Vintage brooches

Some new additions to my ever-growing collection of vintage brooches. These were a recent purchase, not a legacy from my favorite aunt. They are both unmarked although the autumnal colored one is marked "Made is Austria." The purple one seems to be constructed oddly, differently from others that I own. Does this mean that it's a reproduction of a vintage brooch? I bought it because it was pretty. Any information is greatly appreciated. Thanks!
