Bird Nest Pin Brooch Gold Tone Wire Faux Pearl Eggs NOT Signed Vintage

This pin belonged to my mother and has simply sat in her jewelry box until we located it. It is in nice vintage condition, but I do see 2 small marks (perhaps gold tone flaking off a bit due to age). One is on the back of the pin so no one would ever notice it when worn and the other is ever so small on the outer ring of the nest by the birds beak. Not real noticeable, but it is there. There is no brand. About 2". I am assuming this is gold tone and not the real stuff. With that assumption I am also assuming the 3 pearls in the nest (eggs) are faux as well. However, I am no expert, so please look at all the photos and make your own determination. Please ask any questions before you buy. I try to describe everything the best I can. Thanks for stopping by and taking a look.
