The vintage earrings are mounted in a heart shape silver setting with a tropical palm tree landscape. Iridescent butterfly wings are used combined with a painted silhouette on the back of a Lucite dome to make the landscape scene. This technique is called reverse painting. The background is mostly blue. The earrings are screw back in good working condition. The are approximately 1/2" NS and 11/16" EW. I find no maker's mark . This type of earring was popular during the 1940's-50's.
