Gorham Sterling Silver Yellow Gold Vermeil Pin Brooch - Etched Heart Center

From Gorham, may I offer this Sterling Silver (hallmarked as pictured) and yellow gold vermeil pin - brooch. In a round shape, the front of the piece display a bit of curlicue etching as well as a puffy heart. Size is 1-7/16" high/wide; weight is 11.2 grams. Safety catch at the back to hold the pinstem in place. Condition is very nice with no problems I can spot. Age? I'm guessing but maybe the end of the 1980s, early 1990s. Just too cute!
