This is a fantastic, very early Coro piece, with enamel detail on gold toned pot metal. It's in great condition with what looks to be the original center stone. It has a lot of smoothed edges to the cut glass, giving it a very authentic antique feel.The photos give it a slightly red look but it's a very solid rich deep amethyst color. I can't really tell if it's signed or not. The location that the signature would be isn't instantly visible, so on the safe side I'm gonna to say it's not signed, but in some light I think I can see it. If you look at the other Coro Ostrich pieces, you will be able to compare and know it's a great vintage Coro piece.
