This is an original 18th century Gouyn period porcelain Chelsea fob seal. These seals were given as love tokens by the wealthy and known as "toys". This particular seal features a nun with her gilded black cape holding a staff and reading from a book. The seal reads in red letters, "Amour Spirituel", ("Spiritual Love"). The black cape with gold edging is in particularly fine condition.
Charles Gouyn, a French jeweler, with Nicholas Sprimont, a silversmith founded the Chelsea Factory in 1743. This is an original seal from the era in which Gouyn was manager of the Chelsea Factory.
