Vintage silver tone and red glass cabochon flower design combined brooch and scarf clip, trombone clasp, perhaps made in France

Beautiful vintage dress / fur / scarf clip convertible to a brooch from the Art Deco period. I hadn't seen another like this one - with the pin and trombone clasp for a brooch mounted on top of a hinged scarf clip ring, until I found this and two others listed on my site in quick succession.

This one has a pretty floral design with a large, round central red glass cabochon.

The clip can also be used as a pendant by simply clipping it over a chain or necklace and obviously the loop can be used to thread the ends of a scarf through as well. This works well, giving the piece versatility of function. It the clip has a diameter of about 1 1/4 inches. It looks so much like silver, I was surprised to find it did not test positive for sterling or any grade silver.

This clip is in very good vintage condition. Please examine all the photos carefully for a full condition report and message me with any questions.
