FLORENZA 1960s Netsuke of Smiling East-Asian Man

Netsuke Pendant of an East-Asian man in country garb, signed 'Florenza©', a mark of the Florenza Jewelry Company of NYC Given to my grandmother between 1958 and 1972. Two identical pendants were recently listed for sale on online auction sites. Both were being sold with long gold-tone chains of unknown material. I can't find a similar necklace in my grandmother's or mother's jewelry, so instead have included the 20" gold-tone rope chain seen in the photos. Approximately 1-1/4" x 7/8" x 3/8".
