain direction along the crystal axis. It is believed to be effective for longevity and was prized as a medicinal stone. It creates a fantastic luster and shine depending on the angle of light, captivating viewers with its indescribable beauty.
