Late 19th century 18k yellow gold brooch has micro mosaic depiction man sitting on bench.

Most likely a souvenir of a Grand Tour.

Oval black onyx stone with the amazing mosaic work in the center.

The 18k solid yellow gold frame has very fine detail.

The pin is an open "C" clasp typical of the period.

The gold content is not marked, but it was carefully acid-tested as 18k.

Very good condition. There are some numbers scratched on the back of the onyx.

Measures 1 3/4" by 1 1/4'.
