Beautiful ring :daydream: They do make synthetic ones, but they are not as nice as the real thing. Congrats on a really sweet ring. That is an early Indian for sure. Love Indians pre 1880. As for the button? Does it look like an old jeans button or is it possibly a small knob, like from a jewelry box or similar? If you have a black light, check that opal under it. if it glows (fluoresces) I think then it's real.
