Antique Butterfly Wing Hand Painted Tropical Ring

Antique genuine Morpho butterfly wing hand-painted silver Art Deco ring from the 1920's. Some light scratch marks to the surface glass, and the butterfly wings natural blue colour seems to have worn off in one part of the scene, but, considering it's age, and the fact that it is a true, rare antique ring, I would say it is in good vintage condition. Ring is unmarked. Ring band is adjustable, but only from size 7 onwards. I don't suggest making the ring any smaller than this.
