Vintage Victorian style Bohemian gold plated necklace, filigree, with faux pearl

Vintage gold plated necklace. Bohemian, Victorian style. Filigree, with white faux pearl. 17" chain 1" pendant. The pendant is very old and was repurposed from some other piece of jewelry, possibly a brooch, as can be seen in the picture of the back. There is some wear on both the pendant and the chain, in a very uniform way, such that they look very retro and with patina.
