When I purchased this piece from another dealer, she told me that it was a Wiesner piece. The quality is such that it is likely one of his pieces from the 1950's. The emerald-cut stones have amazing sparkle and clarity and the color is delicious...like a bright crisp green apple! The shape of this brooch is elegant and it would look spectacular on your little black dress, a suit jacket or a coat. Measuring 2-3/8" x 1-1/2", this would be an excellent addition to a collection or as a gift. The safety clasp closes tightly to keep this gem secure.
