Vintage Weiss Trembler Butterfly Brooch

Love, Love, Love, this brooch! There is a yellow enamel flower with a faceted amber rhinestone in the center. Then the butterfly is on a trembler and has pink yellow, and blue stones on his wings. This pin measures about 3″ long. The back is marked: “Weiss” . This dates to the 1950-60’s. There is minor wear from age, but still lovely when wearing!
