Vintage Freirich Brooch Mid Century Gold Tone Filigree Faux Milk Glass Minty

Freirich Vintage Brooch that is difficult to find with this shape of the white cabochon. The filigree is in excellent, vintage condition. Please see the photo closely for your consideration. This particular mark was used in 1964-1990. My best educated guess is to put this piece in the 1960s based on the style. This is when the company was running in the US. They made high end buttons for Dior and other houses.
