Vintage Unbranded Yellow Gold Tone Metal Flower Pin Brooch

Dating to the 1960s or so, here's a stunning yellow gold tone metal pin/brooch by an unknown maker. In the shape of a single flower (lots of curlicue filigree), the pin is very well made with no problems I can spot. Size is 2-3/16" long x 1-1/4" wide. Safety catch at the back to hold the pinstem in place. Just lovely!
