This pretty and petite 1960s Flower Power pin and earrings set were purchased from the same estate but they're probably not a matching set. The colors are the same, bright hot pink and a lighter shade of Pepto pink. The domed, dimensional flower brooch is just shy of 2 inches diameter. One of the center stamen posts is missing enamel.
The multi-petaled clip earrings are 1 inch diameter. The center petals are the same hot pink as the upper petals in the pin. The outer petals are lighter pink, a bit darker than the lighter pin petals. A few petals have pinpoint enamel loss on the thin petal edges only. This is much more noticeable in the greatly enlarged photos.
