Vintage dappled red copper unsigned Matisse neck

This mid-century copper necklace is probably Matisse. The hook may have been replaced eliminating the signature. The necklace consists of red enameled scalloped links that are speckled with white and black dots. There is a cage of copper layered over the enamel. The back is also an emerald in a peach color enamel. It is 18 in in mine condition is very good.
