Vintage Blue Morphos Butterfly Wing/Reverse Painted Sweater Clip 1940s

If you know anything about vintage blue morphos butterfly jewelry, then you know the way the wings glow when turned this way and that behind the reverse painted sailboat motifs on each end of the sweater clip. These are unique domes of glass with a fancy edge around the oval. They have an earring-like clip but wouldn't be easy on the ears. Theres a ""faux"" pearl chain between the two. Almost 1 inch long each, and the chain is 7"" ; mint condition.
