another group of brooches

[familycollectiblesstore]

Just a few more, I am probably boring the heck out of you all, sorry, the square pin I think is amythest, very prett purple stones, the green and white is very layered...1-4, left to right, any thoughts of makers and time periods? Thank You, I had no idea this box held so many brooches...

The circular one is probably the oldest, 20s to 40s maybe. The layered fleur de lis one may be Coro, their mark is sometimes hard to see if its there at all but they did do this type of brooch
