This is a brooch pendant featuring "Higo Zogan," a traditional craft of Kumamoto. Higo Zogan involves shaping pure gold, pure silver, and other precious metals into designs and inlaying them into iron. It originated when Hosokawa Sansai, the feudal lord of the Edo period, had weaponry made, and items like sword guards (tsuba) were prized by daimyo and prominent families. This piece is by the Osumi family, of Kosuke, who have been supplying sword tsuba to Kumamoto Castle since the Edo period. Condition: Unused. The box shows some deterioration due to age. Materials: Zogan body = iron, pure gold; base, chain = gold plating Thank you.
