HOT ! VTG Pink Enamel Flower Brooch and Earrings Clip On Gold Tone -Flaw- Please read

Brooch approx. 2" diameter, Earrings a bit over 1" diameter.
I had this set - a brooch and clip earrings - stored away since the 1960s. I believe it was a gift, probably for my graduation. I never wore it. However, there is a chip on one flower which probably happened from rubbing against other jewelry. If I were keeping this I would probably leave as is or use nail polish to fix it. 
I had a horrible time getting the correct color in pictures and, of course, each device shows color differently. These are definitely bright or hot pink and have red highlights on the edges of the flowers. The earrings are a slightly lighter color of pink, one a bit lighter than the other, but I wouldn't expect them to look that different when wearing them. Please look at all the pictures to try to get a better idea of the color. 
I'm not sure what kind of metal this is, but it is gold tone. There are no markings on any of the items. Please see pictures of the backs of all three.
