Rare Vintage Gold Tone and Porcelain Flowered Brooch, Signed

This pretty little brooch is very unique. When you first look at it, you'll think a piece of the flower is broken off,but that's not the case. Look closely, and you will see that the piece (petal) is folded back - just as real flowers do. How clever is that? It is signed "JEANNE". I love how the gold follows through to the center of the flower.
