Wonderful pietra dura mosaic pin with ornate floral design is set in (tested) sterling with a gold wash. The stone inlay flowers have shades of brown, green, white, and a splash of red! The frame has a scalloped rope design too, for added interest.
The brooch has a retractable bail so this can also be worn as a pendant. It is not marked and in excellent condition.
It measures 1.5 x 1 1/8 inches.
I also have a charming pietra dura ring in my shop. Please see the last photo.
