It looks like a colonail period button. It probably had shell of mother of pearl in the center. I had one about lke that that did. why the ringd weere attached I have no idea.
I agree that the style of the button itself looks early. I have seen some late 1800s buttons with rings attached before, but I am not sure what the function of the rings were. So you do think it's a button with a ring attached?
If there had been a backmark on it, I wouldn't have posted it here--since it would've been obvious what it was. But in light of the attached ring and lack of backmark I thought I'd better post it.
