Harriet Carter Heart Brooch W/ Emerald Gold Plated

Vintage from the 1980's new in sealed plastic heart pin from Harriet Carter. This was purchased from the catalog. I had long forgotten about it sitting in a jewelry box Packaging says "Genuine Emerald 24 Karat Gold Electroplated. Made in USA for Harriet Carter." Pin measures 3/4" by 3/4". Would make a great gift for those born in May Emerald is the birthstone for that month
